# security encryption file-transfer noise-protocol critical-fix
**CRITICAL SECURITY VULNERABILITY FIXED: Private File Transfers Now Properly Noise Encrypted**
**Problem**: Audio messages, images, and files sent in private chats were being sent as unencrypted FILE_TRANSFER packets, exposing private file content to the entire mesh network.
**Root Cause**: The sendFilePrivate() method in BluetoothMeshService.kt was creating FILE_TRANSFER packets with the raw TLV payload, not encrypting them through the Noise protocol like text messages.
**Security Impact**:
- Private images were visible to all mesh participants
- Private voice recordings were audible to all mesh participants
- Private file contents were readable by all mesh participants
- Only the filename/metadata was somewhat obscured by TLV encoding
**Fix Applied**:
1. **Updated NoisePayloadType enum** (NoiseEncrypted.kt):
- Added FILE_TRANSFER(0x04u) payload type for encrypted file transfers
2. **Fixed sendFilePrivate()** (BluetoothMeshService.kt):
- Now wraps file TLV in NoisePayload with FILE_TRANSFER type
- Encrypts through encryptionService.encrypt() like text messages
- Sends as NOISE_ENCRYPTED packet (not FILE_TRANSFER packet)
- Requires established Noise session; initiates handshake if missing
- Maintains same fragmentation and progress tracking
3. **Enhanced handleNoiseEncrypted()** (MessageHandler.kt):
- Added NoisePayloadType.FILE_TRANSFER case
- Decrypts file payload and processes like unencrypted files
- Maintains same MIME-based classification (image/audio/file)
- Sends delivery ACK for encrypted file transfers
**Technical Details**:
- **Broadcast files**: Still unencrypted FILE_TRANSFER (public by design)
- **Private files**: Now encrypted via NOISE_ENCRYPTED with FILE_TRANSFER NoisePayload
- **Backward compatibility**: Mixed mesh will work (new private sends encrypted, old broadcast path unchanged)
- **iOS compatibility**: Uses same NoisePayload system as iOS implementation
**Files Modified**:
- app/src/main/java/com/bitchat/android/model/NoiseEncrypted.kt - Added FILE_TRANSFER payload type
- app/src/main/java/com/bitchat/android/mesh/BluetoothMeshService.kt - Fixed sendFilePrivate() encryption
- app/src/main/java/com/bitchat/android/mesh/MessageHandler.kt - Added encrypted file receive handling
**Build Status**: ✅ Successful compilation
**Result**: Private file transfers (images, audio, generic files) are now properly end-to-end encrypted and only visible to the intended recipient, matching the security model of private text messages.

/**
* BitchatFilePacket: TLV-encoded file transfer payload for BLE mesh.
* TLVs:
* - 0x01: filename (UTF-8)
* - 0x02: file size (8 bytes, UInt64)
* - 0x03: mime type (UTF-8)
* - 0x04: content (bytes) — may appear multiple times for large files
*
* Length field for TLV is 2 bytes (UInt16, big-endian) for all TLVs.
* For large files, CONTENT is chunked into multiple TLVs of up to 65535 bytes each.
*
* Note: The outer BitchatPacket uses version 2 (4-byte payload length), so this
* TLV payload can exceed 64 KiB even though each TLV value is limited to 65535 bytes.
* Transport-level fragmentation then splits the final packet for BLE MTU.

# Device Monitoring Manager — Design and Integration
This change introduces a lean DeviceMonitoringManager to strictly manage BLE device connections while keeping the existing code structure intact.
## Goals
- Maintain a blocklist of device MAC addresses to deny incoming/outgoing connections.
- Drop and block connections that never ANNOUNCE within 15 seconds of establishment.
- Drop and block connections that go silent (no packets) for over 60 seconds.
- Block devices that experience 5 error disconnects within a 5-minute window.
- Auto-unblock devices after 15 minutes.
## Implementation Overview
File: `app/src/main/java/com/bitchat/android/mesh/DeviceMonitoringManager.kt`
- Thread-safe maps with coroutine-based timers.
- Minimal surface area: a few clearly named entry points to hook into existing flows.
- Callbacks to perform disconnects without coupling to GATT APIs.
Key logic:
- `isBlocked(address)`: check if a MAC is blocked (auto-clears on expiry).
- `block(address, reason)`: add MAC to blocklist (15m), disconnect via callback, auto-unblock later.
- `onConnectionEstablished(address)`: start 15s “first ANNOUNCE” timer and a 60s inactivity timer.
- `onAnnounceReceived(address)`: cancel the 15s ANNOUNCE timer for that device.
- `onAnyPacketReceived(address)`: refresh 60s inactivity timer.
- `onDeviceDisconnected(address, status)`: track error disconnects and block on 5 within 5 minutes.
Timers:
- ANNOUNCE timer: 15 seconds from connection establishment.
- Inactivity timer: resets on any packet; fires after 60 seconds of silence.
- Blocklist TTL: 15 minutes per device (auto-unblock job per entry).
## Wiring Points (Minimal Changes)
1) Connection Manager
- File: `BluetoothConnectionManager.kt`
- Added a `DeviceMonitoringManager` instance and provided a `disconnectCallback` that:
- disconnects client GATT connections via `BluetoothConnectionTracker`.
- cancels server connections via `BluetoothGattServer.cancelConnection`.
- Exposed `noteAnnounceReceived(address)` as a small helper for higher layers.
- Updated `componentDelegate.onPacketReceived` to notify per-device activity to the monitor.
2) GATT Client
- File: `BluetoothGattClientManager.kt`
- Constructor now receives `deviceMonitor`.
- Before attempting any outgoing connection (from scan or direct connect), deny if blocked.
- On connection setup complete (after CCCD enable), call `deviceMonitor.onConnectionEstablished(addr)`.
- On incoming packet (`onCharacteristicChanged`), call `deviceMonitor.onAnyPacketReceived(addr)`.
- On disconnect, call `deviceMonitor.onDeviceDisconnected(addr, status)` to track error bursts.
3) GATT Server
- File: `BluetoothGattServerManager.kt`
- Constructor now receives `deviceMonitor`.
- On incoming connection, immediately deny (cancelConnection) if blocked, before tracking it.
- On connection setup complete (descriptor enable) and also after initial connect, start monitoring via `onConnectionEstablished(addr)`.
- On packet write, call `deviceMonitor.onAnyPacketReceived(addr)`.
- On disconnect, call `deviceMonitor.onDeviceDisconnected(addr, status)`.
4) ANNOUNCE Binding
- File: `BluetoothMeshService.kt` (in the ANNOUNCE handler where we first map device → peer)
- After mapping a device address to a peer on first verified ANNOUNCE, call `connectionManager.noteAnnounceReceived(address)` to cancel the 15s timer for that device.
## Behavior Summary
- Blocked devices:
- Outgoing: client will not initiate connections.
- Incoming: server cancels the connection immediately.
- Existing connection: monitor disconnects instantly and blocks for 15 minutes.
- No ANNOUNCE within 15s of connection:
- Connection is dropped and device is blocked for 15 minutes.
- No packets for >60s:
- Connection is dropped and device is blocked for 15 minutes.
- >=5 error disconnects within 5 minutes:
- Device is blocked for 15 minutes.
- Auto-unblock:
- Every block entry automatically expires after 15 minutes.
## Debug Logging
- The manager emits chat-visible debug messages through `DebugSettingsManager` (SystemMessage), e.g.:
- Blocking decisions and reasons
- Auto-unblock events
- ANNOUNCE wait start/cancel
- Inactivity timer set and inactivity-triggered blocks
- Burst error disconnect threshold reached
- Additional enforcement logs are added in GATT client/server when a blocked device is denied.
- Logs appear in the chat when verbose logging is enabled in Debug settings.
## Panic Triple-Tap
- Triple-tapping the title now also clears the device blocklist and all device tracking:
- Calls `BluetoothMeshService.clearAllInternalData()` which triggers `BluetoothConnectionManager.clearDeviceMonitoringAndTracking()`.
- This disconnects active connections, clears the monitors blocklist and timers, and resets the `BluetoothConnectionTracker` state.
## Notes and Rationale
- The monitoring manager is intentionally decoupled from GATT specifics via a disconnect callback. This keeps responsibilities separate and avoids plumbing GATT instances through unrelated classes.
- Packet activity is captured in both client and server data paths as early as possible to ensure the inactivity timer is accurate even before higher-level processing.
- The “first ANNOUNCE” check uses the same mapping event that sets `addressPeerMap` to avoid false positives on unverified announces.
## Touched Files
- Added: `mesh/DeviceMonitoringManager.kt`
- Updated: `mesh/BluetoothConnectionManager.kt`
- Updated: `mesh/BluetoothGattClientManager.kt`
- Updated: `mesh/BluetoothGattServerManager.kt`
- Updated: `mesh/BluetoothMeshService.kt`
These changes are small, local, and respect existing structure without broad refactors.

# Bitchat Bluetooth File Transfer: Images, Audio, and Generic Files (with Interactive Features)
This document is the exhaustive implementation guide for Bitchats Bluetooth file transfer protocol for voice notes (audio) and images, including interactive features like waveform seeking. It describes the onwire packet format (both v1 and v2), fragmentation/progress/cancellation, sender/receiver behaviors, and the complete UX we implemented in the Android client so that other implementers can interoperate and match the user experience precisely.
**Protocol Versions:**
- **v1**: Original protocol with 2byte payload length (≤ 64 KiB files)
- **v2**: Extended protocol with 4-byte payload length (≤ 4 GiB files) - use for all file transfers
- File transfer packets use v2 format by default for optimal compatibility
**Interactive Features:**
- **Waveform Seeking**: Tap anywhere on audio waveforms to jump to that playback position
- **Large File Support**: v2 protocol enables multi-GiB file transfers through fragmentation
- **Unified Experience**: Identical UX between platforms with enhanced user control
The guide is organized into:
- Protocol overview (BitchatPacket + File Transfer payload)
- Fragmentation, progress reporting, and cancellation
- Receive path, validation, and persistence
- Sender path (audio + images)
- Interactive features (audio waveform seeking)
- UI/UX behavior (recording, sending, playback, image rendering)
- File inventory (source files and their roles)
---
## 1) Protocol Overview
Bitchat BLE transport carries application messages inside the common `BitchatPacket` envelope. File transfer reuses the same envelope as public and private messages, with a distinct `type` and a TLVencoded payload.
### 1.1 BitchatPacket envelope
Fields (subset relevant to file transfer):
- `version: UByte` — protocol version (`1` for v1, `2` for v2 with extended payload length).
- `type: UByte` — message type. File transfer uses `MessageType.FILE_TRANSFER (0x22)`.
- `senderID: ByteArray (8)` — 8byte binary peer ID.
- `recipientID: ByteArray (8)` — 8byte recipient. For public: `SpecialRecipients.BROADCAST (0xFF…FF)`; for private: the target peers 8byte ID.
- `timestamp: ULong` — milliseconds since epoch.
- `payload: ByteArray` — TLV file payload (see below).
- `signature: ByteArray?` — optional signature (present for private sends in our implementation, to match iOS integrity path).
- `ttl: UByte` — hop TTL (we use `MAX_TTL` for broadcast, `7` for private).
Envelope creation and broadcast paths are implemented in:
- `app/src/main/java/com/bitchat/android/mesh/BluetoothMeshService.kt` (/Users/cc/git/bitchat-android/app/src/main/java/com/bitchat/android/mesh/BluetoothMeshService.kt)
- `app/src/main/java/com/bitchat/android/mesh/BluetoothConnectionManager.kt` (/Users/cc/git/bitchat-android/app/src/main/java/com/bitchat/android/mesh/BluetoothConnectionManager.kt)
- `app/src/main/java/com/bitchat/android/mesh/PacketProcessor.kt` (/Users/cc/git/bitchat-android/app/src/main/java/com/bitchat/android/mesh/PacketProcessor.kt)
Private sends are additionally encrypted at the higher layer (Noise) for text messages, but file transfers use the `FILE_TRANSFER` message type in the clear at the envelope level with content carried inside a TLV. See code for any deploymentspecific enforcement.
### 1.2 Binary Protocol Extensions (v2)
#### v2 Header Format Changes
**v1 Format (original):**
```
Header (13 bytes):
Version: 1 byte
Type: 1 byte
TTL: 1 byte
Timestamp: 8 bytes
Flags: 1 byte
PayloadLength: 2 bytes (big-endian, max 64 KiB)
```
**v2 Format (extended):**
```
Header (15 bytes):
Version: 1 byte (set to 2 for v2 packets)
Type: 1 byte
TTL: 1 byte
Timestamp: 8 bytes
Flags: 1 byte
PayloadLength: 4 bytes (big-endian, max ~4 GiB)
```
- **Header Size**: Increased from 13 to 15 bytes.
- **Payload Length Field**: Extended from 16 bits (2 bytes) to 32 bits (4 bytes), allowing file transfers up to ~4 GiB.
- **Backward Compatibility**: Clients must support both v1 and v2 decoding. File transfer packets always use v2.
- **Implementation**: See `BinaryProtocol.kt` with `getHeaderSize(version)` logic.
#### Use Cases for v2
- **Large Audio Files**: Professional recordings, podcasts, or music samples.
- **High-Resolution Images**: Full-resolution photos from modern smartphones.
- **Future File Types**: PDFs, documents, archives, or other large media.
#### Interoperability Requirements
- Clients receiving v2 packets must decode 4-byte `PayloadLength` fields.
- Clients sending file transfers should preferentially use v2 format.
- Fragmentation still applies: large files are split into fragments that fit within BLE MTU constraints (~128 KiB per fragment).
### 1.3 File Transfer TLV payload (BitchatFilePacket)
The file payload is a TLV structure with mixed length field sizes to support large contents efficiently.
- Defined in `app/src/main/java/com/bitchat/android/model/BitchatFilePacket.kt` (/Users/cc/git/bitchat-android/app/src/main/java/com/bitchat/android/model/BitchatFilePacket.kt)
Canonical TLVs (v2 spec):
- `0x01 FILE_NAME` — UTF8 bytes
- Encoding: `type(1) + len(2) + value`
- `0x02 FILE_SIZE` — 4 bytes (UInt32, bigendian)
- Encoding: `type(1) + len(2=4) + value(4)`
- Note: v1 used 8 bytes (UInt64). v2 standardizes to 4 bytes. See Legacy Compatibility below.
- `0x03 MIME_TYPE` — UTF8 bytes (e.g., `image/jpeg`, `audio/mp4`, `application/pdf`)
- Encoding: `type(1) + len(2) + value`
- `0x04 CONTENT` — raw file bytes
- Encoding: `type(1) + len(4) + value(len)`
- Exactly one CONTENT TLV per file payload in v2 (no TLVlevel chunking); overall packet fragmentation happens at the transport layer.
Encoding rules:
- Standard TLVs use `1 byte type + 2 bytes bigendian length + value`.
- CONTENT uses a 4byte bigendian length to allow payloads well beyond 64 KiB.
- With the v2 envelope (4byte payload length), CONTENT can be large; transport still fragments oversize packets to fit BLE MTU.
- Implementations should validate TLV boundaries; decoding should fail fast on malformed structures.
Decoding rules (v2):
- Accept the canonical TLVs above. Unknown TLVs should be ignored or cause failure per implementation policy (current Android rejects unknown types).
- FILE_SIZE expects `len=4` and is parsed as UInt32; receivers may upcast to 64bit internally.
- CONTENT expects a 4byte length field and a single occurrence; if multiple CONTENT TLVs are present, concatenate in order (defensive tolerance).
- If FILE_SIZE is missing, receivers may fall back to `content.size`.
- If MIME_TYPE is missing, default to `application/octet-stream`.
Legacy Compatibility (optional, for mixedversion meshes):
- FILE_SIZE (0x02): Some legacy senders used 8byte UInt64. Decoders MAY accept `len=8` and clamp to 32bit if needed.
- CONTENT (0x04): Legacy payloads might have used a 2byte TLV length with multiple CONTENT chunks. Decoders MAY support concatenating multiple CONTENT TLVs with 2byte lengths if encountered.

## 2) Fragmentation, Progress, and Cancellation
### 2.1 Fragmentation
File transfers reuse the mesh broadcasters fragmentation logic:
- `BluetoothPacketBroadcaster` checks if the serialized envelope exceeds the configured MTU and splits it into fragments via `FragmentManager`.
- Fragments are sent with a short interfragment delay (currently ~200 ms; matches iOS/Rust behavior notes in code).
- When only one fragment is needed, send as a single packet.
### 2.2 Transfer ID and progress events
We derive a deterministic transfer ID to track progress:
- `transferId = sha256Hex(packet.payload)` (hex string of the file TLV payload).
The broadcaster emits progress events to a shared flow:
- `TransferProgressManager.start(id, totalFragments)`
- `TransferProgressManager.progress(id, sent, totalFragments)`
- `TransferProgressManager.complete(id, totalFragments)`
The UI maps `transferId → messageId`, then updates `DeliveryStatus.PartiallyDelivered(sent, total)` as events arrive; when `complete`, switches to `Delivered`.
### 2.3 Cancellation
Transfers are cancellable midflight:
- The broadcaster keeps a `transferId → Job` map and cancels the job to stop sending remaining fragments.
- API path:
- `BluetoothPacketBroadcaster.cancelTransfer(transferId)`
- Exposed via `BluetoothConnectionManager.cancelTransfer` and `BluetoothMeshService.cancelFileTransfer`.
- `ChatViewModel.cancelMediaSend(messageId)` resolves `messageId → transferId` and cancels.
- UX: tapping the “X” on a sending media removes the message from the timeline immediately.

---
## 3) Receive Path and Persistence
Receiver dispatch is in `MessageHandler`:
- For both broadcast and private paths we try `BitchatFilePacket.decode(payload)`. If it decodes:
- The file is persisted under app files with typespecific subfolders:
- Audio: `files/voicenotes/incoming/`
- Image: `files/images/incoming/`
- Other files: `files/files/incoming/`
- Filename strategy:
- Prefer the transmitted `fileName` when present; sanitize path separators.
- Ensure uniqueness by appending `" (n)"` before the extension when a name exists already.
- If `fileName` is absent, derive from MIME with a sensible default extension.
- MIME determines extension hints (`.m4a`, `.mp3`, `.wav`, `.ogg` for audio; `.jpg`, `.png`, `.webp` for images; otherwise based on MIME or `.bin`).
- A synthetic chat message is created with content markers pointing to the local path:
- Audio: `"[voice] /abs/path/to/file"`
- Image: `"[image] /abs/path/to/file"`
- Other: `"[file] /abs/path/to/file"`
- `senderPeerID` is set to the origin, `isPrivate` set appropriately.

## 4) Sender Path
### 4.1 Audio (Voice Notes)
1) Capture
- Holdtorecord mic button starts `MediaRecorder` with AAC in MP4 (`audio/mp4`).
- Sample rate: 44100 Hz, channels: mono, bitrate: ~32 kbps (to reduce payload size for BLE).
- On release, we pad 500 ms before stopping to avoid clipping endings.
- Files saved under `files/voicenotes/outgoing/voice_YYYYMMDD_HHMMSS.m4a`.
2) Local echo
- We create a `BitchatMessage` with content `"[voice] <path>"` and add to the appropriate timeline (public/channel/private).
- For private: `messageManager.addPrivateMessage(peerID, message)`. For public/channel: `messageManager.addMessage(message)` or add to channel.
3) Packet creation
- Build a `BitchatFilePacket`:
- `fileName`: basename (e.g., `voice_… .m4a`)
- `fileSize`: file length
- `mimeType`: `audio/mp4`
- `content`: full bytes (ensure content ≤ 64 KiB; with chosen codec params typical short notes fit fragmentation constraints)
- Encode TLV; compute `transferId = sha256Hex(payload)`.
- Map `transferId → messageId` for UI progress.
4) Send
- Public: `BluetoothMeshService.sendFileBroadcast(filePacket)`.
- Private: `BluetoothMeshService.sendFilePrivate(peerID, filePacket)`.
- Broadcaster handles fragmentation and progress emission.
5) Waveform
- We extract a 120bin waveform from the recorded file (the same extractor used for the receiver) and cache by file path, so sender and receiver waveforms are identical.
Core files:
- `app/src/main/java/com/bitchat/android/ui/ChatViewModel.kt` (sendVoiceNote) (/Users/cc/git/bitchat-android/app/src/main/java/com/bitchat/android/ui/ChatViewModel.kt)
- `app/src/main/java/com/bitchat/android/model/BitchatFilePacket.kt` (/Users/cc/git/bitchat-android/app/src/main/java/com/bitchat/android/model/BitchatFilePacket.kt)
- `app/src/main/java/com/bitchat/android/mesh/BluetoothMeshService.kt` (/Users/cc/git/bitchat-android/app/src/main/java/com/bitchat/android/mesh/BluetoothMeshService.kt)
- `app/src/main/java/com/bitchat/android/features/voice/VoiceRecorder.kt` (/Users/cc/git/bitchat-android/app/src/main/java/com/bitchat/android/features/voice/VoiceRecorder.kt)
- `app/src/main/java/com/bitchat/android/features/voice/Waveform.kt` (cache + extractor) (/Users/cc/git/bitchat-android/app/src/main/java/com/bitchat/android/features/voice/Waveform.kt)
### 4.2 Images
1) Selection and processing
- System picker (Storage Access Framework) with `GetContent()` (`image/*`). No storage permission required.
- Selected image is downscaled so longest edge is 512 px; saved as JPEG (85% quality) under `files/images/outgoing/img_<timestamp>.jpg`.
- Helper: `ImageUtils.downscaleAndSaveToAppFiles(context, uri, maxDim=512)`.
2) Local echo
- Insert a message with `"[image] <path>"` in the current context (public/channel/private).
3) Packet creation
- Build `BitchatFilePacket` with mime `image/jpeg` and file content.
- Encode TLV + compute `transferId` and map to `messageId`.
4) Send
- Same paths as audio (broadcast/private), including fragmentation and progress emission.
Core files:
- `app/src/main/java/com/bitchat/android/features/media/ImageUtils.kt` (/Users/cc/git/bitchat-android/app/src/main/java/com/bitchat/android/features/media/ImageUtils.kt)

## 5) UI / UX Details
This section specifies exactly what users see and how inputs behave, so alternative clients can match the experience.
### 5.1 Message input area
- The input field remains mounted at all times to prevent the IME (keyboard) from collapsing during longpress interactions (recording). We overlay recording UI atop the text field rather than replacing it.
- While recording, the text caret (cursor) is hidden by setting a transparent cursor brush.
- Mentions and slash commands are styled with a monospace look and color coding.
Files:
- `app/src/main/java/com/bitchat/android/ui/InputComponents.kt` (/Users/cc/git/bitchat-android/app/src/main/java/com/bitchat/android/ui/InputComponents.kt)
### 5.2 Recording UX
- Hold the mic button to start recording. Recording runs until release, then we pad 500 ms and stop.
- While recording, a dense, realtime scrolling waveform overlays the input showing live audio; a timer is shown to the right.
- Component: `RealtimeScrollingWaveform` (dense bars, ~240 columns, ~20 FPS) in `app/src/main/java/com/bitchat/android/ui/media/RealtimeScrollingWaveform.kt`.
- The keyboard stays visible; the caret is hidden.
- On release, we immediately show a local echo message for the voice note and start sending.
### 5.3 Voice note rendering
- Displayed with a header (nickname + timestamp) then the waveform + controls row.
- Waveform
- A 120bin static waveform is rendered per file, identical for sender and receiver, extracted from the actual audio file.
- During send, the waveform fills left→right in blue based on fragment progress.
- During playback, the waveform fills left→right in green based on player progress.
- Controls
- Play/Pause toggle to the left of the waveform; duration text to the right.
- Cancel sending
- While sending a voice note, a round “X” cancel button appears to the right of the controls. Tapping cancels the transfer midflight.
Files:
- `app/src/main/java/com/bitchat/android/ui/MessageComponents.kt` (/Users/cc/git/bitchat-android/app/src/main/java/com/bitchat/android/ui/MessageComponents.kt)
- `app/src/main/java/com/bitchat/android/ui/media/WaveformViews.kt` (/Users/cc/git/bitchat-android/app/src/main/java/com/bitchat/android/ui/media/WaveformViews.kt)
- `app/src/main/java/com/bitchat/android/features/voice/Waveform.kt` (/Users/cc/git/bitchat-android/app/src/main/java/com/bitchat/android/features/voice/Waveform.kt)
### 5.4 Image sending UX
- A circular “+” button next to the mic opens the system image picker. After selection, we downscale to 512 px longest edge and show a local echo; the send begins immediately.
- Progress visualization
- Instead of a linear progress bar, we reveal the image blockbyblock (modemera homage).
- The image is divided into a constant grid (default 24×16), and the blocks are rendered in order based on fragment progress; there are no gaps between tiles.
- The cancel “X” button overlays the topright corner during sending.
- On cancel, the message is removed from the chat immediately.
Files:
- `app/src/main/java/com/bitchat/android/ui/media/ImagePickerButton.kt` (/Users/cc/git/bitchat-android/app/src/main/java/com/bitchat/android/ui/media/ImagePickerButton.kt)
- `app/src/main/java/com/bitchat/android/features/media/ImageUtils.kt` (/Users/cc/git/bitchat-android/app/src/main/java/com/bitchat/android/features/media/ImageUtils.kt)
- `app/src/main/java/com/bitchat/android/ui/media/BlockRevealImage.kt` (/Users/cc/git/bitchat-android/app/src/main/java/com/bitchat/android/ui/media/BlockRevealImage.kt)
- `app/src/main/java/com/bitchat/android/ui/MessageComponents.kt` (/Users/cc/git/bitchat-android/app/src/main/java/com/bitchat/android/ui/MessageComponents.kt)
### 5.5 Image receiving UX
- Received images render fully with rounded corners and are leftaligned like text messages.
- Tapping an image opens a fullscreen viewer with an option to save to the device Downloads via `MediaStore`.
Files:
- `app/src/main/java/com/bitchat/android/ui/media/FullScreenImageViewer.kt` (/Users/cc/git/bitchat-android/app/src/main/java/com/bitchat/android/ui/media/FullScreenImageViewer.kt)

## 5.6 Interactive Audio Features
### 5.6.1 Waveform Seeking
- Audio waveforms in chat messages are fully interactive: users can tap anywhere on the waveform to jump to that position in the audio playback.
- On tap, the seek position is calculated as a fraction of the waveform width (0.0 = beginning, 1.0 = end).
- This works for both playing and paused audio states.
- The MediaPlayer is seeked to the calculated position immediately, with visual feedback via progress bar update.
- Tapping provides precise control - e.g., tap 25% through waveform jumps to 25% through audio.
- No haptic feedback or visual indicator; the progress bar update serves as immediate feedback.
Waveform Canvas Implementation:
- `WaveformCanvas` uses `pointerInput` with `detectTapGestures` to capture tap events.
- Tap position is converted to a fraction: `position.x / size.width.toFloat()`.
- Clamped to 0.0-1.0 range for safety.
- `onSeek` callback is invoked with the calculated position fraction.
- Only enabled when `onSeek` is provided (disabled for sending in progress).
VoiceNotePlayer Seeking:
- Accepts position fraction (0.0-1.0) and converts to milliseconds: `seekMs = (position * durationMs).toInt()`.
- Calls `MediaPlayer.seekTo(seekMs)` to jump to the exact position.
- Updates progress state immediately for UI responsiveness even before playback reaches the new position.

- `app/src/main/java/com/bitchat/android/ui/MessageComponents.kt` (/Users/cc/git/bitchat-android/app/src/main/java/com/bitchat/android/ui/MessageComponents.kt) — VoiceNotePlayer with seekTo function
- `app/src/main/java/com/bitchat/android/ui/media/WaveformViews.kt` (/Users/cc/git/bitchat-android/app/src/main/java/com/bitchat/android/ui/media/WaveformViews.kt) — Interactive WaveformCanvas with tap handling
---
## 6) Edge Cases and Notes
- Filename collisions on receiver: prefer the sendersupplied name if present; always uniquify with a ` (n)` suffix before the extension to prevent overwrites.
- Path markers in messages
- We use simple content markers: `"[voice] <abs path>", "[image] <abs path>", "[file] <abs path>"` for local rendering. These are not sent on the wire; the actual file bytes are inside the TLV payload.
- Progress math for images relies on `(sent / total)` from `TransferProgressManager` (fragmentlevel granularity). The block grid density can be tuned; currently 24×16.
- Private vs public: both use the same file TLV; only the envelope `recipientID` differs. Private may have signatures; code shows a signing step consistent with iOS behavior prior to broadcast to ensure integrity.
- BLE timing: there is a 200 ms interfragment delay for stability. Adjust as needed for your radio stack while maintaining compatibility.

## 8) Implementation Checklist for Other Clients
1. **Implement v2 protocol support**: Support both v1 (2-byte payload length) and v2 (4-byte payload length) packet decoding. Use v2 format for file transfer packets to enable large file transfers.
2. Implement `BitchatFilePacket` TLV exactly as specified:
- FILE_NAME and MIME_TYPE: `type(1) + len(2) + value`
- FILE_SIZE: `type(1) + len(2=4) + value(4, UInt32 BE)`
- CONTENT: `type(1) + len(4) + value`
3. Embed the TLV into a `BitchatPacket` envelope with `type = FILE_TRANSFER (0x22)` and the correct `recipientID` (broadcast vs private).
4. Fragment, send, and report progress using a transfer ID derived from `sha256(payload)` so the UI can map progress to a message.
5. Support cancellation at the fragment sender: stop sending remaining fragments and propagate a cancel to the UI (we remove the message).
6. On receive, decode TLV, persist to an app directory (separate audio/images/other), and create a chat message with content marker `"[voice] path"`, `"[image] path"`, or `"[file] path"` for local rendering.
7. Audio sender and receiver should use the same waveform extractor so visuals match; a 120bin histogram is a good balance.
8. **Implement interactive waveform seeking**: Tap waveforms to jump to that audio position. Calculate tap position as fraction (0.0-1.0) of waveform width.
9. For images, optionally downscale to keep TLV small; JPEG 85% at 512 px longest edge is a good baseline.
10. Mirror the UX:
- Recording overlay that does not collapse the IME; hide the caret while recording; add 500 ms end padding.
- Voice: waveform fill for send/playback; cancel overlay; **tap-to-seek support**.
- Images: dense blockreveal with no gaps during sending; cancel overlay; fullscreen viewer with save.
- Generic files: render as a file pill with icon + filename; support open/save via the host OS.
Following the above should produce an interoperable and matching experience across platforms.

# GCS Filter Sync (REQUEST_SYNC)
This document specifies the gossip-based synchronization feature for BitChat, inspired by Plumtree. It ensures eventual consistency of public packets (ANNOUNCE and broadcast MESSAGE) across nodes via periodic sync requests containing a compact GolombCoded Set (GCS) of recently seen packets.
## Overview
- Each node maintains a rolling set of public BitChat packets it has seen recently:
- Broadcast messages (MessageType.MESSAGE where recipient is broadcast)
- Identity announcements (MessageType.ANNOUNCE)
- Default retention is 100 recent packets (configurable in the debug sheet). This value is the maximum number of packets that are synchronized per request (across both types combined).
- Nodes do not maintain a rolling Bloom filter. Instead, they compute a GCS filter on demand when sending a REQUEST_SYNC.
- Every 30 seconds, a node sends a REQUEST_SYNC packet to all immediate neighbors (local only; not relayed).
- Additionally, 5 seconds after the first announcement from a newly directly connected peer is detected, a node sends a REQUEST_SYNC only to that peer (unicast; local only).
- The receiver checks which packets are not in the senders filter and sends those packets back. For announcements, only the latest announcement per peerID is sent; for broadcast messages, all missing ones are sent.
This synchronization is strictly local (not relayed), ensuring only immediate neighbors participate and preventing wide-area flooding while converging content across the mesh.
## Packet ID
To compare packets across peers, a deterministic packet ID is used:
- ID = first 16 bytes of SHA-256 over: [type | senderID | timestamp | payload]
- This yields a 128-bit ID used in the filter.
Implementation: `com.bitchat.android.sync.PacketIdUtil`.
## GCS Filter (On-demand)
Implementation: `com.bitchat.android.sync.GCSFilter`.
- Parameters (configurable):
- size: 1281024 bytes (default 256)
- target false positive rate (FPR): default 1% (range 0.1%5%)
- Derivations:
- P = ceil(log2(1/FPR))
- Maximum number of elements that fit into the filter is estimated as: N_max ≈ floor((8 * sizeBytes) / (P + 2))
- This estimate is used to cap the set; the actual encoder will trim further if needed to stay within the configured size.
- What goes into the set:
- Combine the following and sort by packet timestamp (descending):
- Broadcast messages (MessageType 1)
- The most recent ANNOUNCE per peer
- Take at most `min(N_max, maxPacketsPerSync)` items from this ordered list.
- Compute the 16-byte Packet ID (see below), then for hashing use the first 8 bytes of SHA256 over the 16byte ID.
- Map each hash to [0, M) with M = N * 2^P; sort ascending and encode deltas with GolombRice parameter P.
Hashing scheme (fixed for crossimpl compatibility):
- Packet ID: first 16 bytes of SHA256 over [type | senderID | timestamp | payload].
- GCS hash: h64 = first 8 bytes of SHA256 over the 16byte Packet ID, interpreted as an unsigned 64bit integer. Value = h64 % M.
## REQUEST_SYNC Packet
MessageType: `REQUEST_SYNC (0x21)`
- Header: normal BitChat header with TTL indicating “local-only” semantics. Implementations SHOULD set TTL=0 to prevent any relay; neighbors still receive the packet over the direct link-layer. For periodic sync, recipient is broadcast; for per-peer initial sync, recipient is the specific peer.
- Payload: TLV with 16bit bigendian length fields (type, length16, value)
- 0x01: P (uint8) — GolombRice parameter
- 0x02: M (uint32) — hash range N * 2^P
- 0x03: data (opaque) — GCS bitstream (MSBfirst bit packing)
Notes:
- The GCS bitstream uses MSBfirst packing (bit 7 is the first bit in each byte).
- Receivers MUST reject filters with data length exceeding the local maximum (default 1024 bytes) to avoid DoS.
Encode/Decode implementation: `com.bitchat.android.model.RequestSyncPacket`.
## Behavior
Sender behavior:
- Periodic: every 30 seconds, send REQUEST_SYNC with a freshly computed GCS snapshot, broadcast to immediate neighbors, and mark as localonly (TTL=0 recommended; do not relay).
- Initial per-peer: upon receiving the first ANNOUNCE from a new directly connected peer, send a REQUEST_SYNC only to that peer after ~5 seconds (unicast; TTL=0 recommended; do not relay).
Receiver behavior:
- Decode the REQUEST_SYNC payload and reconstruct the sorted set of mapped values using the provided P, M, and bitstream.
- For each locally stored public packet ID:
- Compute h64(ID) % M and check if it is in the reconstructed set; if NOT present, send the original packet back with `ttl=0` to the requester only.
- For announcements, send only the latest announcement per (sender peerID).
- For broadcast messages, send all missing ones.
Announcement retention and pruning (consensus):
- Store only the most recent announcement per peerID for sync purposes.
- Age-out policy: announcements older than 60 seconds MUST be removed from the sync candidate set.
- Pruning cadence: run pruning every 15 seconds to drop expired announcements.
- LEAVE handling: upon receiving a LEAVE message from a peer, immediately remove that peers stored announcement from the sync candidate set.
- Stale/offline peer handling: when a peer is considered stale/offline (e.g., last announcement older than 60 seconds), immediately remove that peers stored announcement from the sync candidate set.
Important: original packets are sent unmodified to preserve original signatures (e.g., ANNOUNCE). They MUST NOT be relayed beyond immediate neighbors. Implementations SHOULD send these response packets with TTL=0 (local-only) and, when possible, route them only to the requesting peer without altering the original packet contents.
## Scope and Types Included
Included in sync:
- Public broadcast messages: `MessageType.MESSAGE` with BROADCAST recipient (or null recipient).
- Identity announcements: `MessageType.ANNOUNCE`.
- Both packets produced by other peers and packets produced by the requester itself MUST be represented in the requesters GCS; the responder MUST track and consider its own produced public packets as candidates to return when they are missing on the requester.
- Announcements included in the GCS MUST be at most 60 seconds old at the time of filter construction; older announcements are excluded by pruning.
Not included:
- Private messages and any packets addressed to a non-broadcast recipient.
## Configuration (Debug Sheet)
Exposed under “sync settings” in the debug settings sheet:
- Max packets per sync (default 100)
- Max GCS filter size in bytes (default 256, min 128, max 1024)
- GCS target FPR in percent (default 1%, 0.1%5%)
- Derived values (display only): P and the estimated maximum number of elements that fit into the filter.
Backed by `DebugPreferenceManager` getters and setters:
- `getSeenPacketCapacity` / `setSeenPacketCapacity`
- `getGcsMaxFilterBytes` / `setGcsMaxFilterBytes`
- `getGcsFprPercent` / `setGcsFprPercent`
## Android Integration
- New/updated types and classes:
- `MessageType.REQUEST_SYNC` (0x21) in `BinaryProtocol.kt`
- `RequestSyncPacket` in `model/RequestSyncPacket.kt`
- `GCSFilter` and `PacketIdUtil` in `sync/`
- `GossipSyncManager` in `sync/`
- `BluetoothMeshService` wires and starts the sync manager, schedules per-peer initial (unicast) and periodic (broadcast) syncs, and forwards seen public packets (including our own) to the manager.
- `PacketProcessor` handles REQUEST_SYNC and forwards to `BluetoothMeshService` which responds via the sync manager with responses targeted only to the requester.
## Compatibility Notes
- GCS hashing and TLV structures are fully specified above; other implementations should use the same hashing scheme and payload layout for interoperability.
- REQUEST_SYNC and responses are local-only and MUST NOT be relayed. Implementations SHOULD use TTL=0 to prevent relaying. If an implementation requires TTL>0 for local delivery, it MUST still ensure that REQUEST_SYNC and responses are not relayed beyond direct neighbors (e.g., by special-casing these types in relay logic).
## Consensus vs. Configurable
The following items require consensus across all implementations to ensure interoperability:
- Packet ID recipe: first 16 bytes of SHA256(type | senderID | timestamp | payload).
- GCS hashing function and mapping to [0, M) as specified above (v1), and MSBfirst bit packing for the bitstream.
- Payload encoding: TLV with 16bit bigendian lengths; TLV types 0x01 = P (uint8), 0x02 = M (uint32), 0x03 = data (opaque).
- Packet type and scope: REQUEST_SYNC = 0x21; local-only (not relayed); only ANNOUNCE and broadcast MESSAGE are synchronized; ANNOUNCE dedupe is “latest per sender peerID”.
The following are requesterdefined and communicated or local policy (no global agreement required):
- GCS parameters: P and M are carried in the REQUEST_SYNC and must be used by the receiver for membership tests. The sender chooses size and FPR; receivers MUST cap accepted data length for DoS protection.
- Local storage policy: how many packets to consider and how you determine the “latest” announcement per peer.
- Sync cadence: how often to send REQUEST_SYNC and initial delay after new neighbor connection; whether to use unicast for initial per-peer sync versus broadcast for periodic sync. The number of packets included is bounded by the debug setting and filter capacity.
Validation and limits (recommended):
- Reject malformed REQUEST_SYNC payloads (e.g., P < 1, M <= 0, or data length too large for local limits).
- Practical bounds: data length in [0, 1024]; P in [1, 24]; M up to 2^321.
Versioning:
- This document defines a fixed GCS hashing scheme (“v1”) with no explicit version field in the payload. Changing the hashing or ID recipe would require a new message or an additional TLV in a future revision; current deployments must adhere to the constants above.
