Add Windows GUI support with system tray interface#7
Conversation
- Created src/core/ with platform-agnostic bridge components: - bridge.py: Main orchestrator - ble_handler.py: BLE connection management - tcp_handler.py: TCP server handling - cache_manager.py: Config caching system - protocol.py: TCP frame handling - stats.py: Real-time statistics tracking - Created src/cli/ for CLI interface maintaining backward compatibility - Updated Dockerfile to use new module structure - Bumped version to 2.0.0 to indicate major refactoring This refactoring prepares for Windows GUI support while maintaining existing Linux/Docker functionality. All logic is now shared between platform-specific interfaces (CLI for Linux, GUI for Windows). Related to: Windows support implementation
Implemented complete Windows GUI application (Phase 2): GUI Components (src/gui/): - main.py: GUI entry point with logging setup - tray_app.py: System tray application with pystray * Green/gray icon for connected/disconnected states * Menu: Status, Settings, Connect/Disconnect, Scan, View Logs, Exit * Async event loop integration with bridge * Config persistence to JSON * Real-time statistics updates - settings_dialog.py: Configuration UI with tkinter * BLE MAC address with validation * TCP port configuration * Cache settings (enable/disable, max nodes) * Auto-connect on startup * Input validation and user-friendly error messages Build System (build/windows/): - build.spec: PyInstaller configuration * Single-file executable * No console window (GUI mode) * UPX compression * Excludes unnecessary modules (numpy, scipy, etc.) - build.ps1: PowerShell build script * Dependency installation * Clean build process * Build verification and size reporting - README.md: Build instructions and troubleshooting Documentation: - docs/WINDOWS_GUI.md: Comprehensive Windows user guide * Quick start guide * Feature overview * Tray menu reference * Troubleshooting section * Comparison with Linux Docker version - README.md: Updated with platform support table and Windows quick start Dependencies: - requirements-gui.txt: GUI-specific dependencies * pystray: System tray support * Pillow: Icon generation * pywin32: Windows integration (optional) Features: ✅ System tray icon with visual status (green=connected, gray=disconnected) ✅ Configuration dialog with all bridge settings ✅ Device scanning from GUI ✅ Real-time statistics display ✅ Log file viewer (Notepad integration) ✅ Notifications for connection events ✅ Auto-connect on startup (optional) ✅ Clean shutdown handling The GUI shares the same core bridge logic as the CLI/Docker version, ensuring feature parity across platforms. Icons are generated programmatically (no external assets required). Related to: #windows-support
GitHub Actions Workflows (Phase 3):
1. release-windows.yml (NEW):
- Builds Windows executable on release
- Uses PyInstaller with build.spec
- Creates ZIP archive with versioned name
- Uploads to GitHub releases as asset
- Generates SHA256 checksum
- Supports manual workflow_dispatch trigger
- Build summary with size and platform info
2. test.yml (UPDATED):
- Multi-platform testing (Ubuntu + Windows)
- Test matrix: Python 3.9-3.12 on both platforms
- Separate jobs for:
* Core module tests (both platforms)
* CLI imports test (Linux)
* GUI imports test (Windows)
* Docker build test (Linux)
- Coverage reporting (Ubuntu, Python 3.11 only)
- Runs on feature branches for CI feedback
3. docker-release.yml (UNCHANGED):
- Already supports new src/ structure
- Multi-arch builds (amd64, arm64, arm/v7)
- Triggered on release publication
Features:
✅ Parallel Windows + Docker releases
✅ Cross-platform test coverage
✅ Automated version extraction from git tags
✅ Build artifact retention (30 days)
✅ Checksum generation for security
✅ Pip caching for faster builds
✅ Docker layer caching for efficiency
The workflows enable fully automated releases:
- Tag a release → Both Windows .exe and Docker images built
- PR to main → Tests run on both Linux and Windows
- Feature branches → CI feedback on all platforms

pystray requires a display which isn't available in GitHub Actions. Changed test to import settings_dialog and main module instead of TrayApplication which initializes pystray. This verifies the GUI dependencies are installed and importable without requiring a display server.

Pull Request Review: Windows GUI SupportThis PR adds comprehensive Windows GUI support while maintaining backward compatibility. The refactoring is well-executed with several areas for improvement. Critical Issues1. Race Condition in Bridge Startup (src/gui/tray_app.py:280)Severity: High The _start_bridge() method calls await self.bridge.start() but NEVER calls serve_forever(). The TCP server won't accept connections. The GUI will appear connected but fail to handle TCP clients. Fix: Add this after bridge.start(): 2. Unsafe Thread-Event Loop Interaction (src/gui/tray_app.py:240)Severity: Medium-High Reconnect fires without error handling. UI won't know if it fails. Strengths

Create thread-safe messagebox wrapper to prevent GUI freezes: - Add _show_messagebox_safe() function that properly creates/destroys Tk root - Replace all tk.Tk() and messagebox calls with safe wrapper - Add topmost attribute to ensure dialogs appear in front - Properly call quit() before destroy() to clean up event loop This fixes the issue where popups would get stuck and couldn't be closed. The problem was multiple Tk instances being created from different threads without proper cleanup, causing tkinter's event loop to lock up. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

The SettingsDialog.show() calls mainloop() which was blocking the pystray menu thread and causing the UI to freeze. Users couldn't type in the dialog or close it. Solution: - Create settings dialog in a separate thread - Add _show_settings_threaded() method to run dialog.show() - Use daemon=False to ensure dialog completes before app exit This allows the pystray menu to remain responsive while the settings dialog is open.

Settings Dialog Issues: - Validation error messageboxes were using messagebox directly - Added thread-safe _show_error wrapper in settings_dialog.py - Replaced transient() and grab_set() with simpler topmost approach - All validation errors now use safe wrapper Async Error Dialog Issues: - Error dialogs from async threads (like _start_bridge) were locking up - Enhanced _show_messagebox_safe to detect thread context - If called from non-main thread, spawns dedicated thread and waits - Prevents tkinter threading conflicts This fixes: 1. Settings dialog not saving (validation errors were blocking) 2. "Configuration Required" error dialog freezing and not closing 3.

Some Meshtastic devices have emoji in their names (e.g., 🏎_a938). Windows console uses cp1252 encoding by default, which can't encode these characters, causing crashes during device scanning. Fixes: - Set encoding='utf-8' on all FileHandler instances - Configure StreamHandler to use UTF-8 with errors='replace' fallback - Applied to both gui/main.py and gui/tray_app.py logging setup This allows the app to log device names with emoji without crashing.

The Status dialog and other messageboxes were locking up because we were calling root.quit() without running root.mainloop(). The quit() method is meant to stop a running event loop, but messagebox.showinfo() already blocks synchronously until the user closes it. Calling quit() on a non-running loop caused the window to become unresponsive. Fixes: - Removed root.quit() from _show_messagebox_safe in tray_app.py - Removed root.quit() from _show_error in settings_dialog.py - Added root.lift() and root.focus_force() to ensure dialogs appear - Added clarifying comments about not needing quit() without mainloop This fixes the Status dialog lockup and any other messagebox freezing issues.

When cache pre-warming fails due to Windows BLE authentication requirements (Protocol Error 0x05), provide helpful guidance. Changes: - Detect authentication/pairing errors specifically - Show user-friendly message with pairing instructions - Clarify that bridge continues to work without cache - Note that reconnections will be slower without cache The bridge works fine without caching - it just means reconnections take 30s+ instead of 100ms. Users can pair the device in Windows Settings to enable caching. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

When a device reboots, the bridge detects disconnection and reconnects.
However, during reconnection TCP clients continue sending packets, which
caused errors because BLE characteristics weren't ready yet.
Fixes:
1. Added services_ready flag to track when GATT services are available
2. Set services_ready=True only after service discovery completes
3. Set services_ready=False on disconnect
4. Check services_ready before allowing sends (prevents premature writes)
5. Check is_reconnecting flag before allowing sends
6. Detect "characteristic not found" errors and trigger reconnection
7. Suppress error logs for expected reconnection states (debug only)
8. Drop TCP packets gracefully during reconnection
This eliminates the spam of "Characteristic {char_specifier} was not found!"
errors during device reboots. The bridge now properly waits for services
to be ready before allowing writes.

User feedback confirmed that Windows BLE pairing is required for ALL operations, not just cache pre-warming. Updated UI and docs to make this clear. Settings Dialog: - Added prominent warning box at top of Settings - "IMPORTANT: Device must be paired in Windows first!" - Shows pairing path: Settings → Bluetooth & devices → Add device - Orange text with border to draw attention Documentation: - Updated WINDOWS_GUI.md with "REQUIRED" in heading - Added explanation of why pairing is needed - Updated README.md Windows Quick Start section - Made pairing a clear prerequisite step Log Messages: - Updated cache pre-warming error to say "REQUIRED" - Removed misleading "optional" language This clarifies that pairing is the first mandatory step before using the bridge on Windows.

Critical fixes for device reconnection after reboot: 1. Prevent duplicate polling loops - Added _initial_connect flag to track first vs reconnect - Only start polling task on initial connect, not during reconnection - Prevents multiple concurrent polling loops from competing 2. Improved reconnection state management - Double-check is_reconnecting before acquiring lock to prevent races - Set running=False when polling exits after failed reconnection - Reset all state flags in disconnect() for clean next connection - Added debug logging when resuming polling after reconnection 3. Increased service discovery timeout - Raised from 10s to 20s to handle Windows BLE delays after device reboot - Better handles the time needed for Windows to re-enumerate services 4. Better .gitignore coverage - Added **/__pycache__/ to cover all Python cache directories - Added .serena/ for MCP server state This fixes the issue where reconnection would succeed but immediately trigger another reconnection attempt, causing "Device not found" errors and eventual polling loop exit.

Code Review: PR #7 - Windows GUI SupportOverviewThis PR successfully adds Windows system tray GUI support with a clean refactoring into core modules. The architecture is solid, but there are several critical issues that should be addressed before merging. 🔴 Critical Issues1. Race Condition in BLE Disconnect HandlerLocation: asyncio.create_task(self.on_disconnected()) # Fire-and-forget - NOT GOODProblem: The task is created but never tracked or awaited. If the callback raises an exception, it's silently lost. The bridge may think it's reconnecting when it's actually failed. Fix: Track the task or handle exceptions: task = asyncio.create_task(self.on_disconnected())
self._disconnect_tasks.append(task)
# Or add exception handling in the callback2. Multiple Event Loops Without CoordinationLocations:
Problem: Two independent event loops in different threads can cause deadlocks and race conditions when passing data between them. Fix: Use a single event loop. For the settings dialog scan: # Instead of creating new loop, use the existing bridge loop
future = asyncio.run_coroutine_threadsafe(scan_devices(), bridge_loop)
results = future.result(timeout=30)3. Event Loop Destroyed While Operations RunningLocation: loop.close() # May close while scan_devices() still has network I/O!Problem: The loop is closed immediately after running scan, but BLE scanning involves async network operations that may not be complete. Fix: Properly await all tasks before closing: pending = asyncio.all_tasks(loop)
loop.run_until_complete(asyncio.gather(*pending, return_exceptions=True))
loop.close()🟡 High Priority Issues4. GUI Thread BlockingLocation: subprocess.run(['notepad.exe', str(log_file)]) # Blocks GUI!Problem: This blocks the entire system tray while Notepad is open. Fix: Use non-blocking Popen: subprocess.Popen(['notepad.exe', str(log_file)])5. TCP Connection Memory LeakLocation: Problem: The Fix: Add connection timeout tracking: self.client_timeouts: Dict[asyncio.StreamWriter, float] = {}
# Periodically check and close idle connections (>30s)6. Unsafe Thread-to-Async CallsLocation: asyncio.run_coroutine_threadsafe(self._restart_bridge(), self.loop)Problem: No error handling if the loop has crashed or stopped. Fix: Check the result: future = asyncio.run_coroutine_threadsafe(self._restart_bridge(), self.loop)
try:
future.result(timeout=5.0)
except Exception as e:
logger.error(f"Bridge operation failed: {e}")
self._show_error("Bridge Error", str(e))🟢 Medium Priority Issues7. Inefficient Cache Node CountingLocation: Problem: Iterates entire cache and parses every protobuf to count nodes on each add operation - O(n) performance. Fix: Track node count separately: self.node_count = 0 # Track incrementally
# Update in add_packet() instead of parsing cache8. Import Inside LoopLocation: import time # Inside _poll_from_radio which runs every 100msFix: Move to module level (top of file). 9. Config File PermissionsLocation: Problem: Config file created with default permissions (potentially world-readable). Fix: Set restrictive permissions: import stat
config_file.parent.mkdir(parents=True, exist_ok=True)
config_file.parent.chmod(stat.S_IRWXU) # 0o70010. No Code SigningLocation: Problem: Windows executable isn't code-signed, will show "Unknown Publisher" warning. Recommendation: Add Authenticode signing step (requires certificate): - name: Sign executable

The disconnect callback triggers bridge's reconnection handler, while the polling loop also independently detects the disconnect. Both try to reconnect, but the polling loop was only waiting 1 second before giving up, while the callback-triggered reconnection was in its 2s initial delay. Fix: Make polling loop properly wait (up to 60s) for the callback- triggered reconnection to complete by monitoring the is_reconnecting flag instead of just sleeping for 1 second. This prevents the "Failed to reconnect, exiting polling loop" error that occurs while the actual reconnection is still in progress. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

When device reboots, the old logic wasted too much time: - Initial connect: 20s + disconnect-retry: 5s + sleep: 2s + retry: 20s = 47s - Service discovery: 20s - Total per attempt: 67s This caused the polling loop to timeout at 60s while reconnection was still in progress. New approach: - During reconnection (not initial connect): - Fast fail with 15s connection timeout (no disconnect-retry) - Fast fail with 10s service discovery timeout - Total per attempt: ~25s - Let exponential backoff handle retries across attempts - Polling loop waits up to 200s for all 5 attempts This allows the bridge to try reconnecting 5 times with exponential backoff (2s, 4s, 8s, 16s, 32s delays) before giving up, while each individual attempt fails fast if the device isn't ready yet.

The bridge's disconnect handler was only calling attempt_reconnection() ONCE and then giving up. The reconnect counter and exponential backoff logic in attempt_reconnection() was designed for multiple calls, but nobody was making those calls. Now the bridge loops up to MAX_RECONNECT_ATTEMPTS (5) times, calling attempt_reconnection() for each retry. This gives the device time to reboot and become available again: Attempt 1: Wait 2s, try connect (15s timeout) Attempt 2: Wait 4s, try connect (15s timeout) Attempt 3: Wait 8s, try connect (15s timeout) Attempt 4: Wait 16s, try connect (15s timeout) Attempt 5: Wait 32s, try connect (15s timeout) Total time: ~142s across all attempts The polling loop waits up to 200s for this to complete.

The polling loop was calling attempt_reconnection() and giving up after the first attempt failed, even though the bridge's disconnect handler was still trying attempts 2-5. This caused the polling loop to exit while reconnection was still in progress. Timeline of the bug: 13:45:29 - Disconnect callback starts attempt 1 13:45:29 - Polling loop calls attempt_reconnection() 13:45:29 - Polling loop waits for is_reconnecting to clear 13:45:48 - Attempt 1 fails, is_reconnecting = False 13:45:48 - Polling loop wakes up, sees failure, EXITS 13:45:48 - Bridge starts attempt 2 (but polling loop is dead!) Fix: Polling loop now passively waits up to 250 seconds, checking connection status every second. It doesn't call attempt_reconnection() at all - just lets the bridge's disconnect handler do all 5 attempts while it waits patiently. When reconnection succeeds (any attempt 1-5), polling loop sees is_connected = True and resumes. If all attempts fail, it exits. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

Windows BLE caches device availability state. After a device reboots, Windows may still think the device is unavailable even when it comes back online. This causes connection attempts to fail even when the device is actually ready. Fix: Before each reconnection attempt, actively scan for the device with a 5-second timeout. This forces Windows to refresh its cache of available devices. Benefits: - Fails fast (~5s) when device not visible in scan - Only attempts connection when device is actually discoverable - Refreshes Windows BLE cache to see newly-rebooted devices Timeline now: - Attempt 1: Scan 5s → Device not found → Fail fast (~5s) - Attempt 2: Scan 5s → Device not found → Fail fast (~5s) - Attempt 3: Scan 5s → Device not found → Fail fast (~5s) - Attempt 4: Scan 5s → Device found! → Connect → Success ✅ Much faster than waiting 15s per attempt when device isn't ready.

1. Increase max reconnection attempts from 5 to 10 - Meshtastic devices can take 2+ minutes to fully reboot - With exponential backoff, this gives up to ~6 minutes total 2. Properly clean up old BLE client before reconnecting - Set self.client = None to release Python object - Sleep 1s to let Windows release BLE resources - This was THE critical bug - old connection was blocking new one 3. Increase scan timeout from 5s to 10s during reconnection - Windows BLE can be slow to rediscover rebooted devices - Longer scan gives Windows more time to refresh cache 4. Update polling loop wait time to 600s (10 minutes) - Allows all 10 reconnection attempts to complete The key insight: Windows holds onto BLE connection state even after disconnect(). We must fully release the old BleakClient object and give Windows time to clean up before creating a new connection. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

After successful reconnection, the bridge was only re-initializing the device connection if cache was enabled (via cache.prewarm()). With cache disabled, the bridge would reconnect but never request device configuration, leaving the connection idle. Now after reconnection, regardless of cache setting: - Send want_config_id request to device - Device responds with all config, nodes, channels, etc. - Data flows to TCP clients This ensures MeshMonitor (or any TCP client) can continue working after a device reboot, even with caching disabled.

When creating BleakClient during reconnection, we were passing just the MAC address string. Windows BLE may have stale cached information for that address, causing connection failures even when the device is actually available. Now we: 1. Scan for the device (refreshes Windows cache) 2. Save the discovered device object from the scan 3. Create BleakClient using the device object (not MAC string) This ensures we're connecting to the fresh device object with current BLE metadata, not stale cached data.

- Removed console window (build.spec: console=False) - Added error state (red icon) for reconnection failure - Added register_failure_callback() to bridge - Added _on_reconnection_failed() to tray app - Verified Docker build still works Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Code Review - PR #7: Windows GUI SupportThis is a substantial and well-structured PR that successfully adds Windows support while maintaining backward compatibility. Overall, the code quality is high, but there are several areas that need attention before merging. 🎯 SummaryStrengths:
Priority Issues:
🔴 Critical Issues1. Security: Plaintext Config Storage (src/gui/tray_app.py:146)The configuration file stores BLE MAC addresses and settings in plaintext JSON without any encryption: with open(config_file, 'w') as f:
json.dump(self.config, f, indent=2)Impact: While BLE MAC addresses are not highly sensitive, storing configuration in plaintext in user home directories can expose network topology and device information. Recommendation: Consider using Windows DPAPI for encrypting sensitive configuration data, especially if you plan to store any authentication tokens in the future. 2. Security: Command Injection in Log Viewer (src/gui/tray_app.py:388)The log viewer opens files using subprocess without proper validation: subprocess.run(['notepad.exe', str(log_file)])Impact: While Recommendation: Use import os
os.startfile(str(log_file))3. Resource Leak: Unclosed Tkinter Windows (src/gui/settings_dialog.py:21, tray_app.py:60)Multiple locations create Tkinter root windows that may not be properly destroyed in error scenarios: root = tk.Tk()
root.withdraw()
# ... operations that might fail ...
root.destroy() # May not be reached if exception occursRecommendation: Use context managers or try-finally blocks consistently.

Pull Request Review: Windows GUI SupportSummaryThis is a substantial and well-executed PR that adds native Windows support with a polished GUI while maintaining full backward compatibility with the existing Linux/Docker CLI. The code demonstrates strong architectural principles with proper separation of concerns, good error handling, and thoughtful user experience design. Overall Assessment: ✅ Approve with minor suggestions Strengths1. Excellent Architecture ⭐⭐⭐⭐⭐The refactoring into a modular core is exemplary:
2. Robust BLE Reconnection Logic ⭐⭐⭐⭐⭐The reconnection handling is sophisticated and production-ready:
3. User Experience Polish ⭐⭐⭐⭐
4. Comprehensive Testing ⭐⭐⭐⭐
Critical Issues 🔴1. Security: Configuration File PermissionsLocation: src/gui/tray_app.py:140-149 The configuration file lacks permission restrictions. On shared Windows systems, this file is world-readable. Fix: Add file permission restrictions (chmod 0600). 2. Test Suite Import MismatchLocation: src/test_ble_tcp_bridge.py:15 Tests import the old monolithic module but architecture was refactored. Tests reference attributes that don't exist:
Fix: Update tests to use new module structure. Major Concerns 🟡3. Missing Input Validation in Settings DialogUsers could enter invalid values:
Fix: Add bounds checking for numeric inputs (port 1024-65535, cache nodes 10-5000). 4. Potential Race Condition in Stats UpdatesStats callbacks invoked from async contexts without synchronization. Fix: Add async lock to StatsCollector. 5. Hardcoded Reconnection AttemptsMAX_RECONNECT_ATTEMPTS = 10 is hardcoded. Fix: Make configurable via bridge constructor. 6. Memory Leak Risk in Long-Running CacheCache grows indefinitely on runtime additions. Size limit only enforced during prewarm. Fix: Call _enforce_size_limit() after runtime cache additions.
