- Add missing addEventListener/removeEventListener mocks in BLEContext cleanup tests
- Fix scanning simulation by calling scanDevices() instead of trying to set state directly
- Add explicit timeouts to bulkSetWiFi tests (10-15s) to accommodate MockBLEManager delays
- Update concurrent connection error message check to match actual error text
All 42 BLE tests now pass (36 bulk/concurrent + 6 cleanup)
Prevents race conditions when multiple connection attempts are made
to the same device simultaneously by:
- Adding connectingDevices Set to track in-progress connections
- Checking for concurrent connections before starting new attempt
- Returning early if device is already connected
- Using finally block to ensure cleanup of connecting state
- Clearing connectingDevices set on cleanup
Includes comprehensive test suite for concurrent connection scenarios
including edge cases like rapid connect/disconnect cycles and cleanup
during connection attempts.
