SP110E peripherals silently tear down the GATT link ~1s after connect
unless a two-write vendor handshake (01 00 → FFE2, 01 B7 E3 D5 → FFE1)
arrives immediately. Without it the first real write hangs 30s then
reconnect-loops forever. Adds optional BLEProtocol.init_writes executed
on connect, plumbs a per-write char_uuid through both transports, and
fixes the SP110E color/power frames from an incorrect 5 bytes to the
documented 4 bytes.
Windows/WinRT robustness:
- asyncio.wait_for hangs on bleak because WinRT IAsyncOperations refuse
to cancel. _bounded_await() uses asyncio.wait() instead so timeouts
actually return control even when the inner task is uncancellable.
- BleakClient connect by raw MAC string times out when WinRT guesses
address type wrong; switched to pre-scanning with BleakScanner and
passing the resolved BLEDevice, which carries the address type.
- Target-start fetch timeout bumped to 30s with retry disabled so the
UI doesn't abort during the BLE pre-scan + connect + handshake path.
UI:
- Settings modal exposes Protocol Family (IconSelect grid, shared with
add-device via parameterized ensureBleFamilyIconSelect) so users can
fix a wrong family pick without recreating the device. Govee AES key
row toggles on/off with family selection.
Also turns LAN auth back on in default_config.yaml, logs start_processing
requests on entry for easier diagnosis, and captures the full debug trail
in docs/BLE_LED_CONTROLLERS.md for future BLE work.
