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.
