In-container BLE reconnection is unreliable because bleak leaves stale GATT notification handles after abnormal disconnect, and adapter power- cycling from within Docker corrupts bleak's internal BlueZ manager state. New approach: - On BLE disconnect or keepalive failure, immediately mark as permanently failed (no in-container reconnect attempts) - Health endpoint returns 503, Docker healthcheck triggers container restart - Docker entrypoint script disconnects stale BLE connections before app starts, ensuring clean GATT state for bleak This is reliable because: - MeshCore.create_ble(address=...) works on fresh container starts - The BlueZ daemon on the host maintains adapter state correctly - Container restart is fast (~5s) and gives a truly clean BLE state Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
