BtCarKey: reconstructing a BLE car-key box client

BtCarKey implements an Android client for a keyless car box using a reconstructed FTK BLE interface. Its protocol notes map advertising data, GATT UUIDs, a 16-byte frame header, checksums, challenge authentication and car control commands. The client uses those messages to pair with and operate the box.
