Reverse Engineering a Bluetooth Lightbulb
summary
Reverse engineers a Bluetooth LE bulb protocol, captures packets with an Android BT HCI snoop and an Ubertooth sniffer, inspects pcapng in Wireshark, and writes GATT values via command line gatttool to change RGB bytes. Uses an Intel Edison running a Node server with the noble npm package to map TeamCity webhook JSON to bulb handles, runs multiple bulbs, handles differing handle offsets, and demonstrates reliable build status lights (green/red/yellow) in a working prototype.
