# Chsmartbulb: reconstructing Bluetooth bulb controls

> Chsmartbulb documents Bluetooth control of a combined RGB bulb and speaker sold as BL08A. The author captured traffic from an Android phone and provides a script that replays color-control sequences; the findings identify SPP over Bluetooth EDR as the app's color-control channel.
