 ## Bluetooth Pairing and Profiles
 
 ZMK support bluetooth “profiles” which allows connection to multiple devices (5 by default). Each profile stores the bluetooth MAC address of a peer, which can be empty if a profile has not been paired with a device yet. Upon switching to a profile, ZMK does the following:
