AM_ADDR
Active Member Address
The Bluetooth AM_ADDR (Active Member Address) represents an address used to distinguish between the active members participating in a piconet. Each piconet has one or more slaves connected to a master. The master allocates each active slave a temporary 3bit address. Any packets exchanged between master and an active slave will carry the associated AM_ADDR. The AM_ADDR is used for both master-to-slave packets and slave-to-master packets. The all-zero address (000) is used by the master for broadcasting packets.
