AI explanation

Within a Bluetooth piconet, the master assigns each active slave a temporary 3-bit Active Member Address (AM_ADDR) that identifies it for communication, and every packet exchanged carries that address. A PIN is only used during the pairing/authentication stage, and the clock (CLK) governs frequency hopping, not identification. Therefore a device is identified for communication by its position (AM_ADDR) in the piconet.
