Bluetooth and FM radio
Bluetooth
Bluetooth provides a fully digital link for communication between a master unit (the phone) and one or more
slave units (e.g. a wireless headset). Data and control interface for a low power RF module is provided by the
module.
The Bluetooth is physically integrated with the FM radio into one single module. From a functional point of
view they, however, have nothing in common.
