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 has a separate built in antenna and is powered by VBAT and the regulated voltage VIO. For

audio applications the Bluetooth has a PCM data bus. In addition a UART (universal asynchronous receiver/

transmitter) is used for data communication and controls.
