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.
Bluetooth connects to TikuEDGE on the GENIO and GPIO busses.
The Bluetooth module is provided with power from an external LDO (Low drop out) regulator.
FM radio and Bluetooth are physically placed in the same module, but they function separately and
independently from each other. Information about the
module section.
