4.2.2.6 Bluetooth

We use Qualcomm BTS4025 as main Bluetooth transceiver IC which
supporting voice and data communication function. Its working    mode
or state is controlled by QSC6085 via UART inferface. The PCM voice
siganal interfacing with BTS4025 is processed by QSC6085 directly.The
MT6223D analogy signal was transferred via the CODEC of QSC6085 .

And BTS4025 needs a external 32MHz crystal as clock source and use
the QSC6085’S LDO as power source.
