Connect bluez

Move firmware to where the driver expects

mkdir /lib/firmware/brcm
cp /etc/bluetooth/BCM4345C0.hcd /lib/firmware/brcm

Attach bluez stack to uart

Test microphone recording use the following command

arecord -D sysdefault:CARD=0 --format=S16_LE --duration=5 --rate=16000 --file-type=wav out.wav

...or to record from all 4 microphones:

arecord --device="sysdefault:CARD=AMLAUGESOUND" --channels=4 --format=S16_LE --rate=48000 --vumeter=mono --file-type=wav test.wav

Download recording

adb pull out.wav .
