Support for Bluetooth is provided by the BlueZ project. BlueZ has support for many different profiles for HID, A2DP, and many more. Refer to the BlueZ documentation for more information. Please see our BLE Examples page for information on installing the latest BlueZ release, getting started, and using demo applications.
First load the driver in bluez. For 5.10 and later, run:
btattach -P qca -S 115200 -B /dev/ttymxc1 &
For kernel 4.9 and below, run:
echo 27 > /sys/class/gpio/export
echo low > /sys/class/gpio/gpio27/direction
sleep .5
echo high > /sys/class/gpio/gpio27/direction
hciattach /dev/ttymxc1 qca 115200 -t30 flow
Either will create an hci0 interface that can interface with bluez. For example, to scan devices use blutoothctl commands power on and scan on.
