The Wi-Fi option for this platform also includes a Bluetooth 2.1+EDR and Bluetooth 4.0 LE radio. 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.
To connect this to the system first pulse the BT_EN pin, and then call hciattach:
echo 237 > /sys/class/gpio/export
echo low > /sys/class/gpio/gpio237/direction
echo high > /sys/class/gpio/gpio237/direction
sleep .1
hciattach /dev/ttyAPP0 texas 115200
hciconfig hci0 up
Once this is loaded you can scan for devices with:
hcitool scan
This will return a list of devices such as:
14:74:11:XX:XX:XX BlackBerry 8530
Please note that the Bluetooth module requires the modem control lines CTS and RTS as flow control.
