The WIFI option on the board also includes a bluetooth 4.0 LE module. To use bluetooth, it is necessary to first configure the WIFI interface. Then, run the following commands:
hciattach /dev/ttymxc1 any 115200 noflow
hciconfig hci0 up
hcitool cmd 0x3F 0x0053 00 10 0E 00 01
stty -F /dev/ttymxc1 921600 crtscts
# If your board is REV A use this setup instead:
echo 237 > /sys/class/gpio/export
echo low > /sys/class/gpio/gpio237/direction
echo high > /sys/class/gpio/gpio237/direction
sleep .1
hciattach /dev/ttymxc1 texas 3000000
hciconfig hci0 up
Now you may scan for available devices with:
hcitool scan
This will return a list of devices such as:
14:74:11:AB:12:34 SAMSUNG-SM-G900A
You may request more information from a detected device like so:
hcitool info 14:74:11:AB:12:34
This will produce lots of details about the device, for example:
