TS-TPC-7990 Bluetooth

The WIFI option on the board also includes a bluetooth 4.0 LE module. This is supported in Linux using the Bluez stack.

# First bring up wifi.  This loads the firwmare for
# both WIFI and Bluetooth
modprobe wilc3000
ifconfig wlan0 up
# WIFI can optionally be brought back down
# ifconfig wlan0 down

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:
