TS-7680 Bluetooth

From Technologic Systems Manuals

The WIFI option on the board also includes a bluetooth 4.0 LE module. To connect this to bluez 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:A1:1E:C9	BlackBerry 8530

Bluez has support for many different profiles for HID, A2DP, and many more. Refer to the Bluez documentation for more information.

Please note that the Bluetooth module requires the modem control lines CTS and RTS as flow control.
