TS-7120 Bluetooth

From Technologic Systems Manuals

The WIFI on the board also includes a bluetooth 4.0 LE module. To use bluetooth, it is necessary to first configure the WIFI interface (see Debian WiFi Client). Then, run the following commands:

# Install bluez if it is not already present
apt-get update
apt-get install bluez bluez-tools

# Ensure that the wifi is configured
ifconfig wlan0 up 

# Enable Bluetooth, and load the driver firmware
echo BT_POWER_UP > /dev/wilc_bt
echo BT_DOWNLOAD_FW > /dev/wilc_bt
echo BT_FW_CHIP_WAKEUP > /dev/wilc_bt

hciattach /dev/ttyS6 any 115200 noflow
hciconfig hci0 up
hcitool cmd 0x3F 0x0053 00 10 0E 00 01
stty -F /dev/ttyS6 921600 crtscts

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:
