Introduction[edit | edit source]

SBC Diva can be populated with DWM WiFi/Bluetooth combo plugin to easily add wireless connectivity. In order to enable the bluetooth, the correct device tree configuration must be passed to the kernel. The sbcd comes with two possible devicetree configurations. The default one enables the UART1 and therefore the bluetooth and wifi module while the other enables the CAN interface and disables the UART1.

Note: In order to enable the DWM module, the correct device tree file must be loaded.

Wifi[edit | edit source]

To enable the wifi, the gpio114 pin must be configured. Once this has been done, the wlan0 interface should become accessible.

The gpio pin can be enabled as follow:

echo 114 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio114/direction
echo 1 > /sys/class/gpio/gpio114/value

E.g

root@diva:~# echo 114 > /sys/class/gpio/export
root@diva:~# echo out > /sys/class/gpio/gpio114/direction
root@diva:~# echo 1 > /sys/class/gpio/gpio114/value

Bluetooth[edit | edit source]

The bluetooth can also be configured by enabling the correct gpios:

echo 114 > /sys/class/gpio/export
echo 115 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio114/direction
echo out > /sys/class/gpio/gpio115/direction
echo 1 > /sys/class/gpio/gpio114/value
echo 1 > /sys/class/gpio/gpio115/value

E.g

root@diva:~# echo 115 > /sys/class/gpio/export
root@diva:~# echo out > /sys/class/gpio/gpio115/direction
root@diva:~# echo 1 > /sys/class/gpio/gpio115/value
root@diva:~# rfkill list
0: phy0: wlan
        Soft blocked: no
        Hard blocked: no

Attaching the device:

root@diva:~# hciattach  /dev/ttyS1 texas 30000000 flow
Found a Texas Instruments' chip!
Firmware file : /lib/firmware/ti-connectivity/TIInit_7.6.15.bts
Loaded BTS script version 1
texas: changing baud rate to 3000000, flow control to 1
Device setup complete

Once the device has been attached using hciattach the hci0 interface should become visible:

root@diva:~# rfkill list
0: phy0: wlan
        Soft blocked: no
        Hard blocked: no
1: hci0: bluetooth
        Soft blocked: no
        Hard blocked: no

Bluetooth scan example:

root@diva:~# hciconfig hci0 up
root@diva:~# hcitool scan
Scanning ...

        C8:94:BB:A0:7C:1F       wifi mp

The devices have been successfully recognized.
