The bluetooth can also be configured by enabling the correct gpios:
<pre>
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
</pre>
E.g
<pre class="board-terminal">
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
</pre>
Attaching the device:
<pre class="board-terminal">
root@diva:~# hciattach /dev/ttyS1 texas 30000000 flow
