export gpio137 gpio138 gpio139 gpio170 gpio64 gpiochip0 gpiochip128 gpiochip160 gpiochip192 gpiochip32 gpiochip64 gpiochip96 unexport

root@localhost:/sys/class/gpio#

</pre>

Export Gpio137 if you don't have it:

<pre>echo 137 &gt; /sys/class/gpio/export </pre>

Set GPIO 137 to low value to reset bluethoot:

<pre>echo 0 > /sys/class/gpio/gpio137/value</pre>
