If you don't have it, you should export gpio137: <br>

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

Set gpio137 to low value to reset disable bluethoot:

<pre>echo 0 &gt; /sys/class/gpio/gpio137/value</pre>

Check that:

signals: mcbsp3_dr | uart2_rts | NA | NA | gpio_141 | hsusb3_tll_data5 | NA | safe_mode

root@localhost:/sys/kernel/debug/omap_mux#

</pre>
