Use an events stanza and use the "RPT_TXKEYED" to run a function
or command to executes a cop command to turn GPIO on and off.<br>
<br>
This page details how to use events subsystem:<br>

<br>
The cop command for GPIO4 would be something like:<br>
90=cop,62,GPIO4=0 ; Turn off GPIO 4<br>
91=cop,62,GPIO4=1 ; Turn on GPIO 4<br>
<br>
and a "rpt fun 1999 *91" would turn GPIO4 on and *90 turns it off.
<br>
<br>
And use the audio from the left or right channel.<br>
<br>
Or easier yet..you can just share PTT and audio with your primary
node to the second transmitter. <br>

<div dir="ltr">Hello to the group,
<div>
<div>I want to set up a BBB with two simpleusb nodes: </div>
<div>1. Full duplex repeater </div>
<div>2. Aux transmitter</div>
<div><br>
</div>
<div>The second node is nothing more than a transmitter (TX
audio, PTT) so couldn't I simply configure the second node's
simpleusb.conf file with "gpio4 = ptt" , "txmixa=no", and
"txmixb=voice" ? <br>
Thanks and 73<br>
