Bob her with my 2 cents,

It's not clear to me what you want to accomplish. If the second node is a transmit only of the first nodes activity, then why not link the two nodes so the second merely repeats the activity on the first. I may be missing something, but using the gpio seems overly complicated. The second node could even be a private node, or do you require linking from outside your server?

Thanks,

Bob

Hello all,

I want to set up an app_rpt server with two independently functioning simpleusb nodes:

Node 1. Full duplex repeater

Node 2. Aux transmitter

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" ?
Thanks and 73
