I’ve looked at the various threads regarding using GPIO but none really seem to address my situation.
ASL Beta 2.0 running on a Pi3+
Repeater Builder RIM-Lite interface using usbradio.so driver
The RIM-Lite uses the CM119A and it uses GPIO3 as PTT controI and I thought it would be nice to be able to control the PTT line (for external applications) via GPIO manipulation.
So I tested things…
In usbradio.conf, I placed:
gpio3 = out0
and in rpt.conf, I placed:
962 = cop,62,GPIO3=501 (supposed to set GPIO3 to a logic 1 for 500 ms)
Restarted asterisk and from the bash CL:
root@AH6LE-HUB:~# asterisk -rx ‘rpt fun 1100 *962’
Nothing - PTT didn’t go active. So I went to the Asterisk CLI, hoping to see some debug info:
AH6LE-HUB*CLI> rpt fun 1100 *962 AH6LE-HUB*CLI>
Thoughts (other than I’m always pushing the envelope!)
