RepeaterBuilder v4 PTT not working
Posted: Sun Jan 21, 2024 9:29 pm
I have a new v4 Pi-Hat board and trying to get the MMDVMcal working. I have it connected to a VXR9000 repeater in mixed mode. I can hear DMR audio on the TX audio output of the DB9 connector. But the PTT output LED or pin voltage does not toggle.
1. run sudo pistar-mmdvmcal
2. toggled TX/RX with spacebar. No PTT LED. Can hear audio directly on the DB9 output pin.
3. Tried inverting PTT polarity. No PTT LED.
4. Updated firmware from http://dvswitch.org/files/HAM/MMDVM/Ver ... dvm_f4.hex
5. No PTT LED toggling in mmdvmcal.
Using Pi-Star 4.1.7 (also tried WPSD with similar results)
Modem type set to STM32-DVM / MMDVM_HS - Raspberry Pi Hat (GPIO)
This is a new board received a couple weeks ago and have never had it on the air.
Can anyone confirm the Modem type is properly selected?
Did i update with the wrong firmware to cause other issues?
Any thoughts?
