Hello Ken-
Sorry this is kind of long but should be all necessary details. I'm new to all this but I'm computer/Pi/Linux savvy so I've been digging in.
I'm glad to know I'm not the only one with the issue on the Pi Zero.
This is what is currently working for me, letting me be on both networks at the same time for over a week now.
MMDVMHost Configuration:
DMR Mode: on
MMDVM Display Type: OLED type 3 on /dev/ttyAMA0
General Configuration:
All my location settings and STM32-DVM hat, as normal
DMR Configuration:
DMR Master: DRMGateway
All other settings are default (not currently using Brandmeister)
Attached are a screenshot of my Admin screen (note the displayed active BM connection despite it being disabled in the configuration) and my DMRGateway file with my personal information replaced with "your-xxxxx" for you to fill in.
This setup works for me just fine on the Pi Zero. The Legacy talkgroups start with 5 and the Prime with 4.
From the radio (you need to pad zeroes to make 7 digits):
Dial 5000777 for Legacy scan
Dial 5031665 for Legacy "TGIF" talkgroup
Dial 50xxxxx for your Legacy talkgroup of choice, padding zeroes as necessary
Dial 5004000 for Legacy disconnect
Dial 4000777 for Prime scan
Dial 4031665 for Prime "TGIF" talkgroup
Dial 40xxxxx for your Prime talkgroup of choice, padding zeroes as necessary
Dial 4004000 for Prime disconnect
From the dashboard Admin tab:
Enter your talkgroup of choice (just the TG number), click Link, and then Modify static to change TGs on Legacy
You can do this while the hotspot is transmitting, for example to break out of a busy QSO or scan.
From your web browser:
https://prime.tgif.network/profile.php?tab=SelfCareEnter your Prime talkgroup of choice here. No padding here, just the straight TG number. Works while the hotspot is transmitting
http://tgif.network:5040/api/sessions/update/your-dmr-id/1/4000This will send a 4000 disconnect on Legacy.
You can keep a browser tab open, change the TG number and hit enter to move around. Redundant since the dashboard works but interesting.
This combination is letting me move around freely on both networks - with the radio if the hotspot isn't transmitting and with the dashboard/self care if it is or if it's more convenient.
If I switch off DMRGateway and put everything back to just Legacy settings, it still doesn't work at all. I have no idea why but I'm not touching anything until the switchover to Prime.
Hope that's helpful to you, Ken, or anyone else who might find it useful.
