Which Radio/Moden to choose

[2W0NRE]

I'm seeing red on Modes enabled and Network Status and incomplete Radio Info, so I'm doing something wrong.

sudo pistar-findmodem gives MMDVM_HS_Hat-v1.4.6 20180720 14.7456MHz ADF7021

I've selected MMDVM_HSHat (DB9MAT & DF2ET) for Pi (GPIO) but is that right?

Suggestion: skip the basic "dashboard" page and use the Admin page. It shows a lot more status indicators at the top. Those might reveal something.

I've just disabled D-Star mode on my system to determine what items are needed...

Comparing to your image, the main thing I see is that MMDVMHost is not green. You'll have to check the log files to see what may be causing it to fail. (I had to disable modes on mine as D-Star activates ircDDBGateway along with MMDVMHost). At the simplest, the RF board you have is NOT compatible with the modem selection you made. You'll have to examine the board carefully for any identification markings. Excluding specific manufacturers there are SEVEN MMDVM GPIO boards in the list -- and then one gets named manufacturers...

I can't really tell you what to look for /on/ the board -- I'm running an older DV-MEGA board. If the identification was correct, you are running fairly old firmware (2018), though that's probably the age of my DV-MEGA (I've never updated its firmware; it seems to be working fine, so why go through the hassle of jumpers to enable the update).

Check for date of log file, and it may help to reboot first so the logs are "clean"

How long did you wait after a reboot? The logs are kept in a small RAM drive, so do not survive reboots. I'd have expected to see at least the start of the log files.

Code: Select all

pi-star@pi-star-3b(ro):~$ ls /var/log/pi-star
Headers.log                   ircDDBGateway-2022-08-08.log  MMDVM-2022-08-07.log  STARnet.log
ircDDBGateway-2022-08-07.log  Links.log                     MMDVM-2022-08-08.log

ircDDBGateway is D-STAR, wouldn't expect it for a DMR-only config.

Does /var/log/syslog show anything Pi-Star related? (I show a lot of futile activity from the watchdog -- stopping and restarting various services). Somewhere in all those logs there should be information regarding MMDVM(host) showing why it isn't starting. If nothing even attempts to start it you may need to burn a new SD card with a fresh Pi-Star install, force all upgrades (pistar-update and pistar-upgrade), and THEN reconfigure for your call sign, DMR ID, etc.

Still nothing in /var/log/pi-star after 12 hours

I'll repeat myself -- you may be better off downloading the most recent Pi-Star image, burning a new SD card, running pistar-update and pistar-upgrade until there are no more changes found, THEN reconfigure the hotspot settings.

It'll probably be quicker in the long run.
