Many amateurs want to use the DMR Gateway module in their Pi-Star configuration as it provides much more flexibility in the choice of DMR networks and Talkgroup mapping than the ‘simple’ default configuration.
One issue we noticed on some Pi-Star’s when using the DMR Gateway, FreeDMR would drop out – the Network Status light on the Web dashboard would turn red after a few minutes. Nothing seemed to fix it.
However, this annoying issue was eventually solved by changing the ‘service’ setting in the DMR Gateway service file to ‘Type=simple’. The original discussion where the fix was noted is on forum.pistar.uk
