I have a RG255C-GL. Firmware version RG255CGLABR01A08M4G.
I have a Linux system and using QLog_Linux_Android_V1.5.28_2,
self compiled from sources.
When I start QLog, it displays:

Looking into a file, it seems it has no random content in it:

Do I need some AT commands to collect useful info?
I tried e.g. at+cfun=0 and at+cfun=1, but file size seems to remain the same.
Or could it be, QLog has a problem, or does my version not yet work with RG255C-GL?
I can query info via QMI and execute AT commands, so all in all it does not look bad.
QLog_Linux_Android_V1.5.28_2 had some compile problems, perhaps due to local build system. Is there perhaps already a newer version?
Just tried the same QLog against a RM520N-GL (same board, same binary, just connected a different module and there it seems to work:
