I’m trying to connect an embedded setup (NVIDIA Jetson Nano + Ubuntu 18.04) via a GL7600 to the Internet (using NCM mode). I was following the instructions in this SWIR technical note (paragraph 4).
We can get through all the steps, and as a result we seem to get a connection (ping to a machine on the internet works).
However, a few seconds after routing traffic through the interface (step 8), the modem resets (that is, all serial and ip interfaces/devices are removed from linux and then re-added 5-10 seconds later). Also AT+GST=1 shows that the modem uptime goes back to zero, thereby confirming the reset.
I was not able to to find any reason for this behavior or reports of it.
I tested two different GL7600 and also different host setups - always the same problem.
Is there a Technical Note how to setup the GL7600 that differs from the description I was using (HL7500)?
Thank you for your time and I hope somebody has some more insight.
