Hi,
I have an embedded system (buildroot-based) and I'm using NM 1.20.4
and MM 1.16.4. I have two NM connections configured and I want them
active at startup. One is an ethernet with DHCP and the other is a gsm
connection.
Both connections get activated correctly when the system comes up but
the gsm connection gets deactivated after less than a minute or so
with reason 'new-activation'.
I'm trying to figure out why the gsm disconnects. Note that I've tried
with two different modems (Quectel and Simcom) and the behaviour is
exactly the same.
Any suggestions?
Thanks in advance
Juan
