Is this only happening to particular network operator?
Will there be any crash if no data channel establishment?
Will there be any crash if using mbim instead rmnet interface in at!usbcomp?
Do you see crash in linux pc?
Is this only happening to particular network operator?
we tested with three operators and all gave the some results
Will there be any crash if no data channel establishment?
I will check that
Will there be any crash if using mbim instead rmnet interface in at!usbcomp?
Do you see crash in linux pc?
No we didn’t test it in linux pc and we use qmi and never tried mbim
hello
I switched to mbim mode and there are a lot of firmware crashes

OK
but mbimcli respond without any issue (without stress test)
is it possible to connect to linux machine or windows machine?

No and We need it to work with openwrt platform,
Now I work with mbim mode and the module never crashes until now, but
1- there are always firmware crashes (see below)
2- I saw that I can run qmi command while the module is in mbim mode is this normal behavior

OK
yes, qmi message can run over mbim interface
I understand you need to work with openwrt, but if you can run in linux or windows, at least we can isolate if problem only exists in operwrt
