Sorry, I'm not a qmi protocol expert so maybe I'm missing something,
but those seem not to be useful to me for understanding the issue.
Could you please send AT#MONI in one of the available serial ports and
report the output?
Has this modem ever worked properly with a different setup (e.g. SIM, OS...) ?
The only real hint I can provide is to contact Telit technical
support: they will probably ask you to update the firmware and retry
and, if the problem persists, maybe collect a qxdm trace (that will
definitely explain why the modem is not registering).
Regards,
Daniele
