Modem working but having Timeout Exception

[fmaltez]

am able to run the script, and it makes calls and even sends SMS with my E173 modem but I always get exceptions in the code.

What might be the issue?

I'm running this in Python 3.8.10 in Ubuntu 20.04.4 LTS

python3 identify-modem.py /dev/ttyUSB0
args: Namespace(baud=115200, debug=False, pin=None, port='/dev/ttyUSB0', wait=0)

For this specific modem you have, you need to use the notification channel under ttyUSB2, otherwise it won't work

Can close the ticket

[ebowwa]

may you elaborate? What about with a waveshare sim7600x modem? @tperalta82

I don't have one of those, so I cannot test nor debug my friend!
