an error with quectel data modem #62

Open fjremnav opened 2 years ago

fjremnav commented 2 years ago

I ran the following command with quectel LTE modem:

sudo python3 ./qcsuper.py --usb-modem /dev/ttyUSB0 --pcap-dump test1.pcap --include-ip-traffic

Got the following error:

Error: unmatched response received: DIAG_EVENT_REPORT_F with payload b'\x10\x00\xd8i\x0bF\xfa\x9a\xecq\xf5\x00\x05\xa2\x00\x80\x00\x00', while the request was DIAG_LOG_CONFIG_F with payload b'\x00\x00\x00\x00\x00\x00\x00'. This is possibly due to another client talking to the Diag device (which is forbidden).

Other capture application, like scat works fine. I check my system and can't find any other program to use this dm port

Any idea why this happens.

Thanks,

This happens when the device outputs DIAG data all by itself. E.g. Sierra devices have a CUSTOM setting which enables this behavior, and on several handsets this can be triggered by pressing the right key sequence (see scats README).

I also meet this error on ubuntu and windows!
