Good afternoon, I am currently trying to unlock my Quectel RM520N-GL on Linux Debian with the ModemManager (Version 1.20.4).
mmcli -i any --pin=<SIMPIN> >> error: couldn't send PIN code to the SIM: 'Timeout was reached' Runs into a timeout and still manages to unlock the SIM-Card. Afterwards the state changes from "locked" to "registered". For debugging, I did grep the journal: systemd[1]: Starting ModemManager.service - Modem Manager... ModemManager[4418]: <info> ModemManager (version 1.20.4) starting in system bus... systemd[1]: Started ModemManager.service - Modem Manager.
