I've been struggling to install my PCI-E MC7455 modem.
After a lot of poking around, it seems like the is a problem with the implementation of UQMI and /or qmi.sh
When I run:
#uqmi -s -d /dev/sdc-wdm0 --get-pin-status
"Invalid QMI command"
In the qmi.sh, this leads to a PIN_STATUS_FAILED error
I'm running the latest firmware (SWI9X30C_02.30.03.00 VERSION 002.046_001), and have disabled the PIN on the SIM card. OpenWrt is 18.06.2 running on D-link DWR-921 C3
For now, I've hacked qmi.sh, modified line 86 to grep on "Invalid QMI command" instead of "Not supported".
How can this be changed so it can work for others in upcoming releases?
