No SIM Slot Paths

[Bushman, Jeff]

I switched my modem back to QMI mode via the at!usbcomp=1,1,10D command.

Now I see the slot information in mmcli.

  ----------------------------------
  SIM      |       primary sim path: /org/freedesktop/ModemManager1/SIM/0
           |         sim slot paths: slot 1: /org/freedesktop/ModemManager1/SIM/0 (active)
           |                         slot 2: none

I guess this modem firmware just doesn't implement the full range of MBIM commands. Thanks for your help.

Jeff

This is what I get:

So it appears that the data is there in QMI mode, but not MBIM mode?

Hey,

Let's confirm whether the modem supports them or not; Jeff can you run the following commands in the MC7455?

$ qmicli -d /dev/cdc-wdm0 -p --uim-get-slot-status $ qmicli -d /dev/cdc-wdm0 -p --uim-get-card-status $ mbimcli -d /dev/cdc-wdm0 -p --ms-query-device-slot-mappings
