AW: h5321gw Problem with --location-get

[Thomas Lang]

Hmm. I tried at+CREG? To get the CellInfo. But I the response is empty. In the Debug the info is present:

ModemManager[3184]: <debug> [1490255043.880383] [mm-port-serial.c:1237] mm_port_serial_open(): (cdc-wdm2) device open count is 2 (open)

Can I use the mmcli -m 0 --commnad=+CREG?

I updated my HS2350 (rebranded h5321gw) to MBIM-enabled firmware R3C11 and tested it out.

The MBIM protocol does not give ModemManager the LAC/CI at all, so MM can't actually tell you any of that.  And it's a bug in ModemManager that it says MBIM devices actually have 3gpp-lac-ci capability; that should be removed.

In the case of the Ericsson devices though, they still present an AT port, so it's possible we could get that information via the AT port while still controlling the modem with MBIM.  Unfortunately though, that's not implemented.

If you can manage to flash it back to R1D08 or whatever is the pre-MBIM firmware, it'll get used as a normal "MBM" modem and that would allow LAC/CI presentation.
