Hi Aleksander,
My apologies. It seems my MM got built without QMI_MBIM_QMUX_SUPPORTED flag hence below issues. After re-building MM with this flag, I can see "Channel" and "Modes" sections correctly.
Thanks

Hi Aleksander,
It seems the bands are missing in MBIM mode and QMI is fine. Please see below output with MBIM and QMI as well. You will notice that:
1) "Bands" section is missing in MBIM
2) "Modes" section not showing all "supported" options in MBIM
Both of above are correctly shown in an older MM release (1.12.6)
Thanks
MBIM

Hey,
>
> I'm testing MM 1.18.2 release and finding that the supported bands and current bands are shown empty. I'm using EM7511 modem in MBIM mode in OpenWRT framework (with QMI over MBIM enabled). The bands are displayed correctly in an older MM release (1.12.6). Please let me know what additional information I can provide regarding this.

Could you give here the output of "mmcli -m 0" when running 1.18.2?
