Hi Daniele,
I'm patched my MM 1.18.2 with your MR (LN920 Initial Support) and testing LN920
in MBIM mode. I'm noticing that the "supported" and "current" bands are not
shown in "mmcli -m 0" output and below error is seen in the logs:
<warn> [modem0] couldn't load supported bands: Could not find 4G band flags
from response
Any suggestion what could be going wrong?
mmcli -m 0 output in both MBIM and QMI is below:
