System mode from ntn to lte doesnt save to non volatile memory

Hi! This is a general info post since i have found a temporary fix to it, but whilst trying out ntn, we noticed that when switching from %XSYSTEMMODE: 0,0,1,0,0 to %XSYSTEMMODE: 1,1,1,3,0 CFUN=1 hangs and causes the config to not be saved thus remaining stuck in ntn mode, working with monogoto, we figured the only fix was to run a factory reset then to run the system mode command and CFUN=1 which this time doesnt hang.

Hello, have you configured %CELULLARPRFL? If so, you cannot configure multi-mode systemmode. %XFACOTRYRESET wipes CELLULARPRFL, and thus multimode works again. A cleaner way to do this is to delete the configured cellular profile with e.g. %CELLULARPRFL=2,<profile id>.

See chapter 13.2 Cellular profile configuration %CELLULARPRFL in the nRF91x1_ntn_at_commands_reference_manual in the NTN Alpha Documentation Package.

Kind regards,
Øyvind

Monogoto SIMs do not support multiple cellular profiles.
