Hi,
We're using a Cinterion ELS61-E R2 and seem to suffer from a lot of
"packet data disconnects" and cell/rat/MO switching.
We're advised to force the modem to use 3G/2G (or 4G/2G) Radio Access
Technology with the AT^SXRAT command.
We've been told the "AT+COPS=0" may reset SXRAT settings.
I've tried to do this via:
mmcli -m 0 --set-allowed-modes='2g|4g' --set-preferred-mode='4g'
but it doesn't work and even if it would, I'm not sure this means the
"AT^SXRAT" command alwaysf ollows "AT+COPS=0" nicely.
I see no "AT^SXRAT" in the source code, so I guess "AT^SXRAT" is a
Cinterion specific command that isn't supported yet.
I do like to use the "AT^SXRAT" command.
So I'd like to do a "AT^SXRAT" after each "AT+COPS=0". This involves
changing modem_3gpp_register_in_network, is this the right thing to do?
If not, how to best use the "AT^SXRAT" command?
Thanks!
Regards,
Norbert van Bolhuis
