I have a linux filesystem (Debian based) for an embedded board which
uses a Quectel UC20 3G modem via NetworkManager/ModemManager.
I want to upgrade to use a Quectel EC21 4G modem and want to know if I
can use the same "system-connections" configuration file for both
modems. e.g. so that same software can run on new and old hardware - or
do I have to have separate config/connection files for each modem?
My 3G configuration looks like this:
id=telstra-mobile-broadband-1
uuid=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
type=gsm
permissions=user:root:;
autoconnect=true
[gsm]
number=*99#
password-flags=1
apn-telstra.extranet
[ipv4]
method=auto
[serial]
baud=115200
Should this same config file work with a 4G modem (EC21) ?
Can I have the one configuation file that will work on 4G and 3G (e.g.
if only 3G is available). I'm *assuming* yes. If so, how to configure it.
And 3G fallback also. Is there anything special I need to do in
configuration, or will ModemManager just wield its magic.
Thanks,
Brendan.
