[Ovmsdev] SIM7600 Registration Denied

Thu Sep 8 13:15:44 HKT 2022

Michael,

I reviewed:

$ git diff 2b25287fbef5fa968236cb8e556ea11da7c8f579 components/ovms_cellular components/simcom

But can’t see anything really related to frame errors, other than the two extra CGREG and CEREG output lines once every thirty seconds.

Maybe an existing issue re-occurring?

Do you think this should block our release of 3.3.003 to ‘main’ release?

Regards, Mark.
