LHG LTE debug 101

Mon Jan 23, 2023 10:29 am

Hi,

I have LHG LTE antenna in remote area and the signal is great and stable with few exceptions.
Almost every night for few hours (from 2AM to 6AM) the LTE connection breaks and I would like to try to understand why.

Here is the log output in the moment when it connects:
Jan/23/2023 06:30:56 lte,async,raw lte1: sent AT%MEAS="7"

With my non-existing knowledge I think that here:
Jan/23/2023 06:30:56 lte,async,raw lte1: sent AT%PCONI
Jan/23/2023 06:30:56 lte,async,raw lte1: rcvd +CME ERROR: Not camped on cell
Mikrotik sends some PCONI query which results in saying that the SIM is not registered to the network.

Then at some point:
Jan/23/2023 06:30:58 lte,async,raw lte1: +CEREG: 3
Jan/23/2023 06:30:59 lte,async,raw lte1: sent AT%MEAS="7"
SIM gets registered and Mikrotik successfully receives reply to his MEAS query.

Can someone please explain to me if I am thinking correctly and possibly give me some more info?
I would like to contact my service provider to ask them to check on their side what is happening in this moments.

Thanks,
Kruno
