That is strange. Not much we can do without more information.

How are you adding the certs?

Here is what I tested with success.

RE: Possible bug in modem firmware for nrf91XX series in newest version (2.0.2)

JonathanRJ — Tue, 17 Dec 2024 11:55:35 GMT

Sorry for the late anwser, i can't provide logs or a trace at the moment since we've had to move along using the 2.0.1 version for now, to meet a deadline. However, when i was trying to make 2.0.2 work, i made sure that the modem was off, using AT+CFUN=4, yet it gave the same error.

Hello!

I'm not familiar with any issues regarding writing certificates (AT%CMNG). Was the modem by any chance activated i.e. AT+CFUN=1? Will investigate more on the issue.

Are you able to provide a modem trace while trying to write your certificates? Could you also provide the logs showing the issue?

Kind regards,
Øyvind
