If change iBASIS sim card to another PCA10090 DK board

[Jeffery]

Hi

There are two PCA10090 DK boards. Each one had its own iBASIS card.

Previously, I registered these two in nRF Connect for Cloud. DK board A with SIM card A.

DK board B with SIM card B. Both of them can connect to cloud and work simulated GPS and orientation.

Then, I tried to swap SIM cards. That is DK board A with card B and DK board B with card A.

I found they can not connect to cloud. Why?

Did nRF Cloud identify the device for modem information and SIM card information both?

Thanks.

Jeffery

Hello,

This might be a case of a bug that has been witnessed a lot lately. It's being worked on to fix it.

I'm also experiencing this on my device after I removed it from nrfcloud and are trying to re-activate it.

I get this message, and then the device reboots and it all repeats.

Do I have to do anything to be able to re-connect my device to nrfcloud?

It could be that you have accidentally deleted or overwritten the certificates. If that's the case this post shows how you can recover them.
