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.

Hi 

Did it allow to change SIM card at DK board after registering the device at nRF Cloud?

Thanks.

Hi Jeffery!

This should not be a problem. Could it be related to the fact that you deleted your certificates, as you mention in this thread?

Hi Richard

Did you try changing a activated SIM card at DK board? Everything is ok?

I got error as below at UART dump when my DK tried to connect nRF Cloud. nRF Cloud refused it.

nrf_cloud_connect failed: -111

Hi again!

I tried just now and it worked fine. Are both cards registered on nRF Cloud? Have you altered the on board certificates?

Best regards,

Hi Richard

Describe my operations in more detail.

1. Person A activated the iBASIS SIM at his nrf cloud account. => OK. Can connect.

2. Person A deleted the iBASIS SIM at his nrf cloud account. => OK.

3. Person B activated the iBASIS SIM of person A at his nrf cloud account. => OK. Can connect.

4. Person B deleted the iBASIS SIM at his nrf cloud account. => OK.

5. Person B activated the iBASIS SIM again at his nrf cloud account.

            => Failed. nrf_cloud_connect failed: -111. nrf could apps refused the connection. I cannot find a

                  way to solve this problem.
