Hi Pascal,

Unfortunately I could not find time to check after your suggestion, I will check LTE-M option to connect database and share the results.

Many thanks for your help.

Hello Muhammet,

The failure that getaddinfo() doesn't work could be caused because by some (older) operator network setup doesn't support ePCO. You could select the ePCO to legacy mode using AT%XEPCO=0 to select legacy PCO instead of the default ePCO.

You could start to test it also with selecting LTE-M instead of NBIoT if it works with LTE-M and not with NBIoT it is most likely caused by ePCO.

Hello Pascal,

Thank you so much. I checked and confirmed that I do have data on my SIM cards. I'm also able to send and receive data from the Nordic Academy's echo server. Do you have any other suggestions for what might be causing the connectivity issue with the cloud?

As I mentioned earlier, based on the error messages, the issue seems to be related to the getaddrinfo() function. When I try to retrieve the IP address of the cloud or the echo server using getaddrinfo(), I encounter the same error. However, when I manually assign the IP address and create a socket using that IP to connect to the Academy's echo server, everything works fine—I can send and receive data without any issues.

Is there any additional configuration I need to enable in order to use getaddrinfo() successfully?

Many thanks for your time.

Kind regards.

Hello Muhammet,

Then the issue most likely is that you ran out of data on your Onomondo SIM cards.

Check with the status with the provider and if you need to add more MBs to your plan.

Hello Pascal,

I have two Onomondo SIM cards, and I was trying to connect to the cloud using them. As I shared recently, I wasn’t able to connect to the cloud or receive provisioning commands with these Onomondo SIMs. However, when I tried using the Conexa SIM that came with the nRF9151 DK, I was able to receive provisioning commands, and the DK could send data to the cloud without any issues. But when I used this SIM with my application, I encountered the same error I previously shared.

Hopefully this information could be helpful.

Many thanks.

Hello Muhammet,

Ok, could you share the log when it boots? It should display information about the modem credentials. It looks something like this:

Hello Pascal,

Many thanks for your reply.

I am not able to see configuration details of rule that I defined while claiming the device but my latest configuration was like below:

Hello Muhammet,

Your connection is being refused by the server. This is normally cause to wrong credentials on the modem.

Could you expand in detail on how did you provisioned your device? I'm interested to know the configuration you set into the rules to provision when you claim the device (in case you did it directly through nRF Cloud UI).

Regards,

Pascal.
