Thingy 91X will not connect to nrf.cloud out-of-the-box

[dschipf]

I just received a Thingy 91X, and am having problems out-of-the-box.
I used the "Quick Start" module of the SDK. I selected the option that programs the hello.nrf.cloud connectivity app. After finishing with the "Quick Start" without any problems, I cannot connect to hellow.nrf.cloud. I've tried entering in the fingerprint, and I've tried scanning the QR code. I always receive the same error, which is given below. Does nrf cloud just not recognize my particular device? If this is the case, can you please add my device to the list of devices recognized by nrf.cloud?
Thank you for your help.

I receive the following error:

Connection failed.

The fingerprint you have provided is not recognized, and we were unable to identify the device it belongs to.

Hello, did you test the Thingy:91X out of the box, before programming it with the Quick Start app? The Thingy:91X comes pre-programmed with the Hello nRF Cloud application.

Could you please provide some screenshot of the issue? In nRF Connect for Desktop, open the Serial Terminal and connect to your Thingy:91X. What output do you get from the device? Please copy and paste full application log here. 

Kind regards,
Øyvind

Thank you for your help.

I did not try it before using the quick start. I programmed the Thingy 91X with the hello.nrf.cloud program (through the quick start wizard). I'm using nrfConnect 5.2.0. 

The Thingy 91X has a slow yellow blink when turned on, which according to the documentation means that it is trying to reconnect to the cellular network. Please see the image below for the message I get in the terminal. I am using a linux OS, and the Onomondo SIM card that came with the Thingy 91x, which I registered. I previously owned a Thingy 91X that worked after going through the quick start program and inserting the Onomondo SIM card, so I am a bit concerned that this device is not working. I am in Spokane, WA USA.

Thanks for sharing. Is this all the logs that you get out from the device?

The device is rejected by the network with EMM Cause #17 – Network failure

      This EMM cause is sent to the UE if the MME cannot service an UE generated request because of PLMN failures.

Looking at Onomondo's coverage map the device should be able to connect to AT&T and T-Mobile

Are you able to test with another SIM? This does not seem like an issue with the Thingy:91X directly.

Kind regards,
Øyvind

Hi Øyvind,

I tested this device with both of the SIM cards that the 91X comes with. I've also tested it with two other SIM cards. It doesn't seem to work. I guess I will organize a refund with Mouser.

Regards,

David

As far as I can tell there is nothing wrong with your device, but we will need more logs in order to pinpoint what exactly is failing. 

Could you please provide modem traces from your device with the failing SIM cards? 

Kind regards,
Øyvind
