Can't connect Thingy 91X to hello.nrfcloud

[SteppedGears]

Hello,

I'm trying the Thingy 91X but I'm having a few issue with the demo application that connects to hello.nrfcloud.com:

After flashing it with the Quick Start from the nRF Connect for desktop, it apparently connects to the network but then I get this error on the serial terminal:

[00:01:16.525,756] <inf> nrf_cloud_coap_transport: Request authorization with JWT
[00:01:16.901,885] <err> nrf_cloud_coap_transport: Device not authenticated; reconnection required.
[00:01:16.901,916] <inf> nrf_cloud_coap_transport: Authorization result_code: 4.01
[00:01:17.404,602] <err> transport: nrf_cloud_coap_connect, error: -13, retrying

I also get a "Connection failed" error from hello.nrfcloud.com: "The fingerprint you have provided is not recognized, and we were unable to identify the device it belongs to."

From the quick start, I've used the "Start prototyping" entry, with the hello nRF Cloud example.

Initially I tried with the provided SIM cards, but then I've found that they don't provide connectivity in Italy, where I'm based. I'm using a SIM card that works now, and the device apparently is registered to the network.

Should it work out of the box, or there are some extra steps to perform?

Thanks!

Hello,

It should work out of the box.

Initially I tried with the provided SIM cards, but then I've found that they don't provide connectivity in Italy, where I'm based. I'm using a SIM card that works now, and the device apparently is registered to the network.

That's weird, the Conexa/Wireless Logic SIM should have connectivity in Italy according to their website, while Onomondo does not, that is correct.

Though coverage may vary inside the country of course.

Can you tell me which SIM card did you get from which local operator? Sometimes operators sell IoT cards that don't support LTE-M or NB-IoT.

Best regards,

Michal

Hi Michal,

I'm using a SIM from Things Mobile. If I check the network registration status with CEREG, this is what I get:

at AT+CEREG?
+CEREG: 5,5,"5A24","0091560B",7,,,"00100010","11100000"
OK

So it is connected using LTE cat M1.

Yeah, I've noticed that Conexa/Wireless Logic should work here, yet when I try it can't even register to the network. Maybe the SIM is just not active to work here.

Best,

Franco
