Thingy:91

[MInv]

Hello!

I am trying to connect my Thingy91 to nrfCloud, but after successfully activating the SIM card, I receive error 40412: No device found for this id. The device has not yet been provisioned.

My device was to begin with registered and could be found under “Devices” in nrfCloud. When updating it with the newest release FW, it just would not connect to the cloud, and it only said, “Please connect your device”, even though the device was on. I then deleted the device from nrfCloud, and tried to add it again, and received error 40412.

When updating the FW I followed the steps in the Getting started with Thingy:91 guide and used the newest release from Nordic Thingy:91 Downloads. After receiving the error, I did so again, in order to verify that I did it correctly the first time, but I still received the error. I repeated this process a lot of times, and still got the same result.

I noted that every time I performed the process of the guide, my device never blinked the way the guide said it should. When trying to connect LTE device to the cloud (step 5-8 in “Connecting to nRF Cloud”) , my device goes directly into blinking green three times, which according to the User Interface page indicates trying to connect to cloud. The guide says that it should blink double white for this step of the setup process, cloud association.

I also had a look at the LTE Link Monitor and noticed that the signaling connection status notification (+CSCON) switches between idle and connected mode. Could this be related to the error code? 

The SIM card was successfully added, when I tried to add the device, and is listed under “SIM card” in nrfCloud. I am also located in Norway, which according to IBASIS should have national LTE-M coverage.  The thingy:91 I am using is version 1.6.0. 

Am I doing something wrong here, that I am just not able to see myself? Or do you have any other suggestion as to why the device won’t connect to nrfCloud?

Thank you in advance!

Best Regards

Martha

When you update the firmware in the nRF52840 SoC, what does the device look like in the "Select device" menu? Would you be able to take a screenshot?

I also had a look at the LTE Link Monitor and noticed that the signaling connection status notification (+CSCON) switches between idle and connected mode. Could this be related to the error code? 

Could you please share the log from LTE Link Monitor? (Click "Open log file" at the bottom.)

When pressing SW4 while switching SW1 to ON, for programming of nRF52, the device looks like this, under "Select device": 

 

Here is the log:

Let me know if you need more of the log.

Hi Martha, sorry for the delay.

The last log shows that the device does get a valid IPv4 address from the network so it could be an LTE connection has an issue. Could it be that you are out of data? Could you please check the data plan? 

You could also do a pin(Edit: ping) test with the serial_lte_modem sample to confirm and run a test like this:

AT+CFUN=4
AT+CFUN?
AT%XSYSTEMMODE=1,0,0,0
AT+CEREG=5
AT+CFUN=1
AT+CFUN?
AT#XPING="www.google.com",45,5000,5,1000

XPING is only supported by serial_lte_modem sample and does not work with at_client.

Hi, 

When checking the nrfCloud sim card section, the sim card should have a good amount of data left. 

[helsing]

Thank you for ruling this out. Did you have any luck with the ping test?

[MInv]

Hi, I have not yet tried the ping test, I will update you when I have. Sorry for the late response!

[helsing]

Hi,

The results from the ping test will be interesting.

Have you tried connecting using another SIM-card?

my device goes directly into blinking green three times

Is the device blinking green continuously, or does it have a longer break in between the three green flashes?

Which of the files did you program into the SiP?

• thingy91_asset_tracker_v2_2022-09-15_7a358cb7.hex

or

• thingy91_asset_tracker_v2_nbiot_legacy_pco_2022-09-15_7a358cb7.hex

[MInv]

Hi, 

Trying another sim card worked, so there must be an issue with the sim card I tried at first. 

For information the blinking did not have longer breaks, and I programmed it with the first of the two hex files you suggested. 

My Thingy:91 now sends data to the cloud, so thank you for your time and help! 

[helsing]

Great to hear that you are connected, and thank you for your patience!

Have you tried removing the SIM card from nRFCloud, and then adding it again later? (I do not know whether this has worked with other SIM cards.)

If you want to, we could dig into why the SIM card did not work. What type of SIM card did you replace the old one with?

[MInv]

Hi, 

Yes I have tried to remove it, then add it back again. Both SIM cards are iBasis eSIM cards. I think we can regard this ticket as solved. 

Again, thank you for your time and help regarding this ticket!
