Problem adding Thingy:91 in the nRF Cloud

[T1mS_]

Hello,

I try to add a Thingy:91 to the nRF Cloud after I received it today. The sim card got's activated without a problem. When I try to key in my IMEI and the Pin which is printed on the label I receive this error: "There was an error adding your device. It wasn't found. Is it connected?"

How to solve this and add the device to my account?

Hi! 

Can you confirm that the Thingy:91 is on and the LED is blue and blinking.

Best regards,

Heidi

Hi Heidi, 

I think it is more like a blue-withe breathing in a two seconds on and around 5 seconds off interval. 

[Heidi-Irene Harvey Sollie]

Sometimes you have to try many times before it is successful. I suggest using LTE Link Monitor, if you're not already. The Thingy:91 doesn't have soft reset so if it's not working, try turning it off and on and then CTRL + R in the LTE Link Monitor. And be absolutely sure it is running the at_client example.

Also try AT+CGMR to see what version of the modem firmware it's running.

Now it stopped working almost completely. The LEDs are not blinking anymore and in the LTE Link monitor nothing happens. I still can flash it with the jlink device and it also gets recognized in the seriel monitor and also sometimes get some output in the serial monitor.

Now I reflashed the modem and also your thingy91_at_client.hex file.

Still the same result.

I'm now a bit disappointed by the device....

[Heidi-Irene Harvey Sollie]

I'm sorry to hear that. The LED is not supposed to flash with the at_client example.

When you connect it to the COM port in the LTE Link Monitor do you get the log message "Modem port is opened"?

There are two COM ports when the Thingy:91 is connected. Are you sure you are connected to the correct one? Have you tried both?

[T1mS_]

Ok, got it with the LED.

I can not switch between the COM ports. I only can select the device. (See picture)

To get serial output the COM17 is the correct one.

Beside what is shown in the picture, nothing happens, no matter how often I repeat it...

[Heidi-Irene Harvey Sollie]

Try unchecking this selection in the bottom right corner.

[T1mS_]

ok.

All commands still time out.

But doesn't it makes sense, because the modem is not turned on so I can not get a response on my requests? (top right corner - can't make it to turn on...)

[Heidi-Irene Harvey Sollie]

I got the 'timed out' error a few times too and restarting my computer fixed the issue. 

In addition, the modem has to be off to set the system mode, so run AT+CFUN=4 first. Sorry, I should have clarified that earlier.

[T1mS_]

Still the same after rebooting my pc.

IS there a way to reset the modem completely?

[T1mS_]

I also tried a SODAQ (https://shop.sodaq.com/sodaq-sara-sff-r412m.html) board today with LTE-M and NB-IoT capabilities. I was able to connect to the telekom network from exact the same spot like I'm trying to connect the thingy:91...

[Heidi-Irene Harvey Sollie]

There a few ways to reset the modem. However, the best way is just power cycling the Thingy:91, switching it off and on while trying to connect.
