Impossible to connect device (Thingy:91) NO WAY TO ENTER HARDWARE (IMEI, PIN).

[timabra]

"There was an error adding your device. It wasn't found. Is it connected?"

IMEI and PIN entered several times.

I do not want to post the ID's here.

By the way: HW-ID? Where do I get the HWID? Or do I have to install the DEV-IDE first?

Hi Marcus,

The HWID is related to the nRF91DK.
When working with the Thingy:91 you should use the IMEI + PIN code.

The Thingy:91 needs to be connected to the network to be able to be paired with your cloud account. 
The default application running on the Thingy tries to connect to the LTE-M network, so if you are in an area where you only have nb-IoT you need to flash the nb-iot version of the application.

When connecting to the nb-iot network you most likely have to use a local SIM from the carrier provider since the iBasis has limited support on the nB-IoT network.

If you do not have an nrf91DK or an external j-link with a 10-pin cable to connect to the Thingy:91 you can switch out the Firmware by following this guide: https://devzone.nordicsemi.com/nordic/cellular-iot-guides/b/getting-started-cellular/posts/thingy91_2d00_fw_2d00_update_2d00_mcuboot

Thank you  very much for the explanation and reply.

- Here in Hamburg there should not be an issue with a connection (LTE-M / NB-IoT)

- In the documentation the blinking blue LED is descirbed as a sign for connection

- In your video it is told that there should be a green light.

- Also in your video it is told that the registration comes first and then the device is connected

So which way around? 

I also tried a different SIM from Hologram. It does also not work properly. No Connection.

Sorry, but there seems to be an issue with the device. 

I would like to return this one and get a new one.

Hi Marcus,

From this list you can see which carrier in your country support the different networks:
https://www.gsma.com/iot/deployment-map/#DE

The iBasis SIM card states that they have "Limited coverage" in Germany.
The issue is most likely not with the device, but with the SIM + and which network you are trying to connect to.

---

The "green light" represents that the device is ready for pairing with an nrf cloud account and the "dark blue" light represents that you have a connection with your nrf cloud account.

(user guide)

• Please state what you are actually seeing from the Thingy:91 when it comes to the LED indicator.
• How do you know that you have coverage in your area with LTE-M and/or nb-IoT?
• Have you verified this in some way?

From what I can see from the official list from GSMA and the Hologram coverage site:  

I would assume that you could get a connection by using the Hologram SIM and running the nb-IoT version of the Thingy:91 FW.
You can download that here.

Then you follow the guidelines presented in the previous post and flash the "thingy91_nbiot_legacy_pco_v0.2.2" version. 
(Legacy PCO means that you are not enabling ePCO in the modem, since from experience the eNB (basestations) in your area supports legacy PCO)

So please flash the NB-IoT version and you should get a connection.

I flashed the device three times. First with the legacy, then the with ePCO and the legacy again. The device  was put outside each time it was flashed to establish a connection. In each attempt the SIM card was also changed between Hologram and your provider.  After these unsuccessful  attempts the device was active the whole night on NB-IoT but did not manage to get a connection. So all in all there is not much left to tryout.
