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.

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

In the middle of these circles is my position. I have two other LTE-M devices (development boards). At the moment they are not running. This shows what I get from the homepage of Hologram. Vodafone is much better than Telekom at the moment. But Hologram uses all main carriers. That's why I choose them. I do not know about your provider.

I will flash the board to NB-IoT and give an update as soon as possible. Thank you very much for your help so far.

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.
