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?

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.

Hi Marcus,

It has come to my attention that the Map you shared with regards to coverage is for LTE, not for LTE-M (CAT M1) or NB-IoT (CAT-NB1).
So there has been a misunderstanding between the technologies here.

nRF9160 is using the low power/low bandwidth technology for LTE, as shown in the Figure.

So the coverage map is not valid for CAT-M1 or CAT-NB1.

None of the network providers shown in the coverage map supports LTE-M, except Telefonica and they tend to have limited coverage (at this moment) and you can only connect to their network using their SIM card. You can purchase it from their IoT Division.

I talked to someone who is using the nRF9160 in Germany, which has had good experience using the "1nce SIM"  (Deutsche Telekom) running on the NB-IoT network.

(If you want you can get in contact with the RSM in Germany if you need some additional information about this, just send me a personal message on Devzone)

 

Best regards,
Martin L.

Hi Martin,

you are right. The map was not the correct one. I've also done some research too and found out that Vodafone ist the preferred carrier for Germany. Some friends have very good experience with them. NB-IoT and LTE-M should work here as Hologram or your service sets up on one of these carriers. There is no detailed information about the coverage available. But the sender will most likely be placed at one of the LTE stations. NB-IoT has a better reach than LTE-M so it should connect to something. I can see some data coming in. But it is not enough to establish a connection. 

Best regards 

Marcus
