Net Thingy 91 not connected to LTE in Romania. Do you have a firmware to connect through Vodafone network, which was detected but is not connected. I updated the certificate too. I'm located in Bucharest and here the signal is good.

I need your support to solve this matter urgently because we are developing a IOT solution to monitor several thousand motors - one Thingy 91 for each motor.

I can provide logs for LTE monitor but I saw some previous topics which were not finalized for Romania and Bulgaria. Is this solution working in these countries?

If yes, please provide me the right firmware to update via USB.

Best regards,

Bogdan

I found them, they were hidden between the pictures. I've taken a look at them but I didn't find any glaring mistakes so I think we'll wait for iBasis to comment. You mentioned earlier you had talked to them and they would contact me to get this sorted out.

Hi Heidi,

The logs are attached near the photos.

Please check message again and there is the link with the file between photos.

Pls confirm that you find it.

I see. Perhaps iBasis Tech Support can comment on this issue, from a coverage standpoint. 

Again, to send a new device I will need to confirm that yours isn't working, which I haven't at this point.

I found the LTE Link Monitor from NRF Connect re-write the settings that I made with AT commands

 What do you mean by this? %XBANDLOCK and +COPS are being rewritten every 10-15 minutes?

Please a text document of the LTE Link Monitor log by pressing this button and attaching the file that pops up. The pictures of your computer screen were not very helpful.

 

Best regards,

Heidi

Hello Heidi,

I tested the device in several places and the response was the same. In 1 location it even shows 3 lines of signal, but no connection to network. After few seconds the signal disappear. 

I checked with Orange Romania and they confirmed LTE-M coverage in more than 3000 localities in Romania, including Bucharest.

Unfortunately, I do not have a solution to show LTE-M coverage in the places where i made the tests, only LTE as I already provided. If there is such solution, please inform me.

Also, I found the LTE Link Monitor from NRF Connect re-write the settings that I made with AT commands at each 10-15 minutes, forcing me to make the settings again.

At this point, the existing device is not working for me. I can test is with a new one, to eliminate the possible cause of the wrong firmware or radio module.

Hi again, I apologize for not responding earlier. When you mark an answer in your ticket as a Verified Answer, the employees on DevZone stop receiving notifications if the case is updated. 

Yes, as you can see here, band 7 is not certified yet, but band 3 is. In the Thingy:91 doc in Europe bands 3, 8, 20 and 28 are used. 

 

From your images, it looks like you're showing me the LTE coverage in that area? There is a difference between LTE and LTE Cat M1, the protocol that the nRF9160 supports, and good LTE coverage does not imply good LTE Cat M1 coverage.

Have you contacted the network provider to ask specifically about LTE Cat M1 or LTE NB-IoT coverage where you are?

Is it possible to test a device with a eSIM and to deliver to my company, either directly either through Farnell from whom i acqured the device?

 I'm not sure what it is you're proposing here. 

If your device does not work, we will, of course, send a new one. But let's pin down what the actual error is first. And you do not need to send us your device to receive a new one, if it isn't working. 

Best regards,

Heidi
