Hi

The GSMA deployment map, https://www.gsma.com/iot/deployment-map/, shows where NB-IoT and LTE-M is available. If you location is not listed there then I do not think that you will be able to connect your device.

The question that the cell provider should answer is if they support NB-IoT or LTE-M on their network at your location. Or ask them when they will provide such services.

Are you using the mac? if so then you should be bale to find the log file under, /Users/nordic/Library/ApplicationSupport/nrfconnect/pc-nrfconnect-linkmonitor/logs and open the file this way.

I am not currently in Brazil, I am in Venezuela. In concrete, what is the question I should ask to my GSM operators to know if I can use this device in Venezuela?

The app cant access the log file for some reason, let me try to fix that problem and get back to you with the log.

Hi Daniel,

I do not think that the issue stated in the blog post is the issue.

So could you give me your log from the LTE Link Monitor when you test the AT Client.

in the lower left of the program there is a button that will provide you whit the log file. (See picture below)

Also what SIM card are you using and have you activated the SIM?

Currently according to the IBasis website, NB-IoT and LTE-M is not supported in Brazil.

Here is a link to the GSMA Deployment map, the operators listed here should provide a SIM that will work.

Regards,
Jonathan

The issue has not yet been resolved. The device still wont connect to the network.

I left the device trying to connect to the network for some time and it is still not connected.

Could this be the issue?

I loaded the file from "full" folder and the terminal is now responding correctly, and the LTE flashes yellow-red just like yesterday.

I uploaded the modem firmware as such:

Then programmed the device with .hex image for at client located within the downloaded file.

Terminal:

Modem is non responsive. Yesterday I was trying to get it to work, and the terminal was flashing LTE yellow-red. however it never actually connected.

Jonathan thank you for your help!

I have the latest modem firmware to date (1.2.0), however I will try downloading and programming the device with the files you are suggesting.

I have DK 0.8.2

Hi Daniel,

Have you tried the latest application and modem firmware? (nrf9160dk_at_client_2020-04-29_bc7ade8b.hex and mfwnrf9160120)

NB: when choosing hex file select the one from the full image folder.

You can program the nrf9160DK using the nRF Connect - Programmer.

Pleas update the Modem and try the latest AT Client example, then use the newest version of nRFConnect for desktop LTE Link Monitor to check if you are able to connect to any network.

If successful it should look something like this:

Now if you want to connect your device to the nrfCloud then you have to load the asset tracker example.
If you all ready have the device registered to your nrfCloud account but it is still not working try the following:
Update certificates

What version of the DK do you have?

Regards,
Jonathan
