Change Network to NB IoT Service and Start MQTT

[azwawe]

Hi,

I was creating a Location Tracker, but using NB IoT Services. When I take a look on this example (Location Tracker), I can't connect to network.

00> *** Booting Zephyr OS build v3.1.99-ncs1  ***
00> 
00> Location sample started
00> 
00> 
00> Connecting to LTE...

It stuck on there.

So I was thinking that the card maybe using NB-IOT Network, not LTE-M. How do I change mode in configuration from LTE-M to NB-IOT? Thanks

Hi,

Assuming you are using the LTE Link Controller library to establish the LTE link, you can configure it to use the right mode by setting the right option in your prj.conf file.

To see which options you can set, you can go here, and enter "lte_network" in the search box.

Best regards,

Didrik
