NRF9160 LTE NETWORK THINGS MOBILE ITALY

[Funyc]

I PURCHASED A SIM OF THE THINGHS MOBILE BECAUSE IBASIC DOES NOT WORK.

I HAVE LAUNCHED ASSET TRACKER AND THE NRF9160 DOES NOT CONNECT. LTE FLASHES IN YELLOW.

IS THERE A PROCEDURE FOR THESE SIMS?

Hi Nicola,

First I would recommend you to update the modem firmware to the latest version: v1.1.0

Since Italy does only support NB-IoT at the moment you need to start the modem in NB-IoT mode. (it defaults in LTE-M)

Please send the following AT-Commands:

AT+CFUN=4
AT%XSYSTEMMODE=0,1,1,0
AT%XEPCO=0
AT+CFUN=1

This will set the modem in offline mode, then switch to NB-IoT tech. and also say to the modem to use legacy PCO (since some networks do not support ePCO)

Best regards,

Martin L.

Thank you. It works.

But is there a way to connect it automatically without having to send the at commands?

How should the program be modified?

Hi Nicola,

Please check out our samples in the NCS.

Most of them utilize the LTE Link Control driver to connect automatically to the network so please use the samples as reference.


Please check out the NCS tutorials for more information and on how to use it.
