Network issue to work with nRF9160 in INDIA

[Nikunj]

Hello,

I followed getting started guide given in the link below,

https://devzone.nordicsemi.com/tutorials/b/getting-started/posts/getting-started-with-nrf9160-dk

I started with "asset_tracker" default example and also activated iBasis SIM on nRF cloud. LED3 started flashing but LED4 not even after wait of 30 minutes.

I setup SDK successfully then flashed "at_client" for debugging I observed it stucks at LTE network searching.

I also tried with local operator's LTE SIM but it shows the same.

Thanks and Regards,

Nikunj Panchani

Hi Nikunj,

Based on iBasis network coverage it does not mention India, or more importantly that LTE-M or NB-IoT support has not yet been deployed in India: https://www.gsma.com/iot/deployment-map/

So when using the iBasis SIM in your smartphone it was using another technology than LTE-M/NB-IoT to communicate.

If the first things I mentioned where not the case I would have recommended: 

You to to update to the latest modem firmware version: https://www.nordicsemi.com/Products/Low-power-cellular-IoT/nRF9160/Download#infotabs

Then I would really like you to run the at_client with LTE Link Monitor, and if it still has issues please provide the log from the output terminal.

Best Regards,

I flashed modern device firmware and at_client example to debug. I found that LTE in screen always shows yellow that means it is in LTE network searching mode but network is not coming even after wait of 30 minutes.
