We successfully connected NB-IoT network on nRF9160 kit in NB-IoT simulation testing lab, but it disconnects with network after sometime. We disabled PSM mode and that improved the connection time but still after 2 – 3 minutes Nordic kit left the network automatically. We tried no. of times, but each time Nordic kit left the NB-IoT network after 2 -3 minutes.
We want to know the reason Why Nordic kit left the NB-IoT network after 2 -3 minutes even with PSM mode disabled? Is there any other sleep mode that creates this issue? Please suggest.
