NB-IoT 04b: Basic connection Cat-M

This example shows how to switch on the NB-IoT module connect it to the network and get the operator name.

Required Materials

1 x Waspmote 1 x Battery 1 x NB-IoT / Cat-M module 2 x NB-IoT / Cat-M antenna 1 x SIM card

Notes

- The battery has to be connected. - This example can be executed in Waspmote v15
