To connect a local LoRaWAN network, you need to input the OTAA keys in the LoRaWAN IoT server and power on the LSE0150. It will automatically join the network via OTAA and start to send the sensor value
111 +The NSE01 is equipped with a NB-IoT module, the pre-loaded firmware in NSE01 will get environment data from sensors and send the value to local NB-IoT network via the NB-IoT module The NB-IoT network will forward this value to IoT server via the protocol defined by NSE01.

134 +* Your local operator has already distributed a NB-IoT Network there.
135 +* The local NB-IoT network used the band that NSE01 supports.
