LSN50 LoRa Sensor Node User Manual 10 / 60
2. Use LSN50 with LoRaWAN firmware
2.1 How it works
The LSN50 is pre-loaded with a firmware and is configured as LoRaWAN OTAA Class A mode
by default. It has OTAA keys to join LoRaWAN network. To connect a local LoRaWAN
network, you just need to input the OTAA keys in the LoRaWAN IoT server and power on the
LSN50. It will automatically join the network via OTAA.
The diagram below shows the working flow in default firmware (Ver 1.6):
In case you can’t set the OTAA keys in the LoRaWAN OTAA server, and you have to use the
keys from the server, you can use AT Commands to set the keys in the LSN50.
