259 259  The PS-LB 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 need to input the OTAA keys in the LoRaWAN IoT server and activate the PS-LB. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.
