40.2	187	The SDI-12-LB is configured as (% style="color:#037691" %)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 SDI-12-LB. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.
