228 The LSN50v2-S31 is working as LoRaWAN OTAA Class A end node. Each LSN50v2-S31 is shipped with a worldwide unique set of OTAA and ABP keys. User needs to input the OTAA or ABP keys in the LoRaWAN network server to register. Open the enclosure and power on the LSN50v2-S31, it will join the LoRaWAN network and start to transmit data. The default period for each uplink is 20 minutes.
