Product Description

The LT-22222-L is configured as a LoRaWAN OTAA Class C mode device by default. It has preset OTAA keys to join ant LoRaWAN network. To connect to a LoRaWAN network, via  LoRaWAN gateway, the user needs to input the OTAA keys in the LoRaWAN network server and power on the LT-22222-L. It will auto join the network via OTAA.
