132 132  The LT is configured as LoRaWAN OTAA Class C mode by default. It has OTAA keys to join network. To connect a local LoRaWAN network, user just need to input the OTAA keys in the network server and power on the LT. It will auto join the network via OTAA. For LT-22222-L, the LED will show the Join status: After power on **TX LED** will fast blink 5 times, LT-22222-L will enter working mode and start to JOIN LoRaWAN network. **TX LED** will be on for 5 seconds after joined in network. When there is message from server, the **RX LED** will be on for 1 second.
