585 585  
499 +LSN50-v2-D20 has an internal LED, it will active in below situation:
586 586  
587 -After added, the sensor data arrive TTN, it will also arrive and show in Datacake.
501 +* LED will fast blink 5 times when boot, this means the temperature sensor is detected.
502 +* After the fast blinks on boot, the LED will flash once which means device is trying to send Join Packet to the network.
503 +* If device successful join LoRaWAN network, the LED will be solid on for 5 seconds.
