501 +* Uplink self-status to the LoRaWAN server every 30s. the users can adjust **Keep Alive Period** as below
502 +* Check LoRaWAN server status every 5 seconds to see if there is valid downlink command to sensors. We don't provide WEB UI option to modify this time, because the modify of this settings will lead to fail on OTAA Join and Downlink commands.
374 374  
375 -//For this case, by default, the gateway will uplink self-status to the LoRaWAN server per the 30s. the users can adjust the interval time.//
