15 For 005 LoRaWAN stack: to save battery, once boot, device will make first make 200 tries for OTAA Join, the time period of two Join Requests will depends on the DR and the airtime requirement. After this 200 Join finish, device will send a join request every 20 minutes. If device reboot, it will do above loop again.
