After this 200 Join finish, device will send a join request every 20 minutes. If device reboot, it will do above loop again.

136	136	There is a issue if the end node is fixed at sub-band2. The sensor won't be able to register to other sub-band and can only works for the LoRaWAN server use sub-band2 , such as TTN. To solve this, user need to use a USB-TTL adapter to connect to the end node to manually set the sub-band which is very inconvinient.
