16 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.

138 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.
