59	59	* OTAA: Over the air activation. In this mode, the end node will send a Join Request to server, server will reply with a Join Accept and the end node will parse this Join Accept message to get the Dev Addr / APP Session Key(AppSkey / Network Session Key(NwkSKey). Because the AppSkey and NwkSkey is dynamic, OTAA mode provide more security.
60	60	* ABP: Activation by personalization. There is no hand-shake with LoRaWAN server for activition. The end node will use fix Dev Addr / APP Session Key(AppSkey / Network Session Key(NwkSKey) to upload the packet. So the packet can be decode if someone know these fix keys
