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.
