Unmanned aerial vehicle system and method

A communication method to be executed by an unmanned aerial vehicle system, wherein the unmanned aerial vehicle system includes an unmanned aerial vehicle and a remote controller, the unmanned aerial vehicle includes a first communication unit configured to communicate with a first private communication protocol, a second communication unit configured to communicate with a first standard communication protocol, and a first controller unit, and the remote controller includes a third communication unit configured to communicate with a second standard communication protocol and a first communication interface configured to communicate with a user device, the method comprising:

• determining, via the first controller unit, whether the unmanned aerial vehicle can pair via the first communication unit with the remote controller;
• when the unmanned aerial vehicle cannot pair with the remote controller, sending out, via the second communication unit, pairing information of the unmanned aerial vehicle and version information of the first private communication protocol of the first communication unit;
• determining, via the second controller unit, whether the remote controller can pair via the third communication unit with the unmanned aerial vehicle;
• and
• when the remote controller cannot pair with the unmanned aerial vehicle, sending out, via the first communication interface, pairing information of the remote controller and version information of the second private communication protocol of the third communication unit.
