What is the difference between the 2.4 wifi and the 2.4 radio that the RC models use? Could you use the FPV goggles to recieve the ARDrone?
Thanks

Hello,

the frequencies are similar but the main difference is the protocol. You can not use unmodified FPV goggles to receive the video stream of the AR.Drone.

Sweet and delicious apps for your drones.

If you put a 5.8 FPV transmitter and camera on AR Drone would it interfere with drones WIFI?

Probably not much interference.
  • The downside is you will not see any of the drones telemetry downlink data in the 5.8ghz goggles. (eg battery level, air speed, altitude, etc)
    Plus... the AR Drone would be carrying more weight and bulk.
About the AR Drones data links:
The AR Drone uses qty 3 IP Ports to communicate with the phone-control-device:
  • UDP Control Uplink <-- (control data packets are sent around 30 times per second)
  • UDP Telemery Downlink <-- (telemetry data packets are received around 30 times per second)
  • TCP Video Downlink
  • Notes:
    • if only a few of the qty 30 Control Uplink data packets get to the drone per second then it's controlled flight is maintained.
      if only a few of the qty 30 Telemetry Downlink data packets get to the phone-device per second then the drones status (battery, level airspeed, etc.) are updated onto the phone-device screen.
QUESTION: What kind of phone-device do you use to control the drone ?
  • If your phone type device can output video as an HDMI output then you can purchase a headset display that accepts HDMI.
    Note: The USB connector on some devices can output HDMI by using an adapter cable.
    If it is possible to use an HDMI video headset with your phone-device then you will also see the telemetry downlink data too.
