Hello,
So I have a quad copter (DJI Phantom 2) that I can fly using a 6 channel 2.4 GHz transmitter. From what I understand, each channel controls a certain component of the quad copter. I want to build an external circuit that will 'listen' for activity on a specific channel. What is the best way that I could detect if a particular channel is being used?
Also, each one of the six channels is actually a specific frequency correct? If I could find out what the frequency of my channel of interest is, could I just build a simple bandpass filter to filter all but that frequency out and then from that detect if the channel is being used?
Finally, I heard that these 2.4Ghz transmitters tend to preform frequency hopping, so does that mean that a given channel's frequency will constantly be changing?
Thanks for any help,
James
