Most handheld R/C controllers operate at 2.4Ghz. I'm wondering if it would be possible to "listen" to their output. The data is one-way only (TO the ESP32), and would probably have to be done in a "promiscuous" mode, since the R/C controllers are usually "bound" to one receiver only. My application would require that it be able to receive the data from a transmitter that was already bound to a receiver. Hopefully, a way could be found that would allow the ESP to listen to only to a specific transmitter even if there were many in the vicinity.
Has anyone done this?
