Is there an app that finds all receivers/transmitters on 2.4Ghz?

I know that wifi operates at a frequency of 2.4Ghz. There is a quadcopter, which also operates at a frequency of 2.4Ghz. Is there an app that finds all receivers/transmitters on 2.4Ghz? Lost quadcopter, need to find it. Maybe there is such a device that finds other devices at this frequency and shows the distance to them?

The quadcopter most likely has already landed and is not broadcasting anything.
Unfortunately, there is no such application. This is a special radio device. Such devices exist, but they are expensive.

2.4Ghz is an approximate frequency. The same wifi has 13 channels, working, albeit at close to 2.4, but still at other frequencies. Moreover, not 1 frequency is used, but a whole band of 20\40 megahertz.

to find a directional antenna with 15+dBi
u.to/wm3gDQ , the spiral version looks the easiest to manufacture, but here you also need to take into account the wave impedance - to fit the receiver.
programs that display the Wi-Fi signal in decibels can be found
at www.winline.ru/articles/6_poleznyh_utilit_dlya_rab...
the distance will be very conditional, but at least the direction can be determined
most likely by the time everything is assembled the copter will be discharged and stop beeping
UPD is provided that we are looking for a wifi access point, if not, then at least an exotic firmware and it’s not a fact that such a thing exists or is possible in principle, the more reliable option seems to be to attach a 2.4 GHz amplifier to a directional antenna and look for the signal level on the voltmeter (only at 2.4 GHz there is a lot of garbage and self-collection will take a lot of time, and special equipment is ah ah how expensive)
