2.4 GHz scanner based on ESP32 Wifi module
Posted: Tue Dec 20, 2022 6:23 am
Hello everyone
I'm trying to implement RF scanner for 2.4GHz. There are a lot of examples how to scan well known 16 Wifi channels with ESP but is it possible to scan non-wifi 2.4 frequencies (like RF toys controllers, microwave ovens)? I've played with NRF24 which can scan 128 channels but it doesn't fit because it cannot measure signal strength properly (it only says if the signal is higher than 64dB). I suspect Cywm6935 chip can do something like this but these chips are too expensive and out of production...
Is it possible to solve that task with ESP32? Thanks for any information

But the overall idea was great
