Is it possible to use a pi zero as the base station? #13

Apologies in advanced im not to experienced with this kind of stuff but I wanted to make an rc car/tank. With the current unavailiablity of pi 4s I was wondering if it would be possible to use a pi zero that I have lying about.

Additionally can data be sent back to the esp32? It would simplify my project if i could control the car with a controller or something plugged into the pi.

I think you could use a PI0, but you still need an USB wifi adapter. As far as I'm aware, the wifi on the PI0W doesn't support monitor mode so you need the TL-WN722N for that. Yes, data can be sent back to the esp32. Communication is bi-directional. ATM the base station only sends a config packet with camera related stuff like resolution etc, but there is also a data packet with controller things. It's not handled in the esp32 side - that's something you'd have to do yourself.
