Can I use 8266 or ESP32 as an UART/WIFI/UART bridge?

I want to send data to and from my car as easily as possible (when the car is parked). A DUE in both ends and some of those cheap modules could work fine. But what about the software. Does anybody know a good site or a link to do that.

What about this?

Thanks. Now I have to learn how to flash them although I tried to avoid that.
