ESP8266 Community Forum

Good day to all of you in this forum,
I have to connect to MCU's using the wifi instead of normal wiring harness.
The MCU' is powered at 3.3V as the two ESP's. The MCU's have an UART I/O available.
UART configuration is 9600 , 8 , n , 1 . The transmission rate is slow.
I have attached an hand drawn diagram to better clarify the layout.
I will appreciate very much to receive any indication and suggestion on how to implement the software.
Thanks in advance for any help on the matter.
Regards,
Ambrogio

You can start your project by looking at Erik's Bridge https://github.com/eriksl/esp8266-universal-io-bridge
Then adapt it so that you have 2 ESPs, one as AP and the other as STA.

I think esp-link provides what you're looking for https://github.com/jeelabs/esp-link

Yes, that's look good too !
