#88721 Could anyone please suggest how to connect the ESP-WROOM-02 module to an MCU through UART and program the ESP-WROOM-02 by Arduino IDE through the same UART port. ... c.png?dl=0

I am running a web server application inside the ESP-WROOM-02 and access it through a browser by an IP address. Also, created a message format to exchange the data between MCU and ESP-WROOM-02 through an UART which is same as used for programming the ESP-WROOM-02 by Arduino IDE when required.

I understand parallel UART communication is not recommended, but here there won't be any data exchange between ESP-WROOM-02 and MCU over UART during programming from the IDE.

Please advice.
