Easiest Way to Upload Program in ESP8266-01 or ESP-12E

[@rehmanzed]

what if i use ESP12F

[@ElectroCreativity]

Same procedure will work for ESP12F. The ESP12E and ESP12F are essentially the same modules, but the ESP12F is an improved version of the ESP12E and has a better antenna design, which leads to better output power.

Does it write the sketch to both boards?

[@ElectroCreativity]

No . It does not write code to nodeMCU because it is disabled. If see the ckt, we have connected enable pin of nodeMCU to ground so nodeMCU will not be programmed. So program will be uploaded in ESP-01/ESP-12E.

Plz give the circuit diagram

[@ElectroCreativity]

Given at 2:00

@@ElectroCreativity 😂yah got it 👍

[@creativemind8573]

In your circuit diagram you controlled RX pin of esp 01 to RX pin of esp8266 and TX pin of esp 01 to TX pin of Esp8266 this connection type is incorrect

[@ElectroCreativity]

It is correct. ESP8266 on Node MCU is disabled, and we are bypassing its Rx-Tx pins to external ESP8266.
