ESP8266 flush program after power lost

I program my ESP8266 with a Arduino Uno and this guidance: Programming the ESP8266 With the Arduino IDE in 3 Simple Steps

Wifi connect, Mqtt connect (subscribe, publish, callback) everything works fine and totally like expected.

But after I disconnect the power from the Arduino Board and reconnect to a another V3.3 power source, the ESP8266 behavior is like a complete clean flushed device and nothing happens.

For programming I use this settings (Arduino IDE 1.8.12):

What I am doing wrong here?

EDIT

1.) I try two different ESP8266, and 3 different scretches (1. proved working in the past, 2. simple blink sketch, 3. sketch with my code I need)

2.) the program stops immediately after disconnecting CH_PD from 3.3V

3.) I update the esp8266 board package to the newest version 2.6.3

Solution

  • The main issue here is my bad documentation. After a long time, I found the solution again here: Easiest ESP8266 Tutorial (Using arduino). Like the first time two years ago. In conclusion, I forgot to disconnect GPIO0 from GND after programming.

    The correct way after programming is:

    • disconnect arduino
    • disconnect gpio0 from gnd
    • connect power to esp8266
