Now you have a barebones ESP-01 programming adapter ready to work with Arduino IDE. The next step is to start your own experiments with ESP-01. For examples, the Arduino core for ESP8266 comes with ...

It turns out that there are different types of flash used with the ESP8266, and the correct programming mode must be selected for a given hardware setup.

A Protocol for the NodeMCU Lamp Controller To minimize complexity, I went with a simple program flow. The ESP8266 turns on, connects to my home WiFi network, then waits for UDP packets on port 10001.
