* printed to Serial when the module is connected. * server_ip is the IP address of the ESP8266 module, will be In order to select the serial port which will be connected open the uP圜raft IDE and go to Tools>Serial and select the Com port for your Esp32. * Esp8266_server_ip/gpio1/3 will set the Green LED high, Similalry, you can download ESP8266 MicroPython firmware from this link. Or using Serial-to-USB adapter and connecting: VCC on Serial-to-USB adapter to VCC on ESP8266 based device. * Esp8266_server_ip/gpio1/2 will set the Green LED low, and then simply run tasmotizer.py (to find tasmotizer.py on MacOS you can use: find / -name tasmotizer.py) Connect your ESP8266 device to your computer either: Directly via the USB port on the device as with the D1 mini or NodeMCU. It is better to keep baud rate below 115200.

Remember that few USB to Serial converter does not support higher baud rate. Hardware Serial Programming is similar to the Arduino Serial. * Esp8266_server_ip/gpio/1 will set the Blue LED high, On ESP8266 we have one hardware serial i.e. * Esp8266_server_ip/gpio/0 will set the Blue LED low, * * The server will set a GPIO pin depending on the request Select the port shown on your side, in my case I got Com6. If you have not yet installed the libraries or setup the Arduino IDE for ESP devices, go ahead and check out my tutorial on how to configure the Arduino IDE for ESP devices. To fix error put a jumper wire between Ground and Io0 (IO Zero) to put the Esp8266-01 in the Programming mode Wiring Table

Wiring the ESP8266-01 only For Programming. Select the port number of your Serial adapter (Tools->Port) Enable programming mode on your ESP8266 as described above Click the upload button.

Arduino IDE option is intended primarily for software development phase. Such functionality became extremely useful in case of limited or no physical access to the module. How to programming esp8266 module with FTDI this is a Basic Project with the ESP8266-01 Module. OTA (Over the Air) update is the process of loading the firmware to ESP module using Wi-Fi connection rather than a serial port.
