Since I handle the basics of ESP8266 it does not matter what version is used here:Д®SP8266 ESP-01, ESP. This tutorial is made primarily for myself (to remind me of details in a few weeks time when I will have forgotten all how-to's) as well as for anyone else. when applying 3.3V to Vcc you can still safely apply 5V to the IO and TX/RX lines: these are 5V tolerant (this post directly from the boss of Espressif -maker of ESP8266- Teo Swee Ann: when using a development board (ie Node MCU) with an onboard USB connector then you can connect this board directly to USBДў. One important comment: NEVER apply more then 3.3V to Vcc. When you buy one of these make sure they offer the option to drive either 3V or 5V output.

The least problems I had was with the FTDI although the others do well too (just a bit more hassle to install the drivers). These little pcb's can be had on Aliexpress for a few $ each. Each has their own driver to be installed. These converters are mostly based on one of these IC's: CH340 (or CH341), CP2102 or FTDI.

If operating parameters need to be changed, you have to connect to the ESP8622 with a serial connection, using a USB to serial converter.

what are the pro and contra of the various methods, parameters.ДЄ very good starter is with a book available for free (although the author asks for a reasonable and well deserved 4 to 5 USD, so if you can afford it: it is money well spent): how can you change these function parametersДЈ. Numerous 'recipes', often contradicting each other or themselves, often written with the best of intentions, but then only a few webpages did really offer usefull information, at least for my purpose:Дў.

Honestly, I did sweat several days and nights through countless fora, websites, blogs. So started my quest (because that was what it was) to find ways of altering this 'black box' functioning. But if you work with a Pro Mini, or Uno, then you only have one hardware port and I needed the hardware port to interface with other peripherals. In effect restricting me to use the hardware serial port.

But the ESP8266 has a fixed baudrate of 115200 (using the more recent firmwares the originals, years ago, would make the ESP8266 transmit at 9600 baud). However, this library is not reliable beyond some 38400 bauds. No way to change operating parameters such as baud rate, deep sleep, etc.ДЇor example, in the projects I want to use the ESP8266 I need the SoftwareSerial.h library.

As soon as I wanted to change the operation of the ESP8266 I ran into a wall. Some experimenting with an ESP8266 using the Arduino IDE left me with too much a feeling of handling some black box. Very quickly I came across the ESP8266 module. After a year or so of experimenting with Arduino I wanted to take it to the next level ie.
