They need to be provided to the ESP Flash Download Tool, together with the corresponding addresses (offsets) found in the readme.txt file above. The firmware is broken down into several files (e.g. Inside the file, there should be a “NON-BOOT MODE” section, as follows: esp_iot_sdk_v1.4.0\bin\at\readme.txt) file containing the information for flashing the firmware. QUAD 4Mbit).įrom the AT release folder, open the readme.txt (e.g. The size is shown in the “ DETECTED INFO” text area, in the “flash” section (e.g. After detection, you should see something like this:ģ Gather information. Start ESP Flash Download Tool, set the COM port corresponding to your FTDI programmer, then click the START button in order to detect the specs of the board. Download the latest AT release ( v0.50 at the time of writing) from here.Ģ Detect module parameters.Download the latest Flash Download Tools ( v2.4_150924 at the time of writing) from here.Keep this in mind while connecting the jumper wires, if you hold the board facing the pin header side towards you. Please note that in the diagram, the pin headers on the ESP8266 boards are on the other side of the board. This post addresses various problems that may appear when using the ESP8266 module.īelow, we have particularized the fritzing diagram for the popular ESP-01 module: an USB port instead of the FTDI output or an external power supply). In this case we recommend to use a step down voltage regulator, connected to a relatively powerful (e.g. garbage output at serial, random resets, repeated unsuccessful firmware updates, etc.), then it’s probably related to the power supply. REMARK ON POWER If the ESP8266 chip behaves strangely (e.g. from within Putty, or Arduino), these 2 wires should be removed.

For normal communication via serial interface (e.g. 3.3KOhm or 4.7KOhm resistor (pull-up resistor for CHIP_EN pin)Īs depicted in the diagram, the 2 wires at the bottom (IO0, IO2) are needed only when uploading the firmware.3.3V FTDI programmer or 5V FTDI programmer and voltage regulator.

SEE ALSO This post, for instructions on how to communicate with the ESP8266 from the PC, with PuTTY. Older versions (official or forks), are not really 100% compatible with the specs, and may even contain errors in the AT command syntax. HINT We recommend to upload the latest firmware right after buying an ESP8266 board.
