Flash AT commands firmware in ESP8266 ESP-01 device


The module comes with AT commands firmware when buy but you can flash other firmware into the module like NodeMCU etc. 
But if we want to reflash Espressif's AT commands firmware again in the Wi-Fi module it is very simple.

Do the following steps to download and Flash AT command firmware into the module:

1. Download Espressif's original ESP8266 Flasher.exe and ESP8266_AT_firmware.bin. Please click here to download.
2. Unzip the zip file.
3. Open ESP8266 flasher and add binary.
4. Connect ESP8266 ESP-01 with USB to serial converter. Connect GPIO0 to ground to put the module into flashing mode.
5. Click to flash the software.
6. Done!

How to put ESP-01 module into flashing mode:


Connect GPIO0 with Ground pin of power supply

      If you see at least AT then you set TERMINAL to send CR+NL, not only CR/NL.

      it should be like that... disconnect the GPIO0 off the GND and disconnect the usb from your pc.. wait for a couple of seconds and then plug the usb to your PC.... goodluck

    Binance account frozen error? This error might seem difficult but what actually difficult is to fix it which is out of the scope of a user who just has joined or holds less information about the exchange. If you are looking for ways and means to deal with this a bummer all at once, you can always call on Binance customer support number which is always functional. You can have conversation with them related to every type of Binance error and avail out-of-the-box remedies from the professionals in nick of time.
