Wi-Fi Jammer using ESP8266-01? Is that possible? Well... YES, It is. If you can't afford a NodeMCU ESP8266 or you simply don't want to buy one, just follow this tutorial!

Note: THIS IS NOT A TOY! IT IS CONSIDERED ILLEGAL. Do not use it to hack wifis. This is for educational purposes ONLY!

Step 1: Connect Your FTDI With Your ESP8266

Connect your FTDI with your ESP8266-01 using this diagram:

ESP8266-01 -> FTDI

RX -> TX

TX -> RX

VCC -> VCC

CP_PD -> VCC

GND -> GND

Also DONT FORGET to connect GPIO0 to GND ONLY WHILE PROGRAMING!!!

ESP8266 use a logic level of 3.3 Volts for communicating. If your FTDI Chips can switch to 5v-3.3v select the 3.3v.

Step 2: Flashing the ESP8266

Go to https://github.com/spacehuhn/esp8266_deauther/rel... and download esp8266_deauther_4mb.bin or any other version you want (must be .bin). Then you have to flash it to the ESP8266 board using a flash program (I used ESP8266_Flasher. Link to it here).

How to Flash the ESP8266?

- Open the esp8266_flasher.exe

- Click on bin

- Find the .bin file that you download in the previous step.

- Select the port where the FTDI Chip is connected at

- Click on "Download"

NOTE: GPIO0 MUST BE CONNECTED AT GND WHILE DOING THIS STEP! DONT FORGET IT!!

At 99% or 100%, you will get an error. Ignore it. Your bin file was successfully uploaded to the ESP8266.

Step 3: How to Use It?

After you upload the bin file, your device is ready to be used!

You can also do the same using the Arduino IDE. I can help you if you want to see how to upload the program using an Arduino board (any type) and Arduino IDE.

Hope this tutorial helps you. Have fun!
