As mentioned in the previous post , in this post I'll show you how to upgrade the firmware of the ESP8622 wifi module.
To do this first we need to download the firmware.We can download the firmware from below link.

Then we need to connect the GPIO0 pin to the GND.
  Then open the downloaded flasher file. 

Then as above image,

  • Select the downloaded firmware by clicking the "Bin" button 
  • Type the port number
  • Upload the firmware to the module bu clicking the "Download" button 

After that you can see the data writing to the module by blinking blue color led in the module.

 Then the downloading will stop from the 99% , in that time we need to close the flasher & disconnect the GPIO0 pin from the GND.

Then open the Arduino IDE , and select the COM port.Then open the serial monitor and set the baud rate to 9600/115200.Then type the command as "AT+UART_DEF=9600,8,1,0,0" and hit the enter button.This will change the baud rate into 9600 of the module.

In next post I'll show how about NRF24L01 RF module.
