Hello guys.. in my previous posts I have mentioned some of the AT commands to configure your ESP and establish a communication between server and client locally. In this post I will mention how to do the same using PuTTY and Realterm.

Configure your ESP8266-01 and connect to an AP and get the IP address using the command:

AT+CIFSR

1. Open PuTTY

2. Select “Telnet” as the connection type

3. Type the IP address and the port number as 80

4. Click on “Open”

A new terminal will open.

Now to configure Realterm

Open Realterm and migrate to Display and select baud rate and PORT

click Open and move to Send and do the setting as shown below

Send AT Command to check the response

Further to send command click Send ASCII Button

Put forth all these commands to reconfigure or to reassure

AT+CIPMUX=1
AT+CIPSERVER=1,80

Then migrate to the PuTTY terminal and type your desired message to print into Realterm screen.

This time you are sending message as a client to the local sever.

Now to send text message from Realterm to PuTTY follow these steps:

Open PuTTY and set connection type as Raw

Always after opening Realterm configure your ESP8266 there is no harm in doing this

You may get this message in return that ‘Link is built‘

Now type this command on Realterm terminal

AT+CIPSEND=0,5

And after this, type your desired message but it should be under the prescribed bytes which you’ve already mentioned in the above command.

And immediately you will notice your message on PuTTY terminal and this time don’t use:

AT+CIPCLOSE=0

which we have done when we are viewing messages on browser else this will close the PuTTY terminal.
