WIFI module ESP8266 - AT commands & sending Data to WebBrowser 

All I can say is, WOW! What an excellent explanation. The most clear that I've watched and listened to. Thank you.

Exactly, what I was looking for -- 2 way communication with ESP8266 using AT commands. Now, I can extend this for my home automation without using arduino or other boring stuffs.

Thank you very much for this great video, one of the best I have see on AT commands with detail explanation!

Greatest youtube tutorial ever made on this module, sir u reach d limit of explanation. Hats off & eager to get lessons like that in future, tanks in advance.

Fantastic video! I've been searching for a comprehensive, straight forward tutorial like this. Perfect, Well done !

Its 3 years later and still the best tutorial!

Tanks for the great tutorial! The best I've seen about the esp8266 about now. Greets from Austria!

Hello! Mr. SARAVANAN It was a pleasure to watch the video.

Very interesting subject Saravanan, very well presented. I keep in mind the little tips for my next videos focused mainly on the ATtiny 85 (and 84), I will start the ESP32 soon.

The lecture is simple and easily understandable.

Thanks very much Saravanan. I am finally getting success with my ESP8266 now. :)

I am just starting with IoT. I have a Cactus Micro which I want to connect to the network. This video was very helpfull to get me started. Thank you so much!!

Hi Mr.Saravanan, I communicated to you through this column 3 weeks ago. Thanks for your reply. I continue to face the problem of not able to join the wi-fi network in my ESP 8266-01. I am detailing the command sequence for your reference here:- 1. 9600 Baud rate gives garbage upon entry 115200 works OK. 2. All AT commands work OK upto AT+GMR . Gives firmware version as 0017090 3. AT+CIOBAUD? gives "ERROR" 4. AT+CWMODE? gives "3" 5. AT+CWLAP lists all access points 6. AT+CWJAP gives "no this fun" 7. AT+CIPMUX? gives "+CIPMUX:1" and then "OK" 8. AT+CIFSR=1,80 gives "no change "" 9. AT+CIFSR gives "ERROR" 10. AT+CIFSR? gives "no this fun" Can you sense what is going wrong ? With Warm Regards, S.Venkatakrishnan. 13-11-2016.

Thank you sir...very much helpful...This is my very first project of Iot...loving it

Dear Mr. Saravanan, very good tutorial. you have mentioned that RST pin shuld be pulled high. At some other tutorial I read it shoud pulled low. Which one is correct? or in both cases it will reset and high low does not matter.

Mind blowing👍 Great Tutorial with every step & details.

Dear sir, i am having esp-12e module.i can able to send data to http server. As you described in the video. but i want to send data to tcp ip server. while using the command at+cipstart="tcp","server ip',"port number". it is showing unlink. i dono were i got struck. please give some solution for this problem.....

Sir,can you please tell something about the circuit connection. I am currently working on ESP8266 and is not able to control and bring down the input voltage from 5v to 3.3v. Sir please help me out.. thanks

Your video is quite detailed and good. Explains the AT commands in their simplest form as well as you've covered a complete e2e experiment around ESP8266. Thanks.

Great walkthrough. Thanks for posting!

This was greatly useful video. Saved a lot of time during my project. Thank you!

Wow. Really clear and helpful. Thank you!

Muito bom trabalho ! Simplesmente muito show!

What if we send larger data instead of string? For example, pictures, can the MCU inside still process that fast? Or external flash should be add?

Hi When I want to connect Esp8266 to the wireless network with AT codes, I get MEM CHECK FAIL error on the serial port monitor screen. It is stated in some sources that esp8266 may be corrupted. Do you have experience in this regard? Or can you give me some advice? I wish you convenience in your work.

Excellent video and it works perfectly.... simple and clean tutorial.

Excellent tutorial! If I may ask, how do you get PUTTY to automatically insert carriage return (CNTL-J) on entering? I have played with the settings and have googled for the solution. Some google responses said it can't be done; but then I see that you made it work. So how is this done? Thank you for the tutorial!

Sir, I have PC with ESP8266 on one side, and it should communicate to my FPGA board connected to another ESP8266 on another side. I want to send/receive data to my PC running putty from FPGA board. Like at point 11:24 in ur video, is it necessary to connect through channel 0. How it will be done in FPGA ?

Really clear tutorial. Grazie

I am looking for information on using the ESP8266 12 in P2P mode. What I am trying to do is operate a relay remotely, through a non internet connected router. Am I on the right track with this device? I am competent with connecting IO to power circuits, just not so much with P2P (point to point). The specs say that it is capable, just no info to use it.

hello, can you help me? i have tried this, but when i type AT+CIFSR, there are only STAIP and STAMAC, no APIP and APMAC, and when i tried to open the browser and type my STAIP and port, nothing happens, not like what happened to you like at 8:26. Do you know why it happens? Thanks

Fantastic video my friend. Congratulations from Brazil 🇧🇷

THANKS FOR YOUR SUPPORT SIR, NICE AND VERY IMPORTANT VIDEO DEMO EVER.

Thanks a lot saravanan. this info was very useful for my project

Great video, thx.

​i directly connected my esp8266 with mega using 3.3v from mega and tx goes tx and rx is connected to rx, as soon as i power my auduino afer few seconds the blue led turns on and remains on. it did went of when i removed ch_pd from 3.3v. what is happining? for the same setup it was correctly working before, i have also tested few at commands but now the serial monitor remains blank .how to fix this? please help.

Hello Saravanan AL, I am working with esp8266 where i am receiving data through "esp8266" from a server using putty. The problem I am facing is that when I am sending data to esp8266 through server I am not receiving all the data in the string. for eg:- if I am trying to send "helloworld" through server, I am only getting "hello" in my string. my received string should contain "helloworld" the full data, but that is not happening. Can anyone help why this is happening? This is the process I've followed with esp8266 communicating via UART AT AT+CWMODE=1 AT+CIPMUX=1 AT+CWJAP="USSID","PASSWORD" AT+CIFSR (HERE I AM GETTING IP address of esp8266) AT+CIPSERVER=1,PORT NUMBER I am connecting to server using IP address of esp8266, Thank you in advance.

Excellent tutorial
