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.
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.
Thanks for your "Extra Boost" appreciation. As of now NodeMCU module built on ESP12E has become the cheapest & best IOT platform I've started tutorials on it.More to follow : th-cam.com/video/BbiLBiFvlsI/w-d-xo.html
Sir, It's my pleasure to support genius like u, One thing I noticed from that videos is," knowledge is precious thing which u always ready serve other". & thnk for ur precious time given by u to reply my comment.
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!!
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.
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.
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, 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 ?
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
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.
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
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.
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!
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.
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.
sir, my laptop keyboard not working with putty and i m also not getting any response when connected(getting one character garbage value) and i have resetted it many times

Hi, I have build midi controller with 12 buttons and it works fine with my ableton live 9, I using Arduino pro micro for this, now i have new challenge to connect this via esp8266 to my computer and continue to use my midi controller without USB cabel. Is it possible ? thanks
thank you sir for the tutorial , I have a question.... will the station IP be the same every time I turn on or restart the module or it is going to change?
ESP module remembers the joined AP & the STAIP will be same till you quit the AP using AT+CWQAP. Even if you remove power for days your ESP will remember the AP.
Thanku for the tutorial i had faced one problem, i had opened the putty and selected the com port, after that nothing had shown in the screen, as per your instruction i had reset the esp8266 and came some garbage. after that nothing , i cant even type the AT command not showing anything in the screen. plz help me sort out the problem ,waiting for your reply

THANKS FOR YOUR SUPPORT SIR,
NICE AND VERY IMPORTANT VIDEO DEMO EVER.
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?
Which mobile app you have mention at last moment of video ??

Hi, I have build midi controller with 12 buttons and it works fine with my ableton live 9, I using Arduino pro micro for this, now i have new challenge to connect this via esp8266 to my computer and continue to use my midi controller without USB cabel.
Is it possible ? thanks
thank you sir for the tutorial , I have a question.... will the station IP be the same every time I turn on or restart the module or it is going to change?
ESP module remembers the joined AP & the STAIP will be same till you quit the AP using AT+CWQAP. Even if you remove power for days your ESP will remember the AP.
You can also use this AT command to change IP :
AT+CIPSTA=”192.168.1.5”
Now your STAIP of ESP is 192.168.1.5
this is a good way to do this , thanks
Can you tell the Https at command request in ESP8266?
