Why do you assume that IP addresses (client/server) are stationary? I uploaded the code and every time i got different IP from the NodeMCU. So how can I check "IP" from a NodeMCU so after changement from code of "checking IP" into a client/server code i will still get the same IP address?
Look here :
forum.arduino.cc/index.php?topic=460595.0
github.com/esp8266/Arduino/issues/1959
Your router gives new IP every time your Esp reconnects to router. That’s why you will always get different IP
Hi I made it, everything worked fine! One question please, can we make this led on and off without any delay? So if you turn it on, don’t wait to turn it off.
sir if the client is 2 how can we make the difference a message from client 1 and client 2?
Thanks for this video. Would this also be possible using a PIR instead of a button?
You're welcome :-)
Of course it's possible, you can replace the button variable with the PIR variable.
Thanks! Just a quick question. I managed to get the PIR working on this setup but there seems to be a delay before the led starts responding to the input. The delay is about 30-35 seconds which is too long. Any idea what is causing this and how to change? I tried a lot already
@@gruijl Do you only want to send sensor data?
Uteh Str yes indeed. Do you have a solution?
@@gruijl Take a look at this video: ruclips.net/video/mwsJUnrJPYI/видео.html , communication via UDP. Maybe it's faster.
i got the server ip but can't get the client ip....i use 2 different nodemcu s bt the result is same...... can't get the client ip...what should i do????
Have you followed all instructions on the video? Try repeating, maybe something has been missed.
@@utehstr the problem is solved.....😃😃😃these videos are so helpful for me thank you so much and keep it up
@@irfanayan2448 Congratulations 😃
You are welcome 😊
How did you fix it? Is it said that "Attempting connect to SSID" right?
hello there, can i replace the button with ultrasonic sensor?
First of all, Thank you very much, i have tried your work, and it works perfectly. But i want static ip address for Server as well as for Client, after making the static ip of both devices the client cant connect to the server! can you please tell me the reason?
we are not able to download the coad
Can you tell me how to open two windows (COM10/COM8)at the same time 。I can only open one of them and only execute one code.
Open the Arduino IDE by clicking on the desktop icon or on the program files or in the folder where you install the Arduino IDE, if it is already open repeat again to open the second Arduino IDE. Don't use File-Open or File-New to open the new Arduino IDE.
If when opening the Arduino IDE, then it displays the previous code or previous project, then:
Open the Arduino IDE then File-New, close the previous Arduino IDE. Reopen then File-New, close the previous Arduino IDE. If you do it correctly, two Arduino IDE will appear with the default code display (Void Setup and Void Loop).
@@utehstr A can't apply it on Mac ,I found how to do this, thank you very much ! :)
@@yuhe4088 You are welcome :-)
@@utehstr Can you tell me if I can control multiple servers through one client?
Can you made the same project without Wifi hotspot?
thank you so much
can i connecting between server and client just by wifi and without notwork ??
Sorry I don't understand what you mean, can you explain in more detail.
Yes, you will need to create Access Point instead of connecting to home network. Use sketch example called ESP8266AccessPoint in your Arduino IDE
Hello can this be used as many server and 1 client only? Can anybody help me?
The link is not working
Can you give any other link to download the audio
I have replied to your email.
I think there is something wrong with your get IP code. It keeps "Attempting connect to SSID" and i had tried to connect with another wifi but it didn;t work.
Make sure you use the correct SSID and password in accordance with your WiFi router / hotspot.
@@utehstr yes I did but it doesn't work. I only can check the esp ip by using server code
@@utehstr Sir your get_Ip code missing out Wifi.begin so it can't connect to the Wifi.
@@TungPham-ku7xf I will check it. thanks.
@@TungPham-ku7xf Are you sure that without "Wifi.begin" you can't connect to wifi ? I have tried without "Wifi.begin" and the results can be connected to wifi.
Whyy when i want to get IP first its take a long time second its write just " ????? " What should i do?
Remove “//“ in front of your WiFi.begin(ssid, password)
My name is indra from indonesia, thank's for this video, pelase help me, if i want to make LED on clients and button on server, and i have more then one client, for example : client 1 have 4 LED, Client 2 have 2 LED and client 3 for reading sensor and send it to server ??
How to send data of dht from client to server while server show the data of dht in serial monitor?
I don't understand what you mean, can you explain in more detail.
Ex: We get the data temp from dht which connect with esp client. Then data temp send to esp server and show data temp in serial monitor
is that possible to add more client?
Sir how to telnet mikrotik using nodemcu esp8266
hi can this project work with deffrent network
Que convertidor de Serial tiene ?

Help me, i cant find id of two esp
Can you send me the code by e-mail please? The link doesn't work seems it's damaged...
I checked the link and it was fine. But I will still send it to you. Write your email.
How to do the same over internet..?
I have never done that, but in theory it might be possible to use online servers or use IP Public.

Came across this link after searching.
Using blynk app. Pls try dis and expecting a video soon..
@@vinesha947 Thanks for the link, I'll try later.
Please send me this code because your link is not respond
Graaaaaaaaacias
De nada :-)
This link is not working
Which link doesn't work ?
fake down load link. google drive is empty
I checked the link and it's not empty.
Nope, not empty, maybe your head is. It is a .Rar file,
Arduino code download link not working bro..
If downloaded means unable to see the file.. can't open
I saved the Arduino code file on Google Drive with the .rar file format, Google Drive does not have a .rar file format viewer, so you must download it first. After downloading, make sure you have the software to extract .rar files, for example like WinRAR or you can use extractor .rar files online.
