Hello Mr Santos. I have an stack in ESP32 Camera board, when iam upload WiFi camera access in example software Arduino 1.8 then code error ............ Can you help me ?
THIS IS EXCELLENT!!! So many Tuts require a router network. I can figure it out, but it would be nice to see how you can "CONNECT" and use a browser to collect this data from say a laptop, or Android phone. Very helpful info here!! Great work!
You would need to make your laptop/smartphone connect to the ESP Access Point, then open the ip address followed by /temperature (to see the temperature). You could also setup a web page in your board that would display all those readings at once
Pretty neat. I see you make three separate calls in yr asynchronous website, for temp,humidity and pressure. That makes it simple and very clear, but ofcourse also possible to make it with just one call
Thanks for the great video! I have a question... I see the client requests data and the server replies with the three requested values, but is there a way to also enable the server to request data and the client replies with some values? I have a need to initiate requests from both sides.
How do this guy know what I'm doing 😳 Everytime I struggled & finish a project he publish exactly same as a tutorial. Last week only I needed it hardly & finished it at last. Now you made an easier tutorial.
Hi Rui, i am not trying to flatter you by any means, your tutorials are THE BEST in there respective topic. About the topic at hand, lets assume that i live in a community without internet connectivity, can ESP32 Server such that you demonstrated act as an AP to control something like 8 channel relay?
Thanks for the video Rui. Quick questions: 1) When ESP32 creates an AP, will the IP address be the same always? 2) how many other ESP's can I connect to the Master ESP AP ? 3) Will the Master ESP still be able to get connected to WiFi while it has it's own AP simultaneously?
ESP32 question: I need to connect via I2C: BME280, BNO055 gyro, L53L0X TOF Time-Of-Flight, and optionally an OLED 128x64, I read I need to add pull up resistors. 1) would there be pull up resistors already on these modules? 2) would each sensor need 2 resistors for data and clock, or would you only add a set at the end of the "chain" like termination back in the SCSI days? Thanks:-)
Hello Rui, excellent tutorial. I have a question. Do you have an example with let's say client has just one push button and server has an led. The same like in this tutorial, with no router. Press the button on client and led turn on on server. Even more. Each board has an push button and each board has a led. Same principle. One push button turn on led on the other board. I love to see something like that. Thank you
What's about changing the roles of server and client? Would be much more logical for me. So when connecting to multiple sensor stations you have the one with the display and multiple clients on different locations.. Or is it still the client with the display that ist permanently pulling from different servers (per definition)?
i've been trying to make the same project but with using MPU 6050 sensor but i keep fail. can you please do a tutorial for this sensor too? I fail to do the String line and using the MPU 6050 library from what i think it does not support String or i do not know how to do it. this is an amazing project! thank you soo much!
Hi. Two questions: 1) the IP needs to be get manually every boot? Since the client needs the IP of the server, can it be pre-set? 2) In this case the server sends data to the client. Can you show an example in which two clients send data to one server?
Great video, but I have a question...can ESP32 communicate with 2 methods at once? for example like ESP 1 - ESP 2 with ESP-NOW, then ESP 2 - PLC with wifi communication...
Can client send data to server as well simultaneously? I want to send data from server to client and at the same time want to send data from client to server. Is it possible?
I don't mean to be negative, but isn't this setup a bit back-to-front? What I mean is, wouldn't it make more sense to have the Client connecting to the Server's Access Point, but put the sensors and API on the Client module, and connect the display and issue GET requests from the Server? That way, it would be trivial to add extra Clients running the same code and simply modify the Server code to GET from additional IPs/URLs. I might've misunderstood the tutorial, but it seems to me that if you wanted to add additional ESP+sensor client modules to the setup as demonstrated, you'd either have to configure them to connect to the first sensor's access point and then add a bunch of extra endpoints to the server code, or else configure the client to somehow keep connecting to and disconnecting from different APs (I've no idea how you'd do that). Either way, it's extra code, when surely the aim in such projects would be to maximise reusable code and minimise rewrites. Or am I missing something here?
@Rui Santos with asyncwebserver is possible this function,? 1 connecting by router 2 if server have data send direct to client? I have test your part code and need sugestion for my complete my project. Your code have problem for working with router installed to my hardware. And work only m2m without router. I have send two post to your website blog. Thanks
I have several 8266 clients speaking to a server. Now I need more I/Os. I bought a ESP32 for the server. But now I can not communicate between them. It is difficult to do that?
Hello, could the time between sending of data right be reduced right? I am thinking of making a Wemos D1 Mini-based RC controller to control my Wemos D1 Mini RC car
Hey, this tutorial is great and very useful! Can you please make one tutorial on ESP-NOW, or if there is no difference between this tutorial and esp-now?
Hi there, great job! I have just started learning arduino and esp32, and I have a project I think which is way over my actuel grade! So if you are ok, I would like to hire you for my project! Let me know what you think!
Hi, sorry if the question is stupid, I'm new to the field 1:47 A white window with the name of the port to which the board is connected What is the name of this window and how do I get to it?
hi, Bro. I want to control the light by the client on the webserver. but i do not know to make id for the client to control. can you help me? Thanks bro.
can someone tell me if it is possible to use a encryption algorithm or something and secure this communication? is it possible with esp32 ? pls reply me if you know how to do it?? pleaseeeee i need helppp

I suggested keeping them close to test to ensure that they establish a communication. However, with this exact project using ESP32 boards and in open space (no obstacles) I was able to get up to 50 meters (164 feet) reliable communication

I'm trying to connect two esp8266 using server and client protocols and sending the data to thinkspeak server. Help me please 🥺
What can be the maximum distance?
Hi sir, i just want to know the max. range in which these two can communicate without any issue
Great example Rui, really useful I'd really like to see the same communication (print data) via Bluetooth for low power applications.
Perfect, just what I needed, thank you Mr Santos.
Thank you for your Camera Project you are doing incredible stuff
one of the best tutorial in esp32 in the youtube i saw, very well represented
faux it's not good pd
Many tips in this project, excellent ! Thanks a lot !
Excelente artigo ! Vou usar como ponto de partida em um projeto meu. Muito obrigado, Rui !

For the client any reason you choose ESP8266HTTPClient and not asynchroneous?
Are you aware that going to your website, makes high cpu usages?
Bro make more videos on esp32 and audrino ..i am happy i got new channel for this
Great as always 👍👍👍☺
Thanks!
Fantastic tutorial! I was wondering, would it be possible to connect more than 2 devices together and make a sort of little network?
Of course, just use one as a Access point and other devices as Stations.
Great video
Muitp bom!obrigado pour partilhar.
great porject gj
Thanks alot, can i do it with esp node mcu 32s and arduino mega using wifi module
Can we get it to do two things at the same time like deauth and monitoring ?!
What about using ESP-Now as well? That is something I watched in another video doing something similar
Very nice! Thumbs up! 👍
Thanks for watching!
does it also work with an all in one esp32 module? (OLED soldered on board)????
Hi Rui Santos, how to add relay at client side and turn ON/OFF from server side ?
that's possible to streaming wiedo to other ESP32 by wifi? Or exist way, to plug other esp32 by wires?
Running this gives me a 1 or 2 sockets transmission per second. Is there a faster way to make 2 ESP8266 boards communicate?
i've been trying to make the same project but with using MPU 6050 sensor but i keep fail. can you please do a tutorial for this sensor too?

Hi Rui Santos, can you pls make a video on how to send 12 sensor data serially from nodemcu to arduino uno and parse it?
Hi, nice tutorial.
What is range of this comm, if its couple of meter isnt then better to use BT?
Thanks for sharing.
With this project using ESP32 boards and in open space (no obstacles) I was able to get up to 50 meters (164 feet) reliable communication
@@RuiSantosdotme Well that is respectable distance, thak you for your fast answer.
Would this also work if the esp is mounted somewhere and then it sends data to my laptop via wifi using sockets?

Boas. Parabéns pelos videos de qualidade Rui.
Qual é o alcance de comunicação?
Obrigado
Boas, conseguiu um alcance de 50 metros entre 2x ESP32 num espaço aberto (sem obstáculos)
Rui Santos Parece-me bem.
Obrigado pela resposta
