one of the best tutorial in esp32 in the youtube i saw, very well represented

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

Many tips in this project, excellent ! Thanks a lot !

Excelente artigo ! Vou usar como ponto de partida em um projeto meu. Muito obrigado, Rui !

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!

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.

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?

video simple,, complite, informatife, and something new

Thanks, Great job always The Source code with all comments is very helpful

Very nice and simple to remake!

Great Video Rui, just what is the maximum range between the two boards?

Great project! I was looking for something like this to create a simple remote control for my camera slider project 👍 Thank you

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

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.

great. Master advice for e-money projects

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?

excelente video Rui. Obrigado!!!

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

thanks for the video.; it helped me a lot. im just getting into these things :)

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:-)

good work. can I also connect more than two clients? for example a server and 3 clients?

Thanks. For the client any reason you choose ESP8266HTTPClient and not asynchroneous? Are you aware that going to your website, makes high cpu usages?

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)?

Hello, do you believe it is possible to connect a Rasperry Pi to the "server" esp32? Thanks & great vid!

Thank you for tutorial! how would you make a post request on the client code?

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?

Very nice! Thumbs up! 👍

Great as always 👍👍👍☺

Este tutorial está muito bom Rui, obrigado.

Thank you for sharing....but how the Max distance between the two boards

Can we get it to do two things at the same time like deauth and monitoring ?!

Great video

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?

What about using ESP-Now as well? That is something I watched in another video doing something similar

Thanks alot, can i do it with esp node mcu 32s and arduino mega using wifi module

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 ?

Exelente Video

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? 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!

Bro make more videos on esp32 and audrino ..i am happy i got new channel for this

Would this also work if the esp is mounted somewhere and then it sends data to my laptop via wifi using sockets?

that's possible to streaming wiedo to other ESP32 by wifi? Or exist way, to plug other esp32 by wires?

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?

Good day, I would like to ask, what if my input is CO2 sensor, where do I put my analog pin in the ESP32?

Muitp bom!obrigado pour partilhar.

Thank you

Is possible a nodeMCU as server to two or more nodeMCU as client? Client will use to get status sensors and controll some relay.....

Fantastic tutorial! I was wondering, would it be possible to connect more than 2 devices together and make a sort of little network?

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?

When I have an normal ESP8266 01s, do I have to upload the Code to the ESP or the Arduino?

very good tutorial thx, I've one question , how IP adress was made ? thanks

How fast can you make the GET requests? It will be awesome if we could make "real time" data acquisition

What should be the range between 2 nordmcu for communicate

Can you do this but with an ESP32 CAM and ESP32 connected to a TFT display?

great porject gj

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?

Sir, can we establish communication between two different versions of esp8266 through HTTP??

Excuse me, is there any way to change the lcd with ST7789 led?

@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

Rui será que é possível fazer um server para dois clientes ? Muda alguma coisa no código ou segue esse caminho

What is the preferable and maximum distance between the two esp?

is it possible to do this between esp32 cam and esp8266? if so, please help me how to do it. tnx for your help.

is'it pôssible to have a mqtt server on the esp32 access point and the esp32 client connect to mqtt server to publish and subscribe

what is the max range you could get out of communication ?

Nice

Hi, nice tutorial. What is range of this comm, if its couple of meter isnt then better to use BT? Thanks for sharing.

How multiple Temperature received the receiver and show TFT display???

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!

Can 1 Esp32 be connected more than one esp32 for example, one esp32 connected to 6 esp32?

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 you help me on how to press one button on esp32 so that another esp32 light will turn on? Please.

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

Boas. Parabéns pelos videos de qualidade Rui. Qual é o alcance de comunicação? Obrigado

Can I send bme data to nextion display

very nice

Excuse me you can make that 8266 as server and client at the same time , thank you

master can would u make a tutorial about esp32cam telegram bot

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

Is it possible to do it for esp8266 ?

Somebody knows how to connect a router with this project? To alarge the connection. If you know please tell me

Nice video! Great demonstration of ESP32 access point capabilities, and spin up http server on them as well. I love Esp32 and I'm making some videos on my channel about this and similar topics. You should check it out guys.

...How to send decoded gps Neo-6m (stratum1) data from AP to multiple esp client (stratum2) with FC_16 ledmatrix display in other area of the house?.. synching Hours: Minutes:Seconds ,date,..etc.. basically the internet (gps data) comes from the satelite...as an alternative to NTP

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?

Abo get ! 👍🙋🏼‍♂️

How to Replace BME280 TO AMT1001 Temperature Sensor.and what code.

Perhaps you may have a look at the proprietary so calls "802.11 LR" WiFi feature of the ESP32 that supports long range data transmission up to 1 km! "LR" stands for long range some joking and say it means low rate because it is slower than nomal Wifi. This (routerless) setup in the tutorial would be an excelent usecase for this properitary feature because is can not be mixed up with normal WiFi standards. See www.hackster.io/news/long-range-wifi-for-the-esp32-9429ab89f450 > The 802.11 LR mode is a patented custom mode that can achieve a 1 km line of sight range so long as both the station and the soft-AP are connected to an ESP32 device.

How to send or receive digital data

Hello Rui i am happy to subscribe your channel can you share video esp32 to esp32 led and servo motor control between two esp32 board (with out external router) thanks
