ESP-NOW Protocol: Establishing Communication Between Two ESP32 Devices - How to Use It

📹 Description:

In this tutorial, I'll guide you through the process of using the ESP-NOW protocol to establish seamless communication between two ESP32 devices. ESP-NOW is a powerful protocol designed for low-power, peer-to-peer communication, making it ideal for IoT projects and sensor networks.

🤔 What is ESP-NOW?
ESP-NOW is a communication protocol developed by Espressif Systems specifically for ESP8266 and ESP32 microcontrollers. It enables fast and efficient data transmission between devices without the need for a traditional Wi-Fi connection, making it perfect for scenarios where low latency and minimal power consumption are crucial.

Your channel is a hidden gem! So glad that it got recommended to me by YouTube

Makes me want to dive into creating something that would use it, like a weather station maybe. I love your subtle sense of humor. Thanks again for another informative video.

You sure have a talent making UI's look great!

[alkhashtee]

I am so lucky to find you here on YouTube. Appreciate you

[paragliding_fun]

Awesome, your tutorials and content about ESP32 and displays really rock! Keep it up!

[digitald]

Your channel is seriously under-subscribed. Thank you for yet another informative and entertaining video. Cheers!

Great video!!! I plan to use ESP32s and ESP-NOW to "connect" them on some model railroad projects. All the best ...

[heatherryan]

I love your sense of humor, and I actually think that the first example that you made was great. Yeah, some people may say that that it is over-engineered, but I really like it.

tip: to avoid looking for MAC and recompilation for other modules, use fake MAC address instead of built in
tip 2: on_sent() and on_receive() should be very fast commands (so no drawing) to avoid problems - better to set the flag in on_receive() and process it out of this callback function

As usual, awesome video. Thanks for sharing 👍

Wanna' learn a german word: *"Spielkind"*
_...but I seriously ❤the way you present your 🎨and the way you teach us fairly complicated stuff"_ 💯👍

Excellent video, straight and to the point, Subbed.

Thanks again for sharing another great demonstration of the capabilities of these devices! Your GUIs are always inspiring! Your videos always fire my imagination!!

[ivovass]

Yes, great continuation from previous video, combined I believe one can have a simple esp32 device connected with sensors and send the readings to a second one with display. Definitely many possibilities for espnow. Thanks for sharing

i need this coffee cup, too. great content by the way.

Great video !! Love to see a few more espnow examples. For me I want to take canbus info into main esp32 & send it out to 3 or 4 display with guages. Look at adafruit qualia 4" round for main display. Always look forward to your videos.

[jeffschroeder]

Your videos really espress (?) how much fun you are having. I find them very inspiring and have had success with most of your examples that I have tried.

Just started to play with ESP NOW. It's fantastic.

[michaelbishton]

To date, I think your most informative and best presentations have been about demystifying sprites. But you always just showed the results on the screen and then just told people to look at your code. Now that you are explaining things, I suggest that you go back to explaining - and covering in an organized manner - how the display functions work. This would help us understand how to build more dynamic displays for areas like avionics, engines, and automation where we don't have fixed parameters.

Didn’t know about this protocol. Super cool and useful!
