Interested in ESP32 Audio: ukposts.info/slow/PL5vDt5AALlRfGVUv2x7riDMIOX34udtKD Looking for all my ESP32 projects: ukposts.info/slow/PL5vDt5AALlRdN2KyL30l8j7kLCxhDUrNw

Thanks for taking the time out to show your experiment, workings and results :-) I love how you balance a journey from nothing to context to straight-to-the-point... makes it easy to skip over what I thought I knew, then realise you know more than me, becasue I can go back and listen more carefully. Cheers!

Easy and concise examples and Demo of the ESP Now functionality. Cheers!!!

Thank you for sharing! Great job!

Amazing video, first one on ESPnow that went though the code like this instead of saying "Okay now copy and paste this code".. Great video, Subbed

Nice Thanks 4 showing this , its epic love to try it :D

Thank you very much. I was (and still am) struggling to find proper documentation for this, but your example was extremely clear and lucid. Thanks!

This is really helpful, thank you

Great video, as always!

Great video, thank you. I'd really like to see one explaining how to send data such as A0 pin or BMP280 to another display and have that display on a oled screen... Keep up the great work and thanks for the guide 👍

good example thank you

Thanks for clear to the point tutorial. I found the button doesn't always toggle the led in the 'other' ESP32 dev kit module, like about 1 out of 3 times it will miss even when modules a 4" appart, but serial monitor records success. I have heard that delay() func. can block ESPNow receive is this an issue or not in this case?

Very clear and useful. Thank you. If I may, it could have been better if you had two ways communication, such as slave responds with data to the master.

This was a fun video and I was able to make the changes as shown and flash a NodeMCU board as a slave. Out of curiosity I attempted the multi-master in the same way..... which lead to a giant rabbit hole! I was able to add lots of libraries until the wifi types started clashing with SDK libraries. I guess the 8266 implementation just isn't as good.

Great example thanks

Thanks for the explanation, I wonder how much bandwidth this method can have. Could you perhaps do an experiment in future videos?

great stuff. i'm guessing that the device has to be awake when that register peer logic is called. can the code just dynamically try to register the peer before every message if it wasn't found at init?

Thanks for the good video. Comments: 1) ESPnow is working well for ESP32 as well. 2) Instead of sending strings you can send a package of variables (structure) , for example few integers. So easy to refer to a specific variable. 3) I am not sure I understand the protocol of one to many" if the MAC is FFFF*, so all ESPs in range get the message? I would think it is required to add the specific MAC addresses of the target devices.

Thanks for sharing about esp now. I need this for my project and was looking at hardware change for Zigbee and now I don’t need to.

Thank you.

This has been a great video for helping me get started with ESP-NOW! Thanks for the terrific example! One question; I realize that ESP-NOW is using standard Wifi channels but how do you select the channel that will be used? I can't find any reference to a channel in you example so I assume it's defaulting to a specific one?

what program do you use in the video? thank's

Nice explanation. By the way, what editor/IDE are you using?

Informative video. You can take a look at PJON, it abstracts the ESPNow making it easier to implement. It has this auto register feature which allows you to add nodes on the fly as well as encryption setup.

Great video. I've got it all working but can not work out how to send just an (int). Please can you help.

How can 1 use the ESP 32 board and a rf radio pair to communicate with other station with same setup? via serial console when connecting to a pc? can you make a tut on this?

Interesting, could be such packages received/sended by non-EPS32 devices, for example, by normal Linux PC with "normal" WiFi card?

Great!

This is using an variant of wifi broadcast for broadcasting right?

You have no idea how helpful your video was! Despite digging through so many libraries and reddit posts, your video helped clarify so many missing pieces. I have a comment and a question: I hope this comment helps others, but my experience in using and ESP8266 was the eep-now.h library does not work with esp8266 boards. The arduino IDE would only NOT throw an error when was chosen as the library. If you then read through that library on GitHub, you'll notice the espnow lib has far fewer options. I don't know if there is a workaround, but it seems the more roboust esp-now lib is only compatible with esp-32 boards. My question is: I like how this is one file for both boards. However, if I had a button on pin 4 and an LED on pin 4, how could I differentiate between them in the code? My pseudo-code in my head has me thinking adding to the if statement: if (macAddr = board1) && (digitalRead(button1) == LOW) digitalWrite(led1) on board 2. But that's where my thought falls short. How could I nest an if statement to toggle the LED on another mac address? Thanks again for your help!

If I am interested in repeating what you did, what will I need to purchase and DL?

Since it doesn’t have to associate with a WiFi access point, it should be much faster to send a message for a device that mostly sleeps, wakes up, and sends out some data before going back to sleep.

I'm guessing you can't do ESPNOW and wifi (in AP or STA mode) at the same time? So if you wanted to create a system where 2 boards were to detect each other, you'd need them to time slice between wifi and and ESPNOW both "pinging" the broadcast address to alert any other ESPNOW devices of their presence/identity?

Can you post Arduino code instead of platformio?

how can we put a basic keyboard on this chip please?

I need to have 4-6 ESP32 Cams. I need to tell them all to 'get frame buffer' then one by one send their frame buffers wirelessly to a pc. ESP Now seems like a good choice for the communication part but what method would be best for sending all the frame buffers? Framerate doesn't matter. I just need the data but obviously the quicker the better.

Just wondering, does ESP Now work between the ESP32 and ESP8266 modules?

I found them easy to set up. But the info on rate and bytes is not equal... For ESP now, it's 250 byte (14 word) I believe it's UDP transfer? But docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/network/esp_now.html Says it's slightly different. And I also hear.the max rate was 2mb. I ran a 'quick test on range' and found they were pretty good, local low power was on par with 2.4ghz WiFi.. as in a normal AP.

Is ESP-NOW only available on ESP32 or on any ESP8266 Devices ?

when i tried practical communication of two esp boards using espnow i get only 15-20metre maximum range not a completely open area ,almost 2-3 walls were there between the two boards. I still dont understand how people claim to have range of above 200metres oin blogs and videos .Do you experience the same atomic 14?

Can you show me the display codes ? Thank you !

i cant believe that someoone is using vscode with the arduino ide theme. crazy people from the the internet! anyway, nice video.

Could you not use this to make an auto discovery? Have the master broadcast its mac, then all the peers respond with their MAC's and it would then save those and use them in later instead of broadcasting.

where to download esp_now library

Please come ESP32 SIM800L videos master :)

Thanks for sharing, Do you happen to know how to do it using Micropython? Thanks in advance for your help Daniel

Does this code work equally well for the new ESP32-S2?

Are they hooked up to a usb hub?

Does a distance matter?

1000 LIKES

Great video, thanks. I'n my recen investigation I've found that ESP8266 stops receiving broadcast esp-now messages if you do a WiFi network scan. github.com/espressif/ESP8266_NONOS_SDK/issues/334 May you confirm that in your setup?

They're using 802.11 frames so I don't know why they imposed a 250 BYTE packet size. I don't see any reason they don't just adopt the normal 1500 BYTE packet.

nice good can i control more led and servo motor like this please share come i want to try thanks i am happy to subscribe your channel

Why do you feel the need to annoy the hell out of people with totally irrelevant music?
