GETTING STARTED WITH ESP-NOW

where i can find esp_now.h library?

Great video. Difficult to hear with the music.

Can u provide the link for the required libraries for esp_now.h

Pl. tell us how to include missing libraries into the program!!!!!

When i compile any transmitter or receiver program I get the error "esp_now.h: No such file or directory " No idea how to include esp_now.h in the program pl. help!!!!

Tried to watch this but the background music was so annoying I gave up after 40 seconds.

Impossible to listen with muzak. Why is it there?

Music is too loud and not required.????

Thanks for the video. Could have been better if you showed 2 way communication, and also cleaner video editing. Also - don't you share the code?

heyy do you have the code? i can't find it

Yes PLEASE TURN THE BACKGROUND NOISE OFF .. it's not actually music is it?? and it just distracts from an otherwise great video.
thanks

can you make a computer the master?

so amazing video. It's so very useful. But we can control GPIO of slave by Webserver?

can ESP NOW run with WiFi active? I want to have an esp that acts in slave mode inside the mesh network and sends received data over WiFi to an MQTT server. is this possible? can you use both WiFi mesh and Wifi togheter?

Hello, is there any way, with an android application, to control the master esp32 and that in turn order the slaves?

Didn't even know this existed! Good to know!

Hi!. Your code is full of mistakes. It is completely invalid.

ESPNowMaster:
error: esp_now.h: No such file or directory

compilation terminated.
exit status 1
esp_now.h: No such file or directory
it should be like - espnow.h
and then...
exit status 1
espnow_peer_info_t' does not name a type
what about the library? additional directories?

Good video concerning the content ... but it's hard to follow the video to the end with this annoying background music.

Thank you for the video.
I would like to ask if it is possible to store data from a temperature sensor in a file in the SPIFFS and then send the data to another esp32 using esp-now once they establish a connection. the received file would also be stored in the SPIFFS.

Hey, thanks for the video. How can you make sure, that the Esp receives data only from choosen Esp's? What if somebody else would try to send data to my Esp but without my permission? I haven't found a way to secure my Esp. Even when I change my AP password, Esp's are able to send data to mine...

Very useful video, explains the process well. Keep up the good work!


However, clear instructions are needed for a topic like this and the background music makes it difficult to listen. After all, you're programming a micro-controller that is networking without connecting to the internet, you're not showing us "Top ten cool hacks you can do with just a pen lid".

Hey I was wondering the following: is it possible to have both ESP32's act as both Slave and Master? So both the ESP's would have an IR sensor connected and both would be able to trigger the other ESP.

Thanks for the video,
I'm trying to send two 12 bit analog values they range from 0 to 4095. I want to avoid mapping the values.

Now I have more clarity about the send data function.

The part I'm getting stuck at is u int 8_t will only let me send 0-255 values. This is embedded in the esp header file. Is there a way to change it to int or u int 16_t?

Thanks

Hi, great video! But where do I find the esp_now.h library?
