ESPNOW as simple as possible | Getting Started, Range test & much more..

What’s the next thing you want to learn ?
1. One to many
2. Many to One
3. Two way
Or
4. ESPNOW to Internet(Blynk)

Hi i was trying to compile the code you shared, an error messages show myData was not declared in the scope! i have try some ESP code from other also it show other error! most of the esp code don't works to me . isit my setting, library version,............... wrong? Please help me!!!!!! the error message (Compilation error: invalid conversion from 'void (*)(const uint8_t*, const uint8_t*, int)' {aka 'void (*)(const unsigned char*, const unsigned char*, int)'} to 'esp_now_recv_cb_t' {aka 'void (*)(const esp_now_recv_info*, const unsigned char*, int)'} [-fpermissive])

how to get rssi with esp now

Can I pls get the master and slave full program?

Call me stupid... Can we combine ESP Now + Blynk + CallMeBot + WifiManager ????

I found an error in transmitter code change (myData - data) so that we are transferring same data variable

How many devices support this protocol in one connection

Would it need wifi

I like your energy very inspirational,
How to make a mesh-network, where devices can join the network automatically when they’re near and a device can send data to certain device via other devices if their not in direct line 😊

Hi. I am interested in all 4. Especially the 4th "ESPNOW to internet(Blynk)" Thanks for a to the point video. Great job!

Running espnow on esp32 with continuous data transfer heating esp board. Are there any specific requirements to throttle up data sending rate for optimum heating??

Dear techiesms,
your shows are all of great help to my tinkering with micro boards.
I now want to build a series of esp32 boards to place around a large building as control and
alarm system.
Thing is I can't find the esp_now.h code, even espressif does not provide it.
I have found several comparable espnow codes but they are all quite different and not what you used.
Do you have a link or copy?

Set power level to maximum 19.5 dbm and check out range!

i wish i could understand the accent. Looks like good content

Hello Sachin, do we have a way to make ESP-NOW Mesh? Just like a WIFI-MESH?

Cool, l was looking for that! Top man , thank you

I love your videos. Please make a video on ESNOW_LR (Long Range protocol) for extra long range.

How about ESP-NOW LR mode? Can you show us how to do it?

Dear sir

Our project is based on Ai,iotE3sp32,based carbon monitoring system please suggest pcb, device used in our project

Magic, magic 👏👏

Hi , I want to communicate two esp32 c3 via bluetooth using VS code . And check the range. Which prgrm should I use?

i found error esp_now.h not available
any help?

Okay, Okay

Hi really liked your tutorial here. I just have one question as to how can ESP 8266 be used in a mesh to send the data from one end to another with the other ESP being the repeater.
Would really like your help with it as I am stuck with my project where I need to send the signal for more than 200m distance.

Hi, I have the ESP32 link installed in my Arduino IDE preferences and I have the ESP32 working. However I do NOT have the ESP32 Examples lib and therefore I don't have the ESPNow examples. Can you tell me where I can download the ESP32 lib from? BTW, Great video and super explanations.

🆒 Excellent video! Thanks from whole 🇵🇰

Excellent brother.

I don't have ESP32, so I can use a ESP8266/NodeMCU as Master and Wemos D1R1 as a Slave under ESPNOW ?

Hi sir what a great tutorial. Is it possible a ultrasonic sensor is connected to the master board and an haptic motor in the slave board will vibrate if the ultrasonic sensor(in the master) detected an object?

You're mic and camera qualities are so good. It makes the video so interesting

esp_now.h: Np such file or directory Can you help me where i can find it?

Very well put together video. Thanks for the clear example.

Can we use this as a intercom device for rider in two way communication.

I have randomly seen this video.
And I think something is related to me.
But, I didn't understand the use of this chip

thanks for always sharing

what's the camera that you're using to shoot these awesome videos?

thanks for the great explanation sir

What language is this guy speaking in???

great work sir. one suggestion- pls improve background

Hello and congratulations for the tutorial.
I ask you: is it possible to adapt these codes for ESP-8266? I would like to build a remote and the form factor is important to me. Thank you.

awesome!!!

Hi. Can you make a project on controlling a robot car with fpv camera using espnow? Thks

What means It can work like wifi Environment smart home

Please could you recommend a good company in India where I can get my PCB board made from a Gerber file? Thanks in advance. Regards.

You can try Arduino MKR NB 1500

Another great explanation video. Thanks for making .

Can I use esp now along with regular WiFi connection??

For example:-
3 slaves sending data to one master using Esp-Now protocol.

Master device reads all data & send data using mqtt protocol on local home automation server or cloud mqtt Server.

Hi bro. Please make a video on Esp8266 as NAS server accessible in over the world using SSD or HHD not sd card or pen drive.

Wat of developing a project use esp now and paper touch screen
