Two way🙂
You're mic and camera qualities are so good. It makes the video so interesting
Very well put together video. Thanks for the clear example.
Best IOT tutorial channel on youtube..😍
great video ,thank you for sharing
Cool, l was looking for that! Top man , thank you
thanks for the great explanation sir
thanks for always sharing
Thank you for your very helpful and interesting video. I have subscribed and look forward to more videos :-)
Here is the next part of ESPNOW, Two way communication- th-cam.com/video/3mNawOV1W9k/w-d-xo.html
@@techiesms ah brilliant, thank you very much, just watched!
Great video Thanks! 👍😊
Hi. I am interested in all 4. Especially the 4th "ESPNOW to internet(Blynk)" Thanks for a to the point video. Great job!
Magic, magic 👏👏
Excellent brother.
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?
9:58 wow that was a hot day (48C) at such a low humidity relative (27)! It would be useful to see ESPNOW central receiver to also able to connect to WiFi (as well as ESPNOW) or perhaps a serial link to another ESP module for the WiFi. I like the way you cover a lot of ground quickly just giving the relevant info - thanks.
Great video sir!
Glad you liked it!
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 😊
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??
I love your videos. Please make a video on ESNOW_LR (Long Range protocol) for extra long range.
It seems perfect to activate an alarm inside my house in response to winding sensors in doors and windows. Greetings
perfect application
I have tried esp now protocol, slave sending sensor data to master.
Surprisingly, i got about 500m range and the data comms still pretty good.
Woah….
500m
Which ESP BOARD u have used ?
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.
great work sir. one suggestion- pls improve background
Hello Sachin, do we have a way to make ESP-NOW Mesh? Just like a WIFI-MESH?
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.
Can we use this as a intercom device for rider in two way communication.
Besides the builtin serial terminal you used. What is the other terminal you used that was displaying data in yellow? Love your videos. Keep up the good work.
The other terminal is realterm
Exactly
Great replacement for rf remotes
🆒 Excellent video! Thanks from whole 🇵🇰
What will happen when it already consumed 250 bytes of data limit?
awesome!!!
Thanks
Do watch out the next part of the video,
Two way communication- th-cam.com/video/3mNawOV1W9k/w-d-xo.html
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.
I’ll also upload video for that. Stay tuned…
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.
Here is the video that will guide you with using ESPNOW on esp8266
th-cam.com/video/3mNawOV1W9k/w-d-xo.html
Grazie, siii. Lo avevo appena visto ieri. Sei un grande!!.💪
Dear sir
Our project is based on Ai,iotE3sp32,based carbon monitoring system please suggest pcb, device used in our project
How many devices support this protocol in one connection
I don't have ESP32, so I can use a ESP8266/NodeMCU as Master and Wemos D1R1 as a Slave under ESPNOW ?
plz make a espnow weather station with outdoor sensors
Very inspiring video sir. I am a big fan of you. I have a project idea. I want to collect sensor data from 5 "slave" nodes and want to show those data sequentially on "master" node. Is it possible ? If possible, then guide me.
Yes
It will use many to one configuration in ESPNOW protocol
Hi. Can you make a project on controlling a robot car with fpv camera using espnow? Thks
nice, great video, thank you, possible used es8266?
Yes, of course
Hi , I want to communicate two esp32 c3 via bluetooth using VS code . And check the range. Which prgrm should I use?
It would be great project to start with; if we can integrate ESP-now with Arduino IOT cloud and control/get data from multiple rooms/sensors via master ESP connected to IOT cloud.
We can do that as well, still I haven’t try that yet
How about ESP-NOW LR mode? Can you show us how to do it?
What is the maximum number of devices that can be controlled by a single board?
Also what is the maximum number of devices that can be in the mesh network?
20 devices unencrypted, 10 if encrypted.
@@digihz_data Thank you. Also what is the total number of nodes that can be in the network?
@@ronakranka3317 i don't know about that. But I think it would be possible with more than 10/20 with careful planing of each device.
Is it possible to display various sensor data from different esp32 boards on one arduino IoT or blynk dashboard designed as one device, or integrating lets say 2 esp devices data on a single platform or dashboard?
Yes. I have done it using the ‘new’ Blynk app.
I found an error in transmitter code change (myData - data) so that we are transferring same data variable
what's the camera that you're using to shoot these awesome videos?
Canon 750d
And
iPhone 11 Pro
Is it possible to connect one of those master or slave controller to blynk cloud by connecting with internet
Yes
I mean I haven’t try that, but I think we can make this possible somehow
@@techiesms please make a video on this. It will help us a lot. Thanks
Set power level to maximum 19.5 dbm and check out range!
You can try Arduino MKR NB 1500
I had a small doubt I will be sending data of my gas sensor to esp32 the issue that I am facing is power management, can you make video how to choose power supply for wsn with power hungery parts please
which gas sensor you are using?
@@techiesms MQ-4
I have copy the relay status of master side esp8266 pin to slave side esp8266 pin connected via both same wifi ssid...how should I proceed
Watch this video to know how to use it with esp8266 as well th-cam.com/video/3mNawOV1W9k/w-d-xo.html
Do we control devices with internet too when we are outside home
Not directly with this configuration. We need to do something different to do that, but yes we will be able to do it
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.
i wish i could understand the accent. Looks like good content
i found error esp_now.h not available
any help?
Can you stream the video from an esp32 cam board???
I don't think so....
Yes
On local IP protocol only
What means It can work like wifi Environment smart home
It works on machine to machine talk
That means it don’t require WiFi router connectivity
You can make video on ttgo t call
I already made couple of them
what project you want to see on TTGO TCALL?
@@techiesms how to make a voice call. Making a home automation Using wifi Bluetooth and cellular network together
Wat of developing a project use esp now and paper touch screen
What about ESPNOW and TFT touch screen display th-cam.com/video/3mNawOV1W9k/w-d-xo.html
Would it need wifi
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.
Metro PCB gujrat
Welcome sir
I have randomly seen this video.
And I think something is related to me.
But, I didn't understand the use of this chip
Okay, Okay
Can you please give code for esp8266? Yours compile only for esp32
Watch this video to know how to program it in esp8266 board th-cam.com/video/3mNawOV1W9k/w-d-xo.html
Can you sell ttgo t-call on your e-commerce shop
Not now, but definitely in near future.
I’ll update it on my Instagram
@@techiesms ok😒
Can you make video in python language
My board not working Please help me
whats the error?
What language is this guy speaking in???
