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 😊
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.
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?
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?
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.
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.
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.
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.
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.
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.
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??
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.
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
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?
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])
