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

[@donovannewton9507]

I need a many, say 9, to one, “chess” style timers. Let’s say the master sets a limit of 15 mins, and then starts a 30 second timer to start the 15 minute countdown. Once started each of the many Nodes would report back the status of what the Node is. Each Node has 2 buttons, Red and Blue. Once a coloured button is pressed, it would highlight the colour pressed at the Node via a light. It would then send this changed state back to the Master. If the opposite colour was pressed it would report this change. At the end of the 15 mins, each Node would have sent the master the time that either colour in the 15 mins was pressed, and how long it stayed that colour during that 15 mins. As an example Node A would report Blue 5:35, and Red 8:25, neutral would be 1:00. Node B might be Red 14:30… etc. Each Node could be 100-400m apart, with the Master not being central. Master would have the ability to reset the system to a ready state once the 15 mins was finished. My guess is sending the status of the Node Red, Blue or Neutral could be sent every 1 second and it wouldn’t need to be perfect. The data on the status would surely be less than 250kb

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.

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?

[@ronakranka3317]

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?

[@digihz_data]

20 devices unencrypted, 10 if encrypted.

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

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

[@rodneytapit5636]

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.

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

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.
