Hi.
It was a matter of choice.
We could also have used websockets.
So, no particular reason.
Regards,
Sara

Thanks for this very clear tutorial, which allowed me to realize a project with 1 receiver and 3 senders (DHT, DallasTemperature sensor and Ultrasonic). Everything works perfectly, except that the “Last reading” remains empty. I tried a lot of things without success. What could explain this error? Thank you for your help.
Bruno

Thanks for this example, which allowed me to make a project with 1 receiver and 3 senders (DHT, DallasTemperature and Ultrasonic sensors). Everything works well, except that the “last reading” are not displayed! Despite many attempts, I don’t understand. What is the mistake I’m making? thanks for your help

Hi
Right it works with a ESP8266 but not with a ESP32. My board is a ESP32 WROOM
What should be the code for a ESP32
Regards
Claude

Hi.
It’s included by default.
Make sure you have the right board selected before trying to compile the code.
Regards,
Sara

I can’t run this example as I can’t find the library ESPNOW. It does appear in the available library list on the Arduino IDE

Hi what a nice project I have the problem Slave is Channel 11 and
the ESP8266 Master Channel 1 when I change the master to
wifi_set_channel(11); then it works. What should I change
I changed it to WiFi.mode(WIFI_MODE_AP);

Only one question?
What about a similar configuration:
one receiver with web server inside
multiple senders with sensors
one (or more) receiver with actuator (aca relay)
It’s possible? How can the receiver (web server) absolve the three job?
