Is the ESP32 will going to support a MESH function like ESP8266-MESH?

ESP8266-MESH function is better than ESP-NOW function according the PDF from ESPRESSIF.

And now, ESP32 only support to ESP-NOW, not MESH function like ESP8266-MESH.

We think that the MESH function can use to be a main network of smart-home application.

My question is: Will the MESH function going to include at ESP-IDF?

It's not necessarily 'better'; mesh software just serves a different purpose than peer-to-peer broadcasting functionality like ESP-Now. With that being said, we are working on mesh networking on the ESP32, however we still need to get some kinks out before we publish it. I expect the first release of the software to be somewhere in the first quarter of this year.

When I read about ESP-NOW I had a very good feeling. I wanted a whole range of Smart Home applications designed around ESP32, and NOW has the functionalities to beat ZigBee in shorter range... at least what I figured.

task_t coffeeTask()
{
	while(atWork){
		if(!xStreamBufferIsEmpty(mug)){
			coffeeDrink(mug);
		} else {
			xTaskCreate(sBrew, "brew", 9000, &mug, 1, NULL);
			xSemaphoreTake(sCoffeeRdy, portMAX_DELAY);
		}
	}
	vTaskDelete(NULL);
}

Ah, sure, ESP_NOW is most definitely useful, I use it in some applications myself. It is, however, just a way to send arbitrary frames to whomever may be interested, not a mesh tool by itself: a mesh implies routing, store&forward, retransmitting lost messages etc, and ESP-NOW, by itself, does not do this.

Like everything in telecomunication, the protocols are just code, running on a chip to do the stuff you need it to do... so if you have a way to listen to waves in the air, and possibly send a response, than it's just a matter of programming the protocolls you need to achieve your goals. MESH is just... firmware ;)

(Like you can implement IP protocol through morse code :D Since you only need to define the way you interpret those perky 1-s and 0-s, the guy clicking them out with it's fingers doesn't need to know what they are for :mrgreen: )

Code: Select all

task_t coffeeTask()
{
	while(atWork){
		if(!xStreamBufferIsEmpty(mug)){
			coffeeDrink(mug);
		} else {
			xTaskCreate(sBrew, "brew", 9000, &mug, 1, NULL);
			xSemaphoreTake(sCoffeeRdy, portMAX_DELAY);
		}
	}
	vTaskDelete(NULL);
}
