ESP-NOW
-
ESP-NOW means that ESP8266 and (?) ESP32 nodes can directly communicate, without having to go through lengthy delays at the gateway after waking from sleep. This means much lower current consumption than before for battery powered ESP nodes.
Anyone here try this out?

Aggressively Low Power with the ESP8266 – 10:18

Answering my own question: yes, esp-now does ALSO work with ESP32.

That's significant because it means the much lower sleep current of the ESP32 (as compared to the ESP8266) can be leveraged.

Are you suggesting a new transport layer for MySensors gateway and nodes?
-
I'm not sure what you're asking.
Put simply: if it turns out that a $1.70 ESP8266 can "do it all" without using much power, then it would be good to know.
-
I was asking if you were suggesting to investigate if it was possible to use the ESP-NOW as a new transport like the NRF24 or RFM69
-
@gohan Yes, I believe that's what I said.

In addition, the ESP8285 allegedly has a deep sleep of 10ua with full memory retention:

That's much better than the ESP8266.

This is very intriguing! Looking forward to following this.
