My only knowledge of the ESP32 is using the Arduino IDE but I am interested in ESP-MESH and ESP-NOW.

ESP-MESH sounds like its not really designed for battery powered devices. Its more like Coordinators and Routers in Zigbee/Zwave. ESP-NOW is for battery powered devices?

Is it possible to run ESP-MESH and ESP-NOW on the same ESP32? As well as connect to a WiFi AP for internet?

Why is there a limitation on ESP-NOW of 20 devices? Is there a way to increase it?

Has anyone done any power calculations on the ESP-NOW protocol? The ideal scenario for me is to post once every 15 minutes or alert based either directly to MQTT (not ideal) or using ESP-NOW to another ESP32 connected to the internet. I will be using 2 AA Lithium batteries.

1. ESP-MESH\ESP-NOW\Connecting Router can be run simultaneously on one ESP32
2. At present, ESP-NOW only supports binding of 20 devices at the time of sending, and receiving data is not limited.
3. The power consumption of ESP-NOW can be found at: ... cteristics
