What about the power consumption? ESP32 is not the best in term of energy efficiency, I guess that a series of crypto operations like the ones requested by a WG tunnel would have an impact on power and this can be a problem for a battery-powered ESP32.
- flaviut 4y agoWiFi is just not really well suited for battery use. They're really power hungry. It's usually nRF52 series in use there. Maybe the ESP32s with Thread or Bluetooth LE, although I'm not familiar with that.
- nirav72 4y agoDepends on your use case/application - for sensors, most people use deep sleep, so the module wakes up after some interval, takes a reading and then either does a http post to a service or sends off MQTT message and then goes back into sleep mode.
