ESP32 practical power saving manage WiFi sleep and CPU frequency 23

ESP32 practical power saving: manage WiFi and CPU – 1

The ESP32 is capable to activate the energy saving modes of light sleep and deep sleep, but in many cases we cannot use such a solution, but it is still possible to apply some options to the functional units for reducing energy consumption.
Let’s set the sleep mode, disable the WiFi and scale the frequency to the CPU.
