ESP32 has the ability to take advantage of many energy saving modes, here we will understand how to put the device in deep sleep and hibernation mode but above all we will try to understand the differences.
ESP32 is capable of light sleep and deep sleep power saving modes, here we are going to learn how to put in modem sleep and light sleep mode your device and what mean put in sleep mode.
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.
