Detailed Description
Low Power Management for ESP8266.
- In Modem-sleep mode, ESP8266 will close the Wi-Fi module circuit between the two DTIM Beacon intervals in order to save power
- During Light-sleep, the CPU is suspended and will not respond to the signals and interrupts from the peripheral hardware interfaces. Therefore, ESP8266 needs to be woken up via external GPIO.
- During Deep-sleep the chip will turn off Wi-Fi connectivity and data connection; only the RTC module is still working, responsible for periodic wake-ups. To enable Deep-sleep, you need to connect GPIO16 to the EXT_RSTB pin of ESP8266.
