ESP8266 Light Sleep Mode YouTube
To put the ESP8266 in deep sleep mode, use ESP.deepSleep (uS) and pass as argument sleep time in microseconds. GPIO 16 must be connected to reset (RST) pin so the ESP8266 is able to wake up. To put the ESP8266 in deep sleep mode for an indefinite period of time use ESP.deepSleep (0). The ESP8266 will wake up when the RST pin receives a LOW signal.

Light Sleep with GPIO Wakeup in ESP8266. Ask Question Asked 5 years, 3 months ago. Modified 5 years, 2 months ago. Viewed 8k times 0 I have been attempting to create a light sleep for ESP8266, in which I want to make the system sleep and trigger a wakeup on a GPIO input (Like a button press). The code for it is pretty straight forward.

The sleep code is performed by light_sleep () function. It will only wake up when the GPIO pin is triggered, this will be explained in the next section. When ESP8266 wakes up, it will have 200 ms delay before printing the "Wake up" string in the Serial console, then it will perform the initialisation of WiFi again.
Making the ESP8266 LowPowered With Deep Sleep Deep sleep, Power, Deep
A simple application of light-sleep mode is a Wi-Fi Switch, where the CPU can be idle when not operational but the system is connected to Wi-Fi for receiving commands (Wi-Fi transmission is also disabled). Since the CPU of ESP8266 is suspended in Light-Sleep Mode, it cannot respond to signals and interrupts from internal peripherals.
How to use ESP8266's sleep modes in MicroPython
light sleep: the necessary steps to enter timed sleep are a bit fickle, so read this closely (see esp8266/Arduino#7055 for more details): timer-based light sleep can be between ~10.000 and 0xFFFFFFE = 2^28-1 = 268435454 microseconds (~4 1/2 minutes) for light sleep to be entered successfully: the OS timers need to be cleared/disconnected by.

On the ESP8266, you can only put the node into deep sleep for a duration using sleep_duration, note that on the ESP8266 GPIO16 must be connected to the RST pin so that it will wake up again. On the ESP32, you additionally have the option to wake up on any RTC pin ( GPIO0 , GPIO2 , GPIO4 , GPIO12 , GPIO13 , GPIO14 , GPIO15 , GPIO25 , GPIO26 , GPIO27 , GPIO32 , GPIO39 ).

It is necessary to set a delay after this processing, as the light_sleep () function takes a while to take affect and this is to ensure that the code will not loop back when the ESP8266 is still trying to sleep. Step 4. InitWifi () function. InitiWifi () function is very similar to the InitWifi () function used in the previous post.

Parameters. sleep_time_in_us: sleep time, ESP8266 will wake up automatically when time out. Unit: us. Range: 10000 ~ 268435455 (0xFFFFFFF). If sleep_time_in_us is 0xFFFFFFF, the ESP8266 will sleep till. if wifi_fpm_set_sleep_type is set to be LIGHT_SLEEP_T, ESP8266 can wake up by GPIO.
ESP8266 Deep Sleep and Wake Up Sources using Arduino IDE
To place ESP8266 into the modem sleep mode and later wake from a timer, use the esp module. This MicroPython script puts ESP8266 into the modem sleep mode and blinks an LED, which is connected to the GPIO2, every time ESP8266 wakes because of the timer. import esp. from machine import Pin. from time import sleep.
ESP8266 Deep Sleep with Arduino IDE (NodeMCU) Random Nerd Tutorials
I am not sure, but it seems not to be very well known (missing detailed documentation could be the cause). Even outside of these frameworks mostly deep sleep is the standard topic with ESP8266, there is not much about light sleep. Although these different sleep modes are very often used with Arduinos and ATinys. It is strange.
How to add DEEP SLEEP MODE to ESP8266 ESP01 YouTube
ESP8266 + light sleep. JustaCe July 31, 2023, 10:06am 1. Hi all, I'm solving issue with light sleep on ESP8266 (ESP-01). I want to run some code only each +-30min. Sleep itself working almost correctly, but there is one thing which is wery confusing. To enable sleep there must be delay after wifi_fpm_do_sleep which must be at least +1 longer.
power ESP8266 light sleep can't wake up Arduino Stack Exchange
While in Modem-sleep, the ESP8266 will disable the modem (WiFi) as much as possible. It turns off the modem between DTIM Beacon intervals. This interval is set by your router. Light-Sleep. Light-sleep performs the same function as Modem-sleep, but also turns off the system clock and suspends the CPU. The CPU isn't off; it's just idling. Deep-Sleep

3. Light-sleep 3. Light-sleep 3.1. Features The functioning mode of Light-sleep mode is similar to that of Modem-sleep. The only difference is that during Light-sleep mode, ESP8266 powers off both the clock and the Wi-Fi circuit, and also suspends the internal CPU, which results in even less power consumption than in Modem-sleep mode. 3.2.

I saw many tutorials about using Deep Sleep for saving power and running an esp8266 for weeks on a battery. While deep sleep gets by far the largest power savings, it has a couple quirks: the device isn't responsive to commands sent from the app on wakeup, the sketch is restarted rather than resumed Since i didn't need to run on a battery, but just to produce less heat (a thermometer is.
