![]() Important: if you don’t connect GPIO16 to the RST pin, the ESP8266 will not wake up. If you don’t know how to upload the script follow this tutorial if you’re using Thonny IDE, or this one if you’re using uP圜raft IDE.Īfter uploading the code, you need to connect GPIO16 (D0) to the RST pin so that the ESP8266 can wake itself up. Uploading the CodeĬopy the code provided to the main.py file and upload it to your ESP8266. One of the easiest ways is using the following function in your code.Īfter 10 seconds, the ESP8266 wakes up and runs the code from the start, similarly of when you press the RESET button. There are slightly different ways to wake up the ESP8266 with a timer after deep sleep. We were able to build a weather station data logger with the ESP8266 using MicroPython that only consumes 7uA when it is in deep sleep mode: Low Power Weather Station Datalogger using ESP8266 and BME280 with MicroPython Timer Wake Up However, you should keep in mind that in an assembled ESP8266 board, it consumes a lot more current. In deep sleep mode, the ESP8266 chip consumes approximately When the ESP8266 is in deep sleep mode, everything is off except the Real Time Clock (RTC), which is how the ESP8266 keeps track of time. Flash/Upload MicroPython Firmware to ESP32 and ESP8266.Install uP圜raft IDE ( Windows, Mac OS X, Linux).Flashing MicroPython Firmware with esptool.py.Installing and getting started with Thonny IDE.We suggest using Thonny IDE or uP圜raft IDE: ![]() You also need an IDE to write and upload the code to your board. To follow this tutorial you need MicroPython firmware flashed in your ESP8266. If you have an ESP32, we recommend reading our MicroPython ESP32 Deep Sleep and Wake Up Sources Guide. This guide shows how to use deep sleep with the ESP8266 and how to wake it up with a timer or external wake up using MicroPython firmware.
