(GPIO16 needs to be tied to RST to wake from deepSleep.) Automatic Reconnect On Wake-Up, is the default. So even before you ... ESP-IDF components ¶ ESP-IDF modules as modular pieces of standalone code might be useful for structuring reusable code or including third party components that aren’t part of ESP-IDF. These components contain either a single CMakeLists.txt file which controls the build process of the component and its integration into the overall project. As well as the esp-idf-template project mentioned in the setup guide, esp-idf comes with some example projects in the examples directory. ... Deep sleep flow. Mar 25, 2019 · Nothing being consumed in Deep Sleep. The next step was to re-enable the code and circuity that actually took the temperature reading. In my original design, I was feeding power to the probe from a 3.3v output on the ESP dev board. Following the circuits others designed, this time around I would power the circuit from the power supply directly. Deep-sleep mode¶ The following code can be used to sleep, wake and check the reset cause: import machine # check if the device woke from a deep sleep if machine . reset_cause () == machine . Temporary disable Deep Sleep via jumper setting. If 30 seconds is too short for you, you can use this method. Disconnect GPIO-16 from RST and connect it to GND. Restart your ESP if neccesary.
