I'm having an issue where upon entering deep-sleep the ulp timer cannot wake-up the main processor despite the algorithm working before adding the RainMaker components to the code. Has anyone had this issue or other similar issues when combining these 2 components of ESP? Any advice would be...
The XIAO ESP32C6 has a complete deep sleep mode and wake-up function. Here we will show two of the more common examples offered by the ESP. Demo1: Deep Sleep with External Wake Up This code displays how to use deep sleep with an external trigger as a wake up source and how to...
In this tutorial, we will learn about ESP32 deep sleep modes and wake up sources using ESP-IDF. We will show you how to put the ESP32 development board into deep sleep mode. Furthermore, we will also discuss different wake up sources through which ESP32 can go from sleep to normal exe...
