Microprocessors and Microcontrollers - Question and answers

I'm working on a battery-powered IoT project using an ESP32 microcontroller, and I'm having trouble with the deep sleep mode. The device wakes up prematurely or not at all. Can someone help me troubleshoot this?

Microprocessors and Microcontrollers troubleshooting power-management

I've set up the ESP32 to enter deep sleep using the RTC timer for wake-up, but sometimes it wakes up after just a few seconds instead of the configured 10 minutes. I've double-checked the wiring and power supply, and I'm using the Arduino IDE with the ESP32 board manager. I've also tried adding delays before sleep, but that didn't fix it. What specific steps should I take to debug this issue?
