ESP32 deep-sleep with LSM6DSOX step-detector: how do you cut false wakes?

I’m building a small wearable logger: ESP32 sleeps most of the time, wakes on LSM6DSOX step-detector, logs, then goes back to sleep. Looking for settings that work in practice:

  • ODR/FS and step-detector config that avoids vibration false wakes

  • INT wiring to an RTC-capable GPIO (pull-up value?), latched vs pulsed INT

  • FIFO vs direct interrupt; simple debounce in firmware

  • Re-init after deep-sleep (soft reset, clear INT, reprogram registers)

  • Typical deep-sleep current numbers with the IMU powered vs fully off

Concrete numbers welcome (thresholds, durations, current, wake frequency). Thanks!
