Hi,I have an LSM6DS3 connected to an ESP32. I can see the INT1_INACT_STATE and INT1_WU interrupts attached to INT1 coming through, and I can read WU_IA and SLEEP_STATE_IA in WAKE_UP_SRC after the interrupts.However, the SLEEP_STATE_IA interrupt comes...

I have Pololu breakout containing a LSM6DS33 connected to a ESP32 module via I2C. INT1 is connected to GPIO15. I am driving Activity and Wake Up to INT1. The ESP32 picks up the interrupts reliably. I would like to know whether the LSM6DS33 is active ...

Regarding this matter, I can report the following additional elements:I differentiate between a SLEEP_STATE_IA event that means the device has gone to sleep (vs a SLEEP_STATE_IA event that means the device has become active again) by looking at the t...

Yes, the other thread relates to the same application. I have further comment on the matter, but it might be better to do that on that thread.

Hi Eleon,I had kind of abandoned this thread after updating the question... I did not investigate the matter further after moving the myIMU.readRegister(&wkSrc, LSM6DS3_ACC_GYRO_WAKE_UP_SRC); step to the loop() function. This worked fine.So, I don't ...

Hi Eleon,Thanks for the reply! As I understand it, the SLEEP_STATE_IA bit is not capable of being latched; only the WU_IA state bit can be latched. Either way, I already detect SLEEP_STATE_IA from the interrupt within an ODR cycle.The bigger problem ...

To add to this question, I have fixed the problem by moving the reading of the register out of the ISR.
