LSM6DSL vs LSM6DSR with (Acc/Gyro) INT1 issue

[AHuta.1]

Hi,

We have a PCB design which used to have LSM6DSL and we were using ACC/GYRO data from the sensor. Since we switched to the new LSM6DSR chip the INT1 does not trigger (when data is ready) anymore even though the sensor should be similar config (if not the same). What could be reason for this? The chip responds with NACK from commands which were used to work on LSM6DSL.

Worth mentioning that INT2 triggers as expected w/o issues, but not INT1.

Regards.

Hi, it turns out, the issue was, INT1 pin was not kept low while doing I2C transactions. After ensuring this (which is a new change from LSM6DSR) the device works as expected. Regards.
