Hello,
I get an error message when running this function:
int ret = i2c_reg_write_byte(data->dev, cfg->i2c_addr,
LSM6DSOX_INT1_CTRL, test);
I know 0x0BAE0002 error means NRFX_ERROR_DRV_TWI_ERR_DNACK but hard to tell what is the cause of this error.
If I run the sensor in polling mode, everything works fine which can exclude error because of wiring.
Any help on this will be helpful.
Here is the error message.
