VL53L0X : No ToF sensor laser output.

[davelee123s]

I am using a VL53L0 ToF sensor.
If an interrupt occurs, repeat the measurement using the "VL53L0X_GetRangingMeasurementData" function and the VL53L0X_ClearInterruptMask function.
Normally, it operates, but the sensor outputs data that seems to be looking in the air due to unknown causes such as static electricity.

From the IR camera, there is no light in ToF.
Two functions, VL53L0X_GetRangingMeasurementData and VL53L0X_ClearInterruptMask, do not return errors.

When I initialized the phenomenon after checking it, the sensor operated normally.

I'm wondering if there's any data I can check because the data is similar to what I'm seeing in the air about the above phenomenon.

In summary, the ToF laser light emitting unit does not appear to be operating due to other factors such as static electricity, etc. The light receiving unit operates normally and receives data as if it is looking in the air.

 I wonder if there is a parameter or function that I can check the state of the sensor.

thankyou.

Hi:

As far as I know, usually, we use the camera to check if there is laser light. There are currently no parameters or flags available to determine if the emitting VSCEL is functioning properly. sorry for that.
