Hi,I am having an issue with the VL53L1CB TOF sensor where I cannot communicate with the sensor via I2C. I have everything configured correctly as far as I can tell but the API is returning status error -13. I am testing with a L476 nucleo and the SA...

Hi,I am testing a VL53L4CD sensor for a measurement application. I am using the example code from the API to test out the sensor and I'm having an issue with the minimum distance of the sensor. It will not report a measurement range less than 70mm an...

I have been looking at the I2C traces with logic analyzer and noticed some different behavior depending on which mode the device is in. It looks like in autonomous mode when the device is working the delay between the mcu receiving data and replying ...

After some more testing I have some more results. The sensor is working in autonomous mode, and reporting good ranging data in that mode. However, if I try to switch to ranging mode or multizone scanning mode the API reports error -20.

Hi,My coworker was able to work around our issue by using the calibration offset. He set the offset to 70mm then subtracted the same amount from the results data, and this let us measure with the sensor. I would like to fix the issue still, and our t...

A hardware issue was my first though but I haven't been able to find anything yet. The chip is getting power and orientation and VCAP are correct. There's only one VDD pin on this chip, no VDDA. Continuity on the programming lines tests good as well.
