Using Smart Prescence Detection Software with SATEL-VL53LB to Nucleo-53L8A1A

[kdwood-LUMC]

I have broken the SATEL-VL53L8 into its small PCB form and have connected it with flying wires (about a foot in length) to the NUCLEO-53L8A1A breakout board. It is wired in the I2C configuration and the J9 connector is also set to I2C.
When I open up the Smart Presence Detection software, I only get a sparce reading of different array values, which I believe are coming from the ToF located on the NUCLEO board and not the SATEL. This looks to me like some sort of comms issue, but I am not sure how to tackle it.

Has anyone experienced this issue and know how to rectify it?

Thanks in advance!

Interesting project! If you’re using the VL53LB for smart presence detection, make sure your software supports dynamic distance thresholds and filtering presence detection needs more tuning than simple ranging. Check that your firmware version matches the sensor model, and use a short buffer (like the last few readings) to avoid false triggers. Share your setup details if you’re still getting unstable results that’ll help pinpoint the issue.
