Dear ST team, I am using STM VL53L1X distance sensor, and I have some problems with the VL53L1X satel. While the VL53L1X main part (the big sensor) is working perfectly, the VL53L1X satel stops measuring each time I move it.

Please, do you know if there is a way to solve stability problems with the VL53L1X satel ?

Thank you for your help.

Best wishes

Anne

That satel board and the I2C connection are really touchy.

I'm going to guess that if you have more than 6 or 8 inches of wire, you are going to run into this problem.

Try seperating the wire and twisting it. Or use thicker wire.

The right answer are stronger pull-ups, but that's a lot of work.
