Question

Hello,I´m using VL53L1X sensor using the Api provided, all is working but I have a question:

I use Xshut pin to save energy, Do I have to call VL53L1_DataInit() every time that I pull Xshut to wake up the device or only the first time after my microcontroller reset?

And the same question with VL53L1_StaticInit()

I do not have clear what to do or what not to do every timeI wake up the VL53L1 using Xshut.

I have tested both options and it seems that it is not difference but I want to know the best way to manage the situation.

​Yes, Shutdown really does shutdown everything, so you have to start over and call VL53L1_StaticInit() and VL53L1_DataInit()

But you don't have to use the Shutdown pin. If you Stop() the ranging the chip really does go into a very low power mode barely keeping the memory alive.

It is very low power. Typically only 5 or 6 microAmps.
