​Hi,

You may check out the guide made for the VL53L0X AN4846: Using multiple VL53L0X in a single design from ST.COM. The same principle is applicable for the VL53L1X.

Thanks,

Julien

I don't want to disparage an ST document, but that one goes a little far.

Here is what you do:

Attach each sensor's 'shutdown' pin to GPIO's on your host.

At boot, put them all in reset.

Bring them out one at a time.

Use the Address Change I2C command to change the addresses.

Repeat for each chip.

And even though it's not strictly required, consider changing the address for all the sensors - even the last one.

That way if you ever get a glitch and a sensor resets, it will start responding on the initial address.
