VL53L0X: Possible to change I2C address permanently?

Hi everybody!

Just a short question about the VL53L0X Time-of-Flight ranging and gesture detection sensor.

The datasheet mentions a 'Programmable I2C address'.

Is it possible to change the default I2C address to another address permanently?

Will the new I2C address be stored in the VL53L0X permanently?

I mean if i run the VL53L0X through a complete power cycle:

- VL53L0X on... set the new I2C address

- VL53L0X off

- VL53L0X on... Will the new I2C address still be available?

Best regards

Tobi

Unfortunately No, you cannot.

The issue is there is no user-writable data location that will survive a power cycle.

The only way is to change the address after the power cycle.

Hey John! Thanks for the answer... even if the answer is quite disappointing for me.

I thought it would be easy to create a sensor array on the I2C bus and i did choose this sensor because of this feature.
