Issue with i2C Address Set/XShut Function

[nh1628]

Hello,

I'm trying to get 2 VL53L4CD sensors to work together and have them tied into the same SDA/SCL ports on my ESP32-S3.

I keep getting an error where it reads once (probably when it first loops), but then gives me a i2cWriteReadNonStop returned Error issue. Am I using the with the setI2Caddress feature incorrectly? Or is there an actual bug? Or is it just not turning the device back on?

This is the code that I am using: `/ Includes ------------------------------------------------------------------/

Resolved the issue by setting the addresses from 0x29 and 0x28 to 0x51 and 0x28
