BQ76942: BQ76942 arduino interface

Part Number: BQ76942

Tool/software:

I am working on an Arduino based data logger as I2C interface with BQ76942. 

I have written a basic code to check out the cell voltages. But the problem is, I am getting the correct voltages every 6-7 readings. Am I missing something?

Also as per the datasheet, the write and read addresses are 0x10 and 0x11 respectively but as per the port scanner response I am getting 0x07 and 0x08 respectively.
