bno055 not detected via i2c

Hi, 

I am connecting bno055 shuttle board ( with application board) with Arduino via i2c  but running the program (read_all_data or raw_data) which is provided by Arduino gives problem detecting message  ("Ooops, no BNO055 detected ... Check your wiring or I2C ADDR!").

Also when i run i2c scanner program I see an address of  (0x47)  71 which  should be 0x28 or 0x29 if I'm right. How can i solve this?

Thank you.
