Hi Dirk,
It was mistake, it should be: RP6Examples_20120725f \ RP6BASE_EXAMPLES \ RP 6Base_I2CMaster_03 \ RP6Base_I2CMaster_03.hex
Actually, I have tried this....Sorry...

I am trying this now-
#define SRF_ADR 0xE6
... to ...
#define SRF_ADR 0xE0

Thanks

Terminal shows the same thing. so, problem remains.
Morning, I will try to use pull up resistors.
Hope, it will work.
