I2C communication between 2 Arduinos with updated wire library
The problem I see is the Arduino 101 uses an Intel microprocessor (Curie) instead of an Atmel microprocessor.

The only information I could find is on the Arduino page for the 101, which mentions it has dedicated pins for I2C, but it also says that you can use the Wire library. Maybe you just need to update your IDE?

I'd help more, but I can't seem to find any useful information on the Curie...
