i2c scanner on GY-80 sensor only finds one address

Official Hardware Retired 101

I tried to scan i2c address of 10dof sensor GY-80 using i2c scanner code from here Arduino Playground - I2cScanner

GY-80 consists of 4 sensors and should have 4 i2c address. When I tried the code using Arduino Uno, it confirms that it has 4 addresses, but on Arduino 101 it found 1 address only.

Why does it only find 1 address in 101 while Uno can find 4 i2c addresses?
What did i do wrong?

The forum I2C scanner does not work with the curie. Check this post out for the one our moderator changed. OLED Library - Arduino 101 - Arduino Forum. Believe that there may also be an example for the wire library bus_scan.ino.

Thanks Mike, that explain why I couldn't even get I2C address of an LCD using 101. Do you know when the new firmware will be available that correct this i2c problem?

by the way, I did use the modified i2c_scanner you mentioned. Now, it gets 2 i2c addresses. Two i2c addresses still missing.

But thanks anyway. I now know what the problem is.
