Firmata + Arduino 101

I am trying to use my Arduino 101 in conjunction w/ Maxuino, so i can send the IMU data to MAX. I've uploaded Firmata (v2.5.6) to the Arduino, but the Firmata Test App ( does not seem to recognize data from the board (works for an UNO). Any suggestions?

I had a similiar problem with Arduino M0 Pro. Did you check Boards.h file to see if your Arduino is supported by Firmata?

My code also works with UNO and Mega but not with M0 Pro.

I am able to select "Arduino/Genuino 101" as the board via the tools/menu, and I am able to load sketches. The Firmata sketch appears to load, but the test app doesn't seem to recognize it?
