It looks like you need to port the arduino code here:
https://github.com/google/science-journal-arduino/blob/master/src/arduino101/science-journal-arduino.cpp
You should be able to take a puck.js sample, and change the service Id's like you have identified.
As luck has it, I do have an Arduino 101 in my lab to test this further.
