An attempt to write an interface to the fitness tracker "Max Buzz" that I was given as part of the Virgin Pulse Global Challenge.
This is just for fun, to see how far I can get and to learn something along the way.
The "Max Buzz" is a BLE (Bluetooth Low Energy) device and is compatible with the Generic Attribute Profile (GATT). Therefore some information is easy to retrieve by using one of the various Bluetooth explorer tools (I've had good success with the LightBlue® Explorer app for Android).

Service 0000a520
Characteristic 0000a523 ro Returns the same two bytes as 0000fcc8 at the end.I'm working with linux, but tools like gatttool consistently failed to connect to the device, so I couldn't get any information about services & attributes. So right now I'm handcrafting bluetooth packets according to bluetooth packet logs from my android phone.
