Characteristics

Step count (UUID 00030001-78fc-48fe-8e23-433b3a1942d0)

The current number of steps represented as a single uint32_t (4 bytes) value.

Raw motion values (UUID 00030002-78fc-48fe-8e23-433b3a1942d0)

The current raw motion values. This is a 3 int16_t array:

  • [0] : X
  • [1] : Y
  • [2] : Z

The three motion values are in units of "binary milli-g", where 1g is represented by a value of 1024.
