This packet contains angle data and selected sensor data scaled in most cases to a signed
2^16 2’s complement number.
Data involving angular measurements include the factor pi
in the scaling and can be interpreted in either radians or degrees.
Angles: scaled to a range of [-pi,+pi) or [-180 deg to +180 deg).
Angular rates: scaled to range of 3.5* [-pi,+pi) or [-630 deg/sec to +630 deg/sec)
Accelerometers: scaled to a range of [-10,+10) g
Magnetometers: scaled to a range of [-10,+10) Gauss
Temperature: scaled to a range of [-100, +100) °C
