int TYPE_FRAME_BEGIN
Mark the beginning of a set of additional info frames.
Constant Value: 0 (0x00000000)
int TYPE_FRAME_END
Mark the end of a set of additional info frames.
Constant Value: 1 (0x00000001)
int TYPE_INTERNAL_TEMPERATURE
Internal temperature. Sensor hardware device internal temperature. Payload: floatValues[0]: internal temperature in Celsius.
Constant Value: 65537 (0x00010001)
int TYPE_SAMPLING
Sampling parameter. Describes the raw sample period and estimated jitter of sample time in terms of standard deviation. Payload: floatValues[0]: raw sample period in seconds. floatValues[1]: standard deviation of sampling period.
Constant Value: 65540 (0x00010004)
int TYPE_SENSOR_PLACEMENT
Sensor placement. Describes location and installation angle of the sensor device. Payload: floatValues[0..11]: First 3 rows of homogeneous matrix in row major order that describes the location and orientation of the sensor. Origin of reference will be the mobile device geometric sensor. Reference frame is defined as the same as Android sensor frame.
Constant Value: 65539 (0x00010003)
int TYPE_UNTRACKED_DELAY
Untracked delay. Delays that are introduced by data processing, such as filtering, which is not taken into account by sensor timestamps. Payload: floatValues[0]: delay estimation in seconds floatValues[1]: delay estimation standard deviation
Constant Value: 65536 (0x00010000)
int TYPE_VEC3_CALIBRATION
Vector calibration parameter. Calibration applied to a sensor with 3 elements vector output, such as accelerometer, gyro, etc. Payload: floatValues[0..11]: First 3 rows of a homogeneous matrix in row major order that captures any linear transformation, including rotation, scaling, shear, shift.
Constant Value: 65538 (0x00010002)
float[] floatValues
