kUserCalSampCount (frame ID 17)
This frame is sent from the module after taking a calibration sample point. The payload contains the
sample count with the range of 1 to 50
Sample count
UInt32
Payload
kUserCalScore (frame ID 18)
This frame's payload contains the calibration score, which is a series of Float32 values: stdDevErr,
xCoverage, yCoverage, zCoverage, magBearth, magHI.
stdDevErr xCoverage yCoverage zCoverage magBearth
Float32 Float32 Float32 Float32 Float32
magHI
Float32
Payload
StdDevErr : The compass samples magnetic field standard deviation error.
XCoverage : Percentage of how much of the X magnetometer axis was covered by the sampling.
YCoverage : Percentage of how much of the Y magnetometer axis was covered by the sampling.
ZCoverage : Percentage of how much of the Z magnetometer axis was covered by the sampling.
MagBearth : The calculated Earth's magnetic field magnitude from the calibration samples.
MagHI : Reserved value; always 0.
kSetConfigDone (frame ID 19)
This frame is the response to kSetConfig frame. The frame has no payload.
