Explanation
Altitude
The altitude bytes can be combined (total 16 bits) to represent the altitude information in centimeters. The
structure would be: 0x[MSB][LSB], where MSB and LSB are each two hex numbers (8 bits).
SNR
The altitud
e reading w
ill be associated with SNR ( normally range from 20 to 50 ) to indicate the quality of
the reflections.
Checksum
The Checksum Byte could be used in the following check code:
if (Vers Alti Alti SNR) & 0xFF == Checksum
is_valid = 1 (check passed)
else
is_valid = 0 (failed)
