Description：

Report data information, the reporting interval can be set to 60ms~1s, the default is 60ms, the threshold

analysis of each word is as follows：

Length: the number of bytes except the frame header and check byte, 0x0A, fixed byte

Address: 0xD3, fixed byte

Distance: Unit: cm, occupies 2 bytes, high order first

Reserved: 1 byte, value 0x00, fixed byte

Status: Target presence or absence. Occupies 1 byte, 0: No one 1: Someone

Signal strength: unit: k, occupies 2 bytes, high order first

Fretting: value 0 or 1, 0: no fretting, 1: with fretting

Radar off: Whether the radar is off, the value is 0 or 1, 0: not off 1: off

Check: Sum check, all bytes except check word threshold are sum, and the lower 8 bits are taken,

occupying 1 byte

eg：
