Module Communication

Data

♦ Baud rate: 115200bps;

♦ Single byte transmission format: including 1 start bit, 8 data bits, no check, 1 stop bit, 8bit data is transmitted first in low and then in high;


Protocol

Single ranging command

Note: Send the verification code = byte 3 + byte 4 + byte 5 + byte 6 + byte 7;

Received verification code = byte 1 + byte 2 + byte 3 + byte 4 + byte 5 + byte 6 + byte 7.

Send to the ranging module

byte 1 2 3 4 5 6 7 8
description 0x55 0xAA 0x88 0xFF 0xFF 0xFF 0xFF check code


The ranging module returns

byte 1 2 3 4 5 6 7 8
description 0x55 0xAA Freq status 0xFF DATA_H DATA_L check code


Status=0, continuous measurement fails; DATA_H=0xFF, DATA_L=0xFF; status=1, continuous measurement succeeds; DATA_H=high byte of the measurement result; DATA_L=low byte of the measurement result.

Freq=0x89, 1Hz for ranging; Freq=0xA9, 2Hz for ranging; Freq=0xB9, 5Hz for ranging; Freq=0xF9 for axis calibration mode (the axis status is sent back once after receiving the axis calibration instruction).


Stop measuring

Send to ranging module:

byte 1 2 3 4 5 6 7 8
description 0x55 0xAA 0x8E 0xFF 0xFF 0xFF 0xFF check code


The ranging module returns:

byte 1 2 3 4 5 6 7 8
description 0x55 0xAA 0x8E status 0xFF 0xFF 0xFF check code


Status=0, the continuous measurement is failed to be closed; status=1, the continuous measurement is successful to be closed.

Note: The data is returned in hexadecimal, and all the data results will be output by multiplying the real data by 10;

Example: dist=2000.3m, the output data is 20003, which is converted into hexadecimal as 4E23, that is, Data1=0x4E and Data2=0x23.
