2.3.4 Distance signal strength
Refers to the signal strength, the default output value will be between 0-65535. When the
distance measurement gear is fixed, the farther the distance measurement is, the lower the
signal strength; the lower the target reflectivity, the lower the signal strength. When Strength is
greater than 100 and not equal to 65535, the measured value of Dist is considered credible.
Example :
If payload is: 01D7(H)=471(D), distance signal strength
=471, 471>100,471
≠
65535, the
measured value of Dist is considered credible.
Customers can judge whether they need to adjust the environment based on the signal strength.
2.3.5 Interrupt Pin
This data field shows if this packet is generated by interrupt or not. Click here for the hardware
and software set up.
Example:
0x00: Normal uplink packet.
0x01: Interrupt Uplink Packet.
2.3.6 LiDAR temp
Characterize the internal temperature value of the sensor.
Example :
If payload is: 1C(H) <<24>>24=28(D),LiDAR temp=28
℃
.
If payload is: F2(H) <<24>>24=-14(D),LiDAR temp=-14
℃
.
2.3.7 Message Type
For a normal uplink payload, the message type is always 0x01.
Valid Message Type:
