The host system communicates with RPLIDAR core system via the TTL UART serial

interface. Based on the communication protocol defined in this document, the host

system can retrieve the scan data, the device status, the health information etc. and

manipulate RPLIDAR’s working mode.

Figure 1-1 The Communication Between RPLIDAR and Host System

Please refer to the RPLIDAR datasheet for information about the bottom layer

communication protocol and the electrical level definition of the serial signals used

to communicate with RPLIDAR. The communication protocol based on UART serial

port and the data transmission format will be introduced in this document.

SDK and Demo Program

SLAMTEC provides open-sourced SDK and demo program for customers to

integrate RPLIDAR into their systems quickly. The SDK implements all the

communication stacks, driver logics and related data structures described in this

document

The SDK supports multiple platforms including Windows, Linux, MacOS and even

bare systems without an OS.

Please refer to the SDK manual for details.
