YDLidar X2: Error, cannot retrieve YDLidar health code: ffffffff when running python examples

[thehamzan6]

If I run ./ydlidar-test, it works fine. However, running with python, it does not work.

I receive the following error:

python/examples $ python3 test.py 
YDLidar SDK initializing
YDLidar SDK has been initialized
[YDLIDAR]:SDK Version: 1.0.3
LiDAR successfully connected
Error, cannot retrieve YDLidar health code: ffffffff
get Device Information Error
[CYdLidar::initialize] Error initializing YDLIDAR check status under [/dev/ttyUSB0] and [230400].

I fixed the problem.

Under the python code, since the Lidar X2 is one-way communication, I have to set the following line:

laser.setlidaropt(ydlidar.LidarPropSingleChannel, False);

To

laser.setlidaropt(ydlidar.LidarPropSingleChannel, True);

$ python3 test.py

LiDAR init success!

[CYdLidar] Failed to turn on the Lidar, because the lidar is [No error].

I am receiving this error now. How odd. Anyone has any idea?

Changing the baud_rate to:

laser.setlidaropt(ydlidar.LidarPropSerialBaudrate, 230400);

to

laser.setlidaropt(ydlidar.LidarPropSerialBaudrate, 115200);

Fixed the error.
