~ rostopic echo /scan //can not grabScan data ,
angle_increment: 3.39666002113e-19

is it ok on windows SDK ?

from rplidar_ros.

With latest github revision my rpLidar A1 doesn't get any data back either.
Checking out an older revision makes it work:
git checkout c67b213
catkin_make

Also, why can't we update firmware to 1.24 for rpLidar A1?

from rplidar_ros.

@kintzhao frame_grabber can grab Scan data on windows.
