RPLidar A2 not showing data in proximity window

Hello all,

I am working on 360-degree obstacle avoidance in a quadcopter. I connected my lidar to the TELEM1 port of Cube black and followed all the procedures in the actual ardupilot documentation. I am finding trouble in getting the data from RPLidar into the proximity window. I have even tried powering RPLidar first and then Cube and vice versa, still no data. RPLidar’s (Vcc, Motoctrl) is powered with 5V BEC.

These are the parameters i have used to set up the lidar

  • SERIAL1_BAUD = “115”
  • PRX_TYPE = “5”
  • PRX_ORIENT = “0”
  • BRD_SER1_RTSCTS = “0”

even i had this issue,
but couldnt solve it


Same here. RPLidar rotates but no data in proximity viewer. Tried different Baud rates, serial ports still no success.

Even i have similar issue, need help.

Issue resolved
I was using RPLiDAR A2M4 which wasn’t supporting the current ardupilot firmware and mission planner. So I upgraded my lidar to RPLiDAR A2M8 and it worked well.
