How to connect 2 or 3 lidars to Pixhawk board

I am trying to connect 2 lidars sensor to pixhwk, lidar 360( for looking around) and TFmini Lidar (for looking down), but Pixhawk always reading one at the time.
I connected PRlidar A3 into Serial 1 and TFmini Lidar into Serial 2.
both working fine when they are connected separately.
Has anyone have experience for connecting two lidars at the same time into pixhawk board?

I solved it,
the problem was on RNGFND setting

here is video of lidars working

How did u do the connection?
