Lightware lidar in Pixhawk 2.1 I2C 2 port doesn't work

Am trying to connect Lightware lidar to I2C 2 port in Pixhawk 2.1 to use it as a rangefinder. As per Arducopter 3.5.4 release notes says Lightware range finder are supported on both I2C ports. But there is no response and still Sonar range displays as 0. Is there any other parameter need to be changed?

Can anyone help me on this ?


I recall there was a parameter added called PLND_BUS. I haven’t tried it yet, but I suppose it sets which I2C bus the rangefinder is on for precision landing. I’m not sure if it has any effect on rangefinder use outside of that, though.

PLND_BUS = 1 should use the second I2C port.

Thanks for the reply.
Its working now.
It was found to be a connection issue.
PLND_BUS parameter is removed from AC 3.5.4
