Arduplane 3.7.1 issue with lidar in serial and I2C port

ArduPlane Plane 3.7

Light ware range finder doesn’t connect with serial as well as I2C port .

It’s shows bad lidar health.

What could be the problem.

Which LightWare rangefinder are you using?

Do you get any sonarange results at all even though ‘bad lidar health’ is being shown?

I am using sf11/C range finder .

Now it’s working with telemetry 2 port

Thank you .
