I have the LidarLite on my quad with a Pixhawk controller running software version 3.2 and I see the ranging values in the setup screen. When the quad is sitting on the ground on the landing gear, the LidarLite is about 50cm above the ground. Does anyone know if there is a place to set the offset so that the Pixhawk realizes that when the range is about 50cm that it is on the ground? Or is this automatically calibrated?
By the way, the measurement from the LidarLite is amazingly accurate. The ranges given by the LidarLite vary about 5cm from the actual measured value with a ruler.

I am trying to set up a LidarLite sensor from PulsedLight - and have a question, maybe you can help;
I set it up according to the wiki (new sensor, manufactured Feb 2015, interfaced with a Pixhawk via I2C)
http://copter.ardupilot.com/wiki/common-optional-hardware/common-ra...
In the wiki it points to the Flight Data Screen of the Mission Planner to test the sensor,
but I only get zero as reading in this window.
But if I check in the terminal,
I can see that the sensor is working (see attached file),
so is it working ok? Is the wiki wrong?
Thanks a lot,
Felix

So this is where it is a little tricky. I use both the APM Planner 2 and the old Mission Planner for configuration. I started with APM Planner 2, which has the configuration setup for the Lidar Lite, and then after configuring some of the newer features there, switched back to the original Mission Planner because it's regular features are more stable.
In the old mission planner the values look like the following:
The screenshot in the original message is from the APM Planner2.
