"@Emin: You can manually control the servo position through the lw20, which makes it easy to point it in the same direction the drone is moving - provided you have a servo that can achieve that range of movement.

"I am unable to find a version of the 3.3.2 software to test, but I can confirm that Heli 3.3.3 works as expected with the Terminal and SF11."
"Hi Thomas,
As a first step, try download the LightWare Terminal application (If you haven't already: http://lightware.co.za/shop2017/content/6-software), and use the 'Drone' option to configure ardupilot for the rangefinder."

"Hi Neal,
I can't confirm if the SF11 will run on the PX4 stack, but from what I can see it might be possible. On this page: http://dev.px4.io/flow_lidar_setup.html they say: "SENS_EN_SF0X Set to 1 to enable lightware distance measurements (e.g.…"

"Thanks for the input Cala. I'd love to hear how your flight goes."
"Hi DG,
To integrate the SF11 with the Pixhawk you only need to wire it up and set some parameters. You can visit http://ardupilot.org/copter/docs/common-lightware-sf10-lidar.html for more info on configuration.
AC 3.4 does have lidar terrain…"

"Hi Jason,
I've been through the MinimOSD config tool and I don't see Sonar Range either, it looks like you will need an alternative OSD or speak to developers who work with MinimOSD.

"Hi Jason,
The SF11 (and any other rangefinder) will output to Sonar Range. Is MinimOSD able to display that parameter?"

"Hi Justin,
It appears that copter 3.3.3 does not support I2C for LightWare devices, however when I use the latest development version of 3.4 it works perfectly.
You also need to make sure you have the RNGFND_ADDR set to 85, which matches the…"

"There is a 'Zero datum offset' setting in the SF11 settings menu (Via USB). It's possible this may have been changed to something other than the default 0.00m.
Could you also confirm the distance error (using the USB connection) against some known…"

"Oh, and RNGFND_SCALING"
"Hi Cool Dude, can you verify what settings you are using for the following parameters:
SERIAL4_PROTOCOL
SERIAL4_BAUD
RNGFND_TYPE
RNGFND_MIN_CM
RNGFND_MAX_CM
RNGFND_GNDCLEAR"
SERIAL4_PROTOCOL
SERIAL4_BAUD
RNGFND_TYPE
RNGFND_MIN_CM
RNGFND_MAX_CM
RNGFND_GNDCLEAR"
"I'm pretty sure that serial 5 is not usable for a range finder. It acts as the debug port for the system."
"Hi Jeff,
Yes, the 0x55 address would be 85 for the RNGFND_ADDR in Mission Planner.
I've been looking into the issue of connecting LightWare devices with I2C to various versions of ArduCopter, I'll let you know anything I find out."

"I'm doing some connectivity tests with the various Copter versions and LightWare devices. I'll let you know as soon as I have some concrete information."
"Hi Al
Are you able to try Copter-3.4?"
