After near tree months I recived happy the Lidar Lite V2, but now I have a concern because, apparently is discontinued?
something wrong with this thing?
It's a risk to put on my quad? :(
Answer I recived: Lidar was purchased from Garmin, so It's going to re-appear under Garmin name.
Now is in the market Lightware, developing altimeters for Ardu pilot and helping rangefinders users in this forum ( http://www.lightware.co.za/shop/en/4-drone-altimeters. )
I changed the title because this post discussion content look's usefull for other rangefinders too.

Congrats for your promotion Cala:
Darius Jack replied toOsman Kültür's discussionHow to write Conceptual Design ? in the groupArduCopter User Group
Thank's Paul: I'm going to promote a Lidar on sale I hope. LOL
I hope not good to promote Lidar, now works but looks unstable specially at low altitude, I'm not shure if I need to tune something or what happens but don't looks safe to fly like this.
Here I open a discuss and logs http://discuss.ardupilot.org/t/lidar-lite-v2-unstable-at-low-altitu...
Any idea?
@LaserDev Do you have any experience connecting an SF11 directly to a companion computer? What connection do you recommend. I would have done i2c. However, I'm using an Odroid XU4 and the i2c is horrible. It's a good board in general but the i2c implementation presents challenges.
@David Mathias - this is a very interesting subject because SBCs running Linux or other high end operating systems isolate the programmer from the hardware interfaces making it impossible to use commands that you would typically find in embedded systems. As a result it is necessary to use the standard port and driver combinations provided for by the OS, such as the serial port or USB port.
The SF11 can connect to either type of port by switching it into "free running mode" and then treating the data as though it was a conventional serial transmission, meaning that the Linux commands simply read the data buffer of the port and not the port itself.
If you would like to chat to someone who connects our lasers to SBCs running Linux every day, then feel free to PM our software guru, Robert Gowans. You will find him listed as a member of this forum.
@LaserDev - thanks very much. Our SF11 arrived just yesterday so I'll ping Robert to see if we can figure something out. Appreciate the help.
Two questions:
1) What happens if the Lidar disconnect or fails in pos Hold? change to baro? ....land?........crash??
2) Tower don't support, no?
I'm installed with little angle like Laser recomends (I don't know why I can't upload photos I try later.)
@Cala - these are really important questions about how to use any type of laser sensor reliably. We have taken on a full time programmer to work through the ArduPilot software and test the existing features as well as add new functionality that provides for "fail safe" operations. This will take some time but should result in a more reliable system especially when there are component failures.
Thank's Laser, another usefull thing, perhaps It's to have the possibility of a switch (eg ch6-7) to switch between the two systems because sometimes is more usefull the baro not to jump everything under you are flying.
If you agree I can change the Title to include your products because this post have info for them too and Lidar is out of market now.
That's a good technical suggestion Cala - automatic switching between different systems in the event of a failure or an unreliable result.
Thank you for offering to change the Title, if you think it will help you are most welcome to change it, otherwise we could start a new thread with a different title.
