Hi Kristoffer, As an extension problem to this post here. https://forum.bitcraze.io/viewtopic.php?f=20&t=4668&start=10 I will be getting the CF to look for more than two basestations.

Re: Using v2 lighthouses facing upwards

I tried again in our lab, clean install new drone. all works ok! So not sure what that was.

From this old post https://forum.bitcraze.io/viewtopic.php?p=16079#p16079 Tobias flipped the signs in the powerDistribution function definition. I gave it a quic...

Re: Using v2 lighthouses facing upwards

I can't even get the drone to fly with the latest pull, with unmodified firmware, client and cflib... So i will try to get it fly on a multi bs setup with hard coded geo/calib values first. Then we can talk about moving it over once the tab/lib and firmware is more stable and there are docs... Sould...

Re: Using v2 lighthouses facing upwards

Hi Kristoffer, I checked out the latest version of the lighthouse positioning tab today in response to Tobias's battery test function blog post. It looks like the calibration and geometry data are no longer hard coded into the firmware? How do you define the origin now? I assume there is some docume...

Re: Using v2 lighthouses facing upwards

Hi Kristoffer,

Super exciting to have finally reached some precipice!

I have an engineer friend to help me from this point forward. He wants to know how does the rotor reference frame come into play.
is it something we need consider in this problem?

Cheers

Hello! So I had a look at the script you posted (thank you) I did two things here. 1) Took 4 measurements in various places on the floor with the CF facing upwards, and 4 measurements in various places on a platform 1.2 m high. The script does seem to smooth out a lof of the jumping around I would n...
