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

Re: Using v2 lighthouses facing upwards
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...

Re: Using v2 lighthouses facing upwards
Hello. I have been refreshing my knowledge on rotation matricies and wanted to propose a better way to mesh these coordinates together. If we took three readings from get_bs_geometry.py in three seperate positions. we could chain the reference frames together right? (it has been a long time since I ...

Re: Voltage sag on old batteries resetting the LH deck
Ok great to hear! I would like to also add my two fixes to reduce the chances of this bug happening. 1) add the cut out voltage in the firmware. the critical sag voltage added in a previous post has been working well. somewhere between 2.65 and 2.7 catches most of the faults. 2) gradual take off of ...

Re: Logging validAngles resets the cf
Thanks, rather than start a new issue I thought I would comment on issue 679 instead( https://github.com/bitcraze/crazyflie-firmware/issues/679 ) Also, if you do git rid of validAngles, I think my code would become clunky. I am moving to a multi lighthouse setup and want to make sure that the logged...

Logging validAngles resets the cf
Hello.
Looging validAngles in a script or just turnign it on as a logged block in the client resets the crazyflie. Is this a bug with this new variabe?
It has been very handy so far through the LED ring I want to use it in my scripts.
Cheers

Re: Using v2 lighthouses facing upwards
Hi Kristoffer! Thanks for the reply. I have three Q. 1) what do you mean by using channels 0-3 (1-4 in the lighthouse GUI). Are you reffering to the HTC software? 2) In a larger system where all base stations are not visible from the origin, it is possible to make multiple measurements with the Craz...

Re: Charging unprotected batteries via USB.
Hi Tobias,
Thanks for the suggestion. I implemented the code, the 'pmSystemShutdown' function did not seem to be able to be called unless I uncommented the line below from the config.h file.
