There used to be a similar problem on OSX, see https://github.com/bitcraze/crazyflie-c ... issues/308
QT is usually the problem, it might be worth trying another version.

Re: Android phone as controller for Betaflight flashed CrazyFlie 2.0
Hi!
Sorry that does not work. As far as I know they do not use the same protocol

Re: Light House Position question
it looks like you have not set CENTER_AROUND_CONTROLLER = True (see the wiki page) It centers the coordinate system around the tracker, as opposed to one of the base stations. The data you get from the script is a vector from the origin of the coordinate system to each base station (.origin) + a rot...

Re: indoor position tracking with 4 anchor and 10 tag
Hi! Just follow the getting started guide https://www.bitcraze.io/getting-started-with-the-loco-positioning-system/ using ids 0 to 3. You don't have to do anything special, the anchors synchronize using the UWB radio. If you plan to do 3D positioning, 4 anchors might be a bit too few. If you only wa...

Hi!
Just to clarify, does it work with LPS + Crazyswarm?

Re: LPS node set up ROS
Yes in most cases. The scripts that require positioning support can be used with any positioning system as long as it provides the properties needed by the script. If you are using the LPS for positioning, the Mellinger controller will most likely not work (LPS is a bit too noisy) for instance, but ...

Re: Get raw measurement from the flow deck V2
There are two examples in the python lib repository (examples/basiclogSync.py and examples/basiclog.py) that is a good starting point.

Re: crazyflie 2 won't take off properly commander.send_position_setpoint
shouldn't the height displayed in the flight data be read from the altimeter? The barometer is not used by default. It can be enable it with a compile flag though. As long as the configured anchor position is within +-5 cm of their real positions, it should be OK. There are log variables for the di...

Re: Communicate with Crazyflie2.1 without Dongle
The easiest way is to use USB if that works for you. Just use usb://0 as your URI when connecting to the Crazyflie in the python lib

Re: Data logging not working from python script
Hi! The spurious "Error no LogEntry to handle..." messages are harmless. You may get them when re-connecting to a Crazyflie where some logging was set up in a previous connection. Due to the design of the protocol, the Crazyflie does not really know if a connection is new or not, and will ...
