Re: Having issues with lighthouse in new FW

Hm, that does not look right. I don't think this is related to the CCM changes though, as it works here. Have you tried to revert to the version before CCM changes? I tested with Crazyflie + Lighthouse deck + 2 x V1 base stations, latest firmware source code and all is fine. What kind of setup are y...

Re: Configuration of LPS

Hi! It sounds perfectly normal, your next step is to configure the anchor positions (see https://www.bitcraze.io/documentation/tutorials/getting-started-with-loco-positioning-system/#enter-anchor-positions) and write them to the anchors. If your anchors are brand new, there is no position stored in ...

Re: Would it not be possible to estimate height with just on-board sensors?

Hi! In theory you are right but the problem is that the accelerometers are too noisy. You can easily try it out with the normal firmware by switching to the kalman estimator without a deck (set param kalman.resetEstimation = 1). The kalman filter fuses information from the sensors that are available...

Re: Combining Motion Commander with Swarm

Yes it is possible, a good starting point is maybe examples/swarm/swarmSequence.py In run_sequence(), use the MotionCommander instead of sending setpoints directly. def run_sequence(scf, sequence): # We take off when the commander is created with MotionCommander(scf) as mc: ... You are right, the th...

Re: Running multiranger_pointcloud.py example

It is probably related to qt5 or vispy? Vispy is using QT but I'm not sure what the problem is. Have you tried to upgrade or reinstall vispy and qt5. You can do it from pip, and since it seems as your ide is using python 3, you should probably use pip3. on the lines of pip3 install vispy pip3 instal...

Re: stm32 debug

Hi!

You can find the documentation for the python client here https://www.bitcraze.io/documentation/r ... de_client/

You are probably looking for the section called "Console". The "Plotter" section may be helpful as well.

Re: Running multiranger_pointcloud.py example

I think it is more likely that it is related to vispy rather than python, and that different python versions may not use the same version of vispy. if you run python --version you can see which version you use of python. Is there any more information in the error message that you can share? A callst...

Re: Working with multiple drones

There is currently no way to flash multiple crazyflies in parallel but sequential flashing can be automated. See cload_all_nrf.sh and cload_all_stm.sh for inspiration https://github.com/bitcraze/crazyflie-lib-python/tree/0.1.10/sys_test/swarm_test_rig The channel/id is used for identification, see t...

Re: Control Crazyflie with Vicon

Sorry, my bad! That sounds a bit too much, the yaw should not drift that much with a Flow deck. You should expect something like this https://www.bitcraze.io/documentation/tutorials/getting-started-with-stem-drone-bundle/#the-script-in-action- If it is worse than that, please contact us as at suppor...
