Re: Hover instead of turning off motors

Dear Arnaud, thank you for your detailed reply. Can you please tell me if I understood your answer correctly? Scenario 1: Crazyradio -------------- Crazyflie low-level commander. Cuts motors due to safety, cause low-level commander does not know anything about sensors. Scenario 2: Crazyradio -------...

Hover instead of turning off motors

From this thread: https://forum.bitcraze.io/viewtopic.php?f=10&t=3486 If you are using low level commander setpoint and there is no packet for more than 1/2 seconds it is indeed possible to get into trouble: after 1/2 seconds the Crazyflie will try to level its attitude and after 1 second it will cu...

Re: Unable to get any geometry data from lighthouse v2 (valve)

Hi Kimberly,

we did not have to do the calibration, getting the geometry with the old firmware was enough ;-)

Re: Unable to get any geometry data from lighthouse v2 (valve)

Ok, so setting the 2 basestations to mode 1 and 2 and using crazyflie-firmware state from commit 463110b1aae6166fdecdcfca4d3bc64532e949bc we can get some raw angles as well as get_geometry. To set the geometry (I really don't know how to use --write flag since I never saw a valid command - could sb....

Re: Unable to get any geometry data from lighthouse v2 (valve)

I set basestation 1 to mode 1 and basestation 2 to mode 2. (sudo apt install picocom; sudo picocom /dev/ttyACM0; mode (shows e.g. mode 4); mode 2; param save; ) Is this correct? Since then I am getting some raw angles. But executing ~/projects/crazyflie-firmware/tools/lighthouse$ python get_lh2_cali...

Re: Linking lighthouse to crazyflie

Thank you for your reply - I am really looking forward to get my hands on. I guess you mean this repo state: https://github.com/bitcraze/crazyflie-firmware/tree/463110b1aae6166fdecdcfca4d3bc64532e949bc Is there anything wrong in the latest version or is it just the one you used and were satisfied wi...

Re: Linking lighthouse to crazyflie

Hi there,

I remember a blog entry where sb described the setup of basestations v 2 with the requirement to have a controller or sth. similar to calibrate the system.
Is it still needed or is a crazyflie with a lighthouse deck and a basestation enough?
