Re: Fly two crazyflies with the motion capture

You can write a python script that connects to your mocap system and pushed the position (or full pose) to the Crazyflies. I'm not sure which mocap system you use, but we hava an example for a Qualisys system in https://github.com/bitcraze/crazyflie-lib-python/blob/master/examples/qualisys/qualisys_...

Re: Detecting deck to be updated no reaction

Hi! There is nothing in the Flow deck to update so the expected behaviour is that the CF should just look for update-able decks and after a second or two continue. Did your client stop at this point while flashing? If you have a drift with the flow deck it is usually because the floor under the craz...

Re: Random Behavior while hovering/flying autonoumously

I can see in your code (https://github.com/AliGriv/Crazyflie_te ... ain.py#L92) that you log the yaw-rate while the Crazyflie set point function taks an absolute yaw. Maybe there is a mixup between rates and absolute angles?

Re: Random Behavior while hovering/flying autonoumously

It looks like your controller is increasing the thrust when the CF starts to descend (after t=25s) but that it does not help and the CF is continuing down anyway. Are you running the stock firmware or do you have any modifications/decks that might change the normal behaviour? I had a quick look at y...

Re: Ways to increase power to the active marker deck IR LEDs?

Hi! The best way to store this information is probably in the persistent storage of the CF, there is some documentation here https://www.bitcraze.io/documentation/repository/crazyflie-firmware/2021.03/functional-areas/persistent_storage/ This way the ids will be connected to the drone. The functiona...

Re: Sequencer LED ring effect

"16: Location Server Status" is showing the status of the location service which is used by external positioning systems such as mocap systems.

Effect 18 is showing the reception of the lighthouse system, it is currently only implemented for lighthouse V1 systems

Re: Hardware Issue

Yes, you can use CF + battery + 15g

Note: 15g is not an absolute max weight in the sense that it will not fly at all with 16g, it is a tradeoff between flight-time, agility, stability and so on.

Re: Sequencer LED ring effect

Hi! There is a pyton example here: https://github.com/bitcraze/crazyflie-lib-python/blob/0.1.14.2/examples/basicLedTiming.py As far as I know the functionality is 1. Upload a sequence to the RAM of the Crazyflie. In the python example this is done in https://github.com/bitcraze/crazyflie-lib-python/...

Re: Lighthouse Deck Red and Blue LED Remaining On

I'm glad it worked out!

Yes, it is important that the python lib is updated as well
