Re: Can't control more than 3 CFs with one radio

Currently the easiest way to use broadcast commands in that way would be to modify the Crazyflie ROS driver/crazyflie-cpp since it already handles it concurrently with normal connections. When using the python lib it would require either to connect for sending trajectories, disconnect all and then ...

Re: Script to compress trajectories

Are you talking about this pull requests: https://github.com/bitcraze/crazyflie-firmware/pull/504? If so, the format has been documented (https://www.bitcraze.io/docs/crazyflie-firmware/master/trajectory_formats/) but I have never tested it and I am not aware of any script that can generate it. Fro...

Re: when exist metal or wall, about tdoa3

I use the tdoa2 and tdoa3 in a room with mirrors on the wall and the system has very poor performance, specially when the CFs fly near to the walls (mirrors) and there was a zone where z axis seems to be higher than in others,(all the cfs rise a bit when they flought above that zone). I change the l...

Script to compress trajectories

I don't understand how to convert a Raw representation to the Compressed representation, maybe if you have any example or script, it will help. Also, I have question: if a single segment requires 132 bytes, how many bites does the compressed representation need? I really don't use te 7th degree poly...

Re: Can't control more than 3 CFs with one radio

Is it posible to communicate with all the CFs (16 in my case) in a multicast way. I mean in my particular case the content of the transmission is exactly the same for all, i don't need to connect to each one individually. The trajectories are different but are already loaded in memory, all i send by...

Victor propeller and motor test program

In a recent post on the blog Victor wrote about a program to test the propeller and motors, we found the script very useful but hard to implement, is there any documentation? We install tkinter and run it under the cfclient directory and terminal. It opens the interface but reports an error. Any adv...

Re: Uploading multipe trajectories, and overwriting trajectories in memory.

Hello Lupo, some tips from my experiencies: >>>First, I am having trouble setting several trajectories. This example demonstates how to upload, set and fly along a single trajectory, but I have been unable to generalize this to more than one. "upload_trajectory" can be used twice, with two different...

Can't control more than 3 CFs with one radio

We finally could flight a swarm with 15 drones but changing addresses avoiding that they were consecutive in the same radio and using 5 radios as you can see in this video:( the goal is a swarm of 16) https://drive.google.com/file/d/1-Cp3o-yxRNSFMBQHXZ0vGhzD45kLGLdP/view?usp=sharing Some of them sim...

Re: How to control more than 50 crazyflies?

Hello Arnaud than you for your answer. Some of them restart and others lose connection. Another possibility may be a lack of feertos heap memory, because I decrease the assignment to 36000kb, (making room for the trajectory in flash memory) But I don't see how the quantity of CFs can be related and ...
