Re: pitch, roll and yaw with ZMQ
There is a zmq version of the cfclient (which is installed with these instructions: https://www.bitcraze.io/documentation/repository/crazyflie-clients-python/master/installation/run_from_source/). Here are instructions how to set ports and such in zmq for that implementation: https://www.bitcraze.io...

Re: make more RAM available for app code
There has been a lot of changes since 2019.09 and we are aware of this problem that we are running out of memory. I think you are dealing with the issue mentioned here on the gihtub repo: https://github.com/bitcraze/crazyflie-firmware/issues/579, which also shows a list of how much RAM each process ...

Re: Control everything in one Controller
The python API explains how to set roll pitch yaw setpoints: https://www.bitcraze.io/documentation/repository/crazyflie-lib-python/master/user-guides/python_api/ from the pythonscript Soon we will add a functionality to do this for roll/pitch/yaw rate, which will be discussed in the link I send in t...

Re: Broadcasting with Crazyflie
An issue that i have right now with my setup is, that i also tried to build the Crazyflie-nRF-Firmware with SEGGER RTT, but it would not built because of RAM error. I assume that there is not enough space in the nRF-Chip. Nevertheless i would like to know if you guys use the SEGGER RTT Debugging co...

Re: Control everything in one Controller
Yeah sure, but you will need to deal with the delay that comes with the offboard controller. I don't know about the ROS side of things though but I can let you know how it works on the firmware (since it pretty much boils to the same thing). It is true that the mellinger controller looks at all thos...

Re: CF2.1 firmwire query for machine learning (ML) applications.
here is some more info with some help of @kristoffer! When the firmware is build, you see this information: text data bss dec hex filename 213344 5148 110236 328728 50418 cf2.elf the bss stands for the ram used by variables. So these are allocated with static task macros (also queues and timers) The...

Re: Broadcasting with Crazyflie
About scheduling the communication. Might also be an option to implement STDMA ? My old lab (the MAVlab at tudelft) implemented this on Bluegiga bluetooth dongles (https://link.springer.com/article/10.10 ... 018-9760-3), so it might be possible to implement this also on the NRF side of things.

Re: CF2.1 firmwire query for machine learning (ML) applications.
Currently I'm unsure how much RAM is still left exactly, but we do know it is getting less and less. This issue on the github repo is also discussing this current problem. About your questions: 1. The additional 64 kb is called CCRAM, which is used for uploading trajectories for the highlevel comman...
