Great. Thank you for your answer. I might try both to see which one fits my project the best.
Thank you and happy new year!

Try to figure out the ROS package
Hi all, I am new to ROS and I would like to use the Crazyflie ROS package along with a SLAM ROS package to realize autonomous flight. I have installed the Crazyflie ROS package on ROS and try to go through this tutorial ( http://act.usc.edu/publications/Hoenig_Springer_ROS2017.pdf ). I have some exp...

Re: Autonomous flight wiith Flow Deck V2 only
Hi Aren, I am doing something similar and I am curious how you realize this "The output of my controller is then sent to the python software and via crtp to the crazyflie itself". Are you using the python software to control the crazyflie and if your controller is on ROS, how do you feed t...

Re: struct.error: unpack requires a buffer of 1 bytes
Thank you very much. If always keep the logging then it would require something like the threading, right? Since the data collection would only happen in some situations, I still hope the logging could start and stop. Could you share with me some materials and resources about the async log API? I do...

Re: struct.error: unpack requires a buffer of 1 bytes
Hi Arnaud, I think I find another key to this error after I modified the sync log demo code to the way I use the log in my code. Here is the code: import logging import time import cflib.crtp from cflib.crazyflie import Crazyflie from cflib.crazyflie.log import LogConfig from cflib.crazyflie.syncCra...

Re: struct.error: unpack requires a buffer of 1 bytes
Cool. So I will try to the latest version and see whether the error happens again.
Thanks.
Duncan

Re: struct.error: unpack requires a buffer of 1 bytes
Hi, arnaud Those log readings are from the extra sensor through the Crazyflie so might be you could regenerate this error by reading other log parameters. The code below is the only log reading-related part in the client code. The firmware side to register log variables is similar to the "oa&qu...

struct.error: unpack requires a buffer of 1 bytes
Hi, I encountered some issues when I try to read the log variables. I write some codes to read the log variable and do some math. It work well at the beginning and read the desired log variables without any problem. But then, after updating a few hundred times, the code crashed and shows the followi...

Re: How to use EKF to estimate position
Thank you, Arnaud. Yes, using RSSI to do the position localization is not accurate enough but I am trying to improve it with all kinds of math models. EKF is a part of them. I watched the source code "estimator_kalman" in the firmware and the resources you recommended. As you said, with th...
