Re: How to log bare DWM1000 positioning data?
Thanks for replying and the additional information. I am relying on TDoA, unfortunately TWR is due to its contraints no option for my application(s). If I understand you and the kalman_core.c code correctly, the absolute position within the world frame is actually never calculated directly (on the b...

How to log bare DWM1000 positioning data?
Hi! As I understand, the Kalman filter is for sensor fusion to achieve more accurate positioning results (IMU/AHRS+Positioning Data). I am currently trying to log the DWM1000 positioning data before it gets into the Kalman filter, because I need the "raw" positioning data. For this purpose...

Re: Can I install the developer VM image natively?
Hi Tobias. Thanks for your quick reply. I meanwhile found a way to configure the USB devices so that they are accessible from within the VM. Now it seems to work, at least I can use the "flash using debugger" make target in Eclipse and the firmware gets flashed to the CF2 through the ST-LI...

Re: Error in crazyflie-lib-python ?
Hi Kimberly. Thanks for your quick response. I wasn't able to reproduce the error after I further worked on my Python code. Probably I somehow tried to delete a log while I was disconnected or the log wasn't started due to an error or something similar. So let's close this thread. I am sorry for the...

Hi. After some terrible hours (without JTAG debugger device) I meanwhile made some progress as well :D The ESP32 bridge is basically working and on the way to success I intermediately also wrote an USART driver link.
