Re: Can I install the developer VM image natively?

I followed the instructions in the wiki here , but unfortunately I get the following error when trying to start a debug session in Eclipse CDT: Error in services launch sequence Launching command [/opt/gnuarmeclipse/openocd/0.9.0-201505190955/bin/openocd -c gdb_port 3333 -c telnet_port 4444 -f inter...

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-LINK/V2 auto...

Can I install the developer VM image natively?

Hi I just received my ST-LINK/V2 device and would like to make progress with my ESP32 deck project. As suggested by the online resources, I checked out the development VM together with VirtualBox on my Windows PC. But it seems, that I have issues with the USB ports, PC-Client doesn't recognize my Cr...

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...

Minimal requirements to keep propellers spinning?

Hi. I am currently experimenting with the "low level commander"; setting roll, pitch, yaw and thrust. I am using the def send_setpoint(self, roll, pitch, yaw, thrust) function. What are the minimal requirements to keep the propellers spinning? A.) Minimum thrust value (e.g. thrust = 10000) ? B.) Int...

Re: External communication not only CF Radio Dongle

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. Scan function for the ESP32 is also working and in PC Client the new link types (es...

Re: How to log position data from LPS without Kalman estimator?

Thanks for your quick and detailed answer. I am indeed highly interested in gathering the position data without the Kalman filter, since it unfortunately seems not to meet our requirements. I understand, that it's most probably the best solution for the Crazyflie quadcopter. We want to track people ...

Re: How to log position data from LPS without Kalman estimator?

Hi Arnaud. Thanks for your reply! We depend on TDoA, since we're going to use about 20 tags (RoadRunners & CrazyFlies 2.0) simultaneously. Since we experience some issues with the LPS positioning: A.) estimation inaccuracies while moving the tags fast -> "wrong" ellipsoid estimations B.) sometimes s...

Re: Why I cannot configure node position data ?

Hi Tobias. Thanks for your reply. Yes I used the *.bin files only. Now tried with the *.zip file and it updated the NRF MCU as well as the SMT32 MCU. Many thanks for the hint!
