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!

How to log position data from LPS without Kalman estimator?

Hi. Is there any raw position available in LPS so to get the position direcly bypassing the Kalman estimator? Is there any value available in the TOC before applying the Kalman estimator? If not how do you suggest I could get the direct position from LPS? I want to get the raw position to experiment...

Re: How to dynamically change the log interval of LogConfig?

Thanks for the quick and detailed answer! For now, the current implementation does meet my requirements. In case I need more responsive interval modifications, I will follow your suggestion and take a closer look on the LogConfig implementation.

SOLVED: How to dynamically change the log interval of LogConfig?

Hi. I am currently working with Crazyflies 2.0 and Road-Runners. I am successfully gathering data from the devices, such as the stabilizer and loco position values using Python and the LogConfig class. Is it somehow possible to alter the "period_in_ms" value dynamically without disconnecting and con...

Re: Cannot run Python examples on Windows 10 -> libusb0-dll:err

@tobias: thanks for your support. it's now working fine with Python 2.7.15 and Python 3.7.2. I switched to libusbK (v3.0.7.0) together with Python 2.7.15 which worked for me. Today I tried your suggestion and installed Python 3.7.2 and re-installed cf-lib. It's now also working fine with libusb-win3...

Re: The position data of crazyflie

I have modified the ‘basiclogSync.py' to obtain the value of 'stateEstimate.x, stateEstimate.y and stateEstimate.z'
@liuyuzhen: Would you mind to share the altered code you made :) ?
