Fly higher than 2m using Flowdeck

Is there a way to bypass the height value in the following command and use the altitude calculated by the pressure sensor to hover in higher altitudes while using other parameters (Vx, Vy, yaw rate).

cf.commander.send_hover_setpoint(Vx, Vy, yaw, Height)

Re: Kalman filter position update requirement

Thanks for the reply. Now the kalman estimator seems to be working. I'm using flow deck with the crazyflie. I have another question. Kalman estimator shows the best estimate of the current position. Assume we are moving in a closed loop path. How can we use several particles to track the position wi...

Kalman filter position update requirement

Does the Kalman estimator require Loco positioning nodes to work correctly? I'm reading the x,y,z position data from the kalman estimator log and x position stays at 0.5 even the Crazyflie move in the x direction. Further, I would like to know whether this estimator works if we move the Crazyflie by...

Flow deck parameters

Could someone please explain what are the meanings of following log parameters in flowdeck. LOG_ADD(LOG_UINT8, motion, ¤tMotion.motion) LOG_ADD(LOG_INT16, deltaX, ¤tMotion.deltaX) LOG_ADD(LOG_INT16, deltaY, ¤tMotion.deltaY) LOG_ADD(LOG_UINT16, shutter, ¤tMotion.shutter) LOG_A...

Re: Accessing the RadioController inputs

Now I can understand it.I have 1 more question. While using the previous command generating code file, how can I send data to computer using the radio. I did it using 'DEBUG_PRINT' before using the 'sequence.c' code. To clarify it more let's assume that we are using a for loop to navigate the CF in ...

DIY SLAM deck

I'm trying to detect obstacles infront of the CF using a front mounted ToF sensor (Adafruit brekaout board for VL53l0X). After connecting the I2C lines of the ToF sensor to CF it doesn't detect the flow deck. Can you please tell me what modification are recommended to do to read the values from ToF ...

Re: Accessing the RadioController inputs

I got your point. Can you tell me what code part should I include for the "sequence.c" to go to the hover mode when it's needed, because it's more stable than just setting the altitude from the setpoint command.

Re: Accessing the RadioController inputs

The commands are generated inside the code as in the figure 8 code. But there we can just give only Vx,Vy,Z and yaw rate and we use the flow deck for that. My point is if we use another sensor system for CF and develop an algorithm to generate commands onboard, how can we input them to the system? A...

Re: Accessing the RadioController inputs

Thank you for the reply. That is very helpful. Further, I need to know how to send commands same as the radio without using the radio. As an example, I would send 60% throttle for 2 seconds and hover command after that. Where can I enter this code part?
