Re: BigQuad deck and target tracking with an on-board camera

I can't think of a way to do this without modifying the firmware. It requires updating some files but not impossible to do. First of you should run the kalman filter. Then into this you can inject height measurement. See the zranger as an example . To get the values from the PC to the crazyflie use ...

Re: tdoa data of Crazyflie

I believe the LPS is not accurate enough to archive what you want. You need a more high precision system such as the lighthouse or a MoCap system.

Re: Autonomous flight wiith Flow Deck V2 only

Do you maybe have an old firmware. At some point the initial position was not zero and I cant remember why but that was changed. The initial position is set here. Are you sending a reset of the kalman filter at some point? If not, it is probably a good idea.

Re: Controlling motor

Do I understand you correctly that you would like to control the brushed motors both CW and CCW? Please explain what you mean by "crazyflie to round opposite"

Re: flow sensor lens incosistnecy

That I would say is a mistake from us (Bitcraze). The new lens should probably have had a new SKU but we were told the new lens was a drop in replacement for the old one... The good news is that the version with the bigger lens (lens sticking out) is the new one current in production and if you orde...

Re: Camera wifi

Could you please give us more background information, e.g. what exact hardware are you using. Also, WiFi cameras tend to have large lag times and I'm not sure you will be able to do something about that.

Re: Crazyflie 2.1 External antenna compatibility

Hi and welcome to the forum! Some basic documentation about the external antenna can be found here . - Is it a true antenna system or does the included PCB antenna get disabled when an external one gets connected? No, you will have to, in compile time, select one or the other. - Are there any models...

Re: Modifying the loco positioning firmware

Sounds interesting, please share more about you work :-). I'm guessing it gets stuck waiting for something, possibly a response from the dw1000?

Re: Can I install the developer VM image natively?

You could start trying to setup the environment on windows. There is a guide here, might be a bit outdated, but a good start.

Re: micro-SD deck log only zeros for PID controller commands

The Flow deck and the SD card is sharing the same SPI buss and that is probably why. Maybe it is possible to optimize the communication a bit to improve that. I've also seen hacking the SD card to use another SPI bus an then it should work better, please see this issue.
