Re: Using Optitrack MoCap, but no ROS
Great! Please consider sharing a simple example script if you get it to work. No, the flow deck is not required. Flow together with absolute positioning may even confuse the kalman estimator, it is better to not use them at the same time. You can either force the Kalman estimator to be used, or use ...

Re: usage of Node like range estimator
Yes you can. If you use a LPS Anchor, the two way ranging mode will almost work out of the box for what you want to do. All you need to do is to modify the code here https://github.com/bitcraze/crazyflie-firmware/blob/2020.02/src/deck/drivers/src/lpsTwrTag.c#L253-L262 This is where the range has bee...

Re: Using Optitrack MoCap, but no ROS
Hi! I have never used an Optitrack system but I have done it with a Qualisys system and assume the process will be similar. The easiest way is to do it in python. First step is to find a python connection for the Optitrack system where you get the position of the Crazyflie. Second step is to feed th...

Re: Lighthouse deck and USB serial port communication
I must admit that I'm not completely sure how the bootloader works (it is probably documented in the lighthouse-bootloader repo), but what is working for me is to flash it while booting. The first time with a new binary I get (running from the lighthouse-fpga repo file tree) lighthouse-fpga kristoff...

Re: tcxo crystal should be improve the accuracy
my doubt is tdoa 3 send a packet about random 30ms, the packet record the tx timestamp, and other anhcor receive and record the rx timestamp, badly, if the two packet time interval is 30ms, when you calc the distance diff with two anchor, I think the clock correction error is large From what I have...

Re: Lighthouse deck and USB serial port communication
Are you sure USB-to-UART is working on your machine?
Which OS are you on? I'm on OSX and I had to install a driver (https://www.silabs.com/products/develop ... cp-drivers), it is apparently not supported out of the box.

Re: crazyflie firmware and c++
Hi! I know Arnaud looked at C++ at some point, but as far as I remember he ran into some kind of problem, not sure what though. We did not have the app layer at that time, it might be possible to get that to work? I found this thread that might help you? https://www.freertos.org/FreeRTOS_Support_For...

Re: Lighthouse deck and USB serial port communication
Hi! I think the problem might be that we are working on the lighthouse-fpga project to add Lighthouse V2 support, and that the code has changed recently. If your deck has the stock binary it is not compatible with master as the protocol has changed. You should probably look at the scripts in the V2 ...

Re: Software issue
I mean do you use Windows, MacOS or Linux on your computer? I read the post, though I don't know how to do that: "In the mean time, could you also downgrade the cflib to one from 2017 ? (I think you can do it as pip/pip3 install --upgrade cflib==0.1.3)" To clarify. In a terminal window, ru...
