Re: yawing in specific height

Are you sure that your position measurement is working correctly? One way to debug would be to try first with using only the flow deck as a reference. If that works and you still get problem when using your own positioning input, there might be a problem with the position you are feeding to the Craz...

Re: Landing

But what do you have after, do you have cf.stop()? Have you tried having a sleep() after calling the landing function?

Re: Battery state

In our autonomous demos we have been using the "lowPower" state of the power management module to indicate that it was time to come back to the charger. This has usually worked quite well, by default the Crazyflie assumes the battery is low if it is read as bellow 3.2V for more than 5 seconds. The b...

Re: Square coordination

What is your exact python code? The code you wrote there would not work in python ( [] and () are reversed) so I assume this is not what is exactly in your script. The goto function takes a couple of arguments, are you giving them all (in you case relative should be false): https://github.com/whoeni...

Re: Landing

I have not seen that behavior in my previous tests, are you calling"sleep(2)" after calling landing to let the time to the Crazyflie to land before calling cf.stop()? Also something to check: are you sure you are calling with the right argument, the argument for landing in targetHeight and not targe...

Re: Frequent fly aways, toiletbowling and flips with Lighthouse positioning

A quick update, I ran some test and if there is any sensor that do not output data on the deck, the yaw code will indeed cause problem. The easiest way to disable it (without compiler warning) is to change this line: https://github.com/bitcraze/crazyflie-firmware/blob/af29d84/src/deck/drivers/src/li...

Re: PC Client unable to detect LPS

Hi,

The client problems do not sounds good and I wonder where that can come from.

By no-responding do you mean that the client looses connection to the drone, of do you mean that the graphical interface freezes?

What OS are you running and how did you install the client (from source or build)?

Re: 2.0 vs 2.1

Hi, There is a description of the difference in the blog post announcing 2.1: https://www.bitcraze.io/2019/02/the-crazyflie-2-1-is-here/ So the main changes are 'fixes' and sensor upgrade. Overall everything is still compatible software and deck-wise. It is almost one year after the 2.1 release now ...
