Hi,

In the log toc it is called Acc.x .y .z.

The crazyflie-lib-python repository contains an example file called basiclog.py or basiclogsync.py that you can use as an example to read out a log.
Hi Kimberly,
Thanks for your reply.

Re: radio lost connection after actuate the 5th motor

Hi! Where is the 5th motor located? Is it near the antenna? It is indeed a bit weird that it does not lose connection if you do not fly it and actuate the 5th engine. Are you sure it is not drawing too much current? Flying 4 motors is already takes up a lot of power for the tiny crazyflie ;) Hello,...

Re: Cannot initilize Client in Linux

Are you using the latest version of the VM (2018.12) ? The previous version was running an old version of linux that could cause dependencies problems. To answer your question: the latest VM is capable of running the latest commit of the client and supports the flow deck, so this should work fine. ...

Re: Cannot initilize Client in Linux

Hi, I typed exactly the same commands in a fresh Ubuntu 16.04.5 VM and it works well without any error. This could come from a python package installed by another program. It seems to come from numpy so one thing to try is to uninstall and reinstall nympy with "pip3 uninstall numpy" and "pip3 insta...

Re: Cannot initilize Client in Linux

There seems to be a problem with the dependencies. Have you installed the client by typing "pip3 install -e ." from within the project folder? More generally could you describe the step you did to install the client? What linux distribution and version are you using? I fork and clone the crazyflie-...

Re: Problem when using flow deck

Your windows problem looks like the USB driver was not installed for the radio. Did you install the driver using zadig as described there: https://wiki.bitcraze.io/misc:usbwindows? Hi the usb can be recognized. I am wondering if there is available client in the Linux VM to use the flow deck. And is...
