Migration to bitcraze.io

Hi, I am currently migrating the bitcraze websites from bitcraze.se to bicraze.io in https. The plan is to do that is a seamless way: all links will be redirected 1 to 1 so there should be not dead link. Also I plan no service interruption. However as things goes seldom as planed, I will move the fo...

Re: Smooth perpendicular lifting

Hi, I would just add that the drifts and instability are even worse near the ground and if you are starting from ramp.py you might stay too much near the ground. I have been testing a bit sending 'timed' commands to the copter (something like "60% thrust for 2 sec then 30% thrust for 1sec to stop th...

Re: Retrieving data?

Hi, To get data from the copter you can use the log subsystem: http://wiki.bitcraze.se/doc:crazyflie:dev:arch:logparam The python client is already capable of recording CSV files out of log value. It is located in the "Log Block" tab (view/tabs/log block). If you activate writing to files you can fi...

Re: Crazyflie Mapping?

Hi qubitter,

Can you please start a new thread, I think it is an interesting question and it would be best in its own thread.

Can you precise what you want to achieve? Do you already have some autonomous control in python and you want to move it in the firmware?

Re: VM will not open in VMplayer Please HELP

Hi, I tried with VMWare player 7.1 and it works well, there is just a warning about the ova file but that passed it imports the VM. Also unfortunately importing the extracted vmdk as I described does not seem to work with vmware so this does not seems to be an option. Maybe you can launch again your...

Re: VM will not open in VMplayer Please HELP

Hi, What version of VMWare on what host system are you using? If you downloaded via torrent there should not be any corruption problem with the file itself so maybe you are using a version of vmware that cannot read it. The OVA is in fact a .zip file that contains the vmdk hard-drive and a descripto...

Re: Soldering accident resulting in poor radio stability (CF

Hi, It sounds like the Oliver's code is a bit too picky about packet lost and that is causing your disconnections. Have you tried changing channel and datarates? It could affect the radio quality. Also you can try to make the Oliver's client a bit less picky by changing the maximum number of re-tran...

Re: Crazyflie Documentation

Hi Guys, Why are you copying the project in another folder? The Virtual machine is pre-setup to have all our repos cloned in the same directory and Eclipse already have the crazyflie firmware in the workspace. I am suspecting there is some documentation somewhere that pushes you to clone somewhere e...

Re: Problems with extension port and stabilization

Hi, You need to connect the LED to one of the GPIO using a resistor to limit the current. You can find a lot of documentation on the internet about that for example for Arduino: http://arduino.cc/en/Tutorial/Blink. Now depending of the kind of LED you want to use it may be much more complex (power L...
