Hello,

I have a Crazyflie, I already followed the installation intructions. I have the following:

-- A 10 DOF CrazyFlie assembled, I guess it is well assembled, since when I turn it on the rotors turn in the right directions and the leds blink as described.
-- Crazyflie PC Client running on Windows 7.
-- I have installed Microsoft Visual Studio 2012 for Desktop.
-- I am using an Elecom PS3 like controller.
-- Crazyradio installed.

So, this is happening:

-- I open the PC client
-- Click on connect
-- The client shows:

radio://0/10/250K
debug://0/0 - Debugdriver for UI testing

-- At this point if I click scan, the green led on the Crazyflie blinks, that makes me think the Crazyradio is working right.
-- I click connect.

After connecting I am not able to fly the Crazyflie. The controller is responding since I move the joysticks and I can see the target values moving accordingly to the controller configuration.

Then looking at the output window I always get the same messages, which are below, I get an error related to an old timer and a warning related to an stabalizer.roll, but I cannot find the cause of them, can anyone help me??

Thanks!!!

I think it might be software mismatch. Can you try updating to the most recent versions.

Also make sure the red led is blinking about 2 times a second. That means it is calibrated and ready to fly. If it is only blinking once a second it is not calibrated and won't fly.

Hi,

Before you click Connect you should select the row that says "radio://0/10/250K". Looking at the log you attached you are connecting to the other URI, the "debug://0/0" and using this you cannot fly (this is only for debug purposes).

Hello,

I was not selecting "radio://0/10/250K" before conecting. Now it is flying, thanks!

i cannot see the URI when conneting to crazyflie..anyone knows how to solve this problem?
pls help..its for educational purpuses..thank you

The Crazyradio driver is probably not working. If you open the bootloader dialog in the cfclient do you get an error for the Crazyradio shown besides the status:?

If you will use it for educational purposes I suggest you start out with the virtual machine as it will get you going quickly.
