It is possible to flash it with a JTAG dongle but that is the only "wired" flashing supported now and I guess you don't have one?
Can you try to connect to the bootloader again and print the output from the command prompt here?

#2 is still under development but hopefully soon it will work. http://forum.bitcraze.se/viewtopic.php?f=10&t=180#p1090

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.

This is very strange. File "../cflib/bootloader/cloader.py", line 171, in updateInfo cpuid = struct.unpack("B"*12, pk.data[10:]) struct.error: unpack requires a string argument of length 12 It indicates that it managed to connect to the bootloader but doesn't get the right inform...

Thanks Tobias, this solution worked at least for me

Wow, didn't really expect it to work, cool!
Can you also report back if it is flying as before and especially when hovering?

It is not possible to overwrite the bootloader so you should be able to flash it again. It seams there is a corrupt FW in the crazyflie that's why the leds go out. Can you try: * Restart the cf-client. Sometimes it seem to help. * Make sure to run the Crazyflie from the battery when you power it up ...

Leap Motion + Crazyflie = Awesome!

If it is possible to make the Leap motion device work as a normal joystick driver and make it report 4 analog axis values it should be possible to map it directly in the cf-client.

Another way is to make use of the cflib.

Great work Anton, I'm looking forward of trying it out! Some thoughts. I'm actually thinking the battery wires and connector are the biggest cause of the dynamic magnetic field distortion. The motors are already so magnetized that the electric magnetization shouldn't do much of a difference. The mot...

I have put up another way that works pretty well to fix broken PCB arms in the troubleshooting section.

Great explaining pHysiX!
One cool and great thing would be if we could make the values auto adjust to the propeller balancing test.
