Hi. I got a crazyflie 1.0, and failed to operate this. PC client callback these errors.

-------------------------------
I don't know about kernel?(linux?) or Python, but I think that 'Too many packets lost' occurs by KeyError.
I try to know "what is the LogTocElement.types??", but I'm stupid, sorry;;

Crazyflie heartbeat by Red LED -> 2Hz = every 0.5s -> but flie doesn't work... why?
XBOX Controller -> Nothing problem driver, and PC client can read movement(pitch, etc.) values by controller
Firmware -> I just download from wiki's way... 'Crazyflie_2014.01.0.bin' installed inside crazyflie,
and I installed Dongle driver by zadig (because I using Windows 7),
and Client is 'cfclient-win32-install-2014.01.0.exe'.
Do I install something wrong files?

I hope that this hardware can be fly. Thanks to read.

I would recommend flashing the newest firmware and using the latest client. Both are available as source at the BitCraze github. I've compiled the firmware as of 2015-02-11 for the CF1 and posted the binary here for everyone's flashing pleasure, if you don't feel comfortable building it yourself.

Next, if flashing doesn't help, change your data rate to 1M or 250Kb again. 2M has always been error prone for me, even indoors and close to the radio. Those rates should really be reserved for the CR PA.

If errors persist on the newest firmware and client, please reply with a log encapsulated by the

THANKYOU!!!! Is that... error of bin file?? I think. Your new firmware is no problem for operation.
can fly... Thank you!

Glad my build helped at least one person out! It was most likely a firmware issue that got fixed in the past year. I know a few of them have popped up. Have fun, and I hope you take the chance to build the firmware yourself so you can keep up to date with all the changes.
