Yeah, this is exactly the bug I need to fix this weekend. Mine sometimes hangs too. Rebooting the crazyflie & re-running can help. Also, running tip-of-tree master might help, because I have done some work on this. The root of the problem is that packets are getting dropped (not sure why yet) and I need to timeout fast & retry.

Sometimes it'll just work perfectly. No clue what's the root cause.
