No dice still This is beyond frustrating! I did a fresh install and followed the steps to the T with everything working but the CrazyRadio will not transmit a signal. Both lights are on and the PS3 controller is plugged in. Inputs are reading on the PS3 thumbsticks and CF is powered on. All 4 props spun in the correct direction but still can't get the Crazyradio to transmit a signal. Even swapped the PS3 and CRadio dongle around to different USB plugs and PS3 controller works but Crazy Radio doesn't transmit a signal. What gives? Who wants a Crazyflie 10DOF RTF for $125?

I think I'm having similar problems with my MacBook Air USB 3.0 I'm pretty sure I was able to flash the CrazyRadioPA with latest firmware from github, and I used the brew install to get python running, but had no real luck until I did the macports install. Now when plug in the radio it shows up, and when I start the client I get one blink on the red light, and I see this in my connection window:

radio://0/80/250K
debug...

I try to connect and I get the following in the logs:

And the following dialog pops-up

Any ideas?

Thanks!
