Unstable flight+ can´t connect over USB

[martinez22]

Hi All,
our company won Crazyflie 2.0 in the Hackaday Prize, but when we try fly with it the CF is very unstable and the quad drift over ground.

I downloaded too the VM Bitcraze Machine, updated all project on the last state, but when I click on the Connect, the quad do a self test which fail (the RED M1 LED seems like this https://vine.co/v/Or39eVaZxr1), I can not see any Battery state, Console writing or anything else.

Thanks for response

Hi martinez22,

Congratulations on the prize! The CF will be quite unstable close to the ground - rotor wash will cause a lot of drifting. Higher in the air (at least a couple feet) should be better.

Plugin in the CF with USB (make sure the battery is disconnected) then, in the client, connect to the Crazyflie by selecting "usb://0" from the "Select and interface" menu. Then click the "Connect" button. After this what does the Console tab in the client show? The red LED flashing pattern you linked to is a POST failure and the console will likely display an error.
