Hello.

I can not connect to Revolution in LibrePilot.
I can connect to cc3d but cc3drevolution not.
What can it be?

Thank you.

Seems legit, the "Revolution" is not a know board. 
There is CC3D boards and Revolution boards.

What about blinking ?
Do not connect both boards at same time.

I own the two boards,


connect the cc3d in librepilot normally.
 But the revolution can not. The windows emits sound when I plug the revolution, but there is no link with the librepilot. in revolution flashing orange light twice fast and slow blue

the Windows device manager. see "coptercontrol virtual com port (com10) to cc3d
and  "revolution virtual com port (com11) to revolution.

Reinstall the driver, be sure you uninstall/install the right "USB composite device"
