Bluetooth 4.0 le problem

[Willyfan]

Dear Werner, As I have a lot of problem with recent android with bluetooth 2.0, so I tried to connect some 4.0 le board. I set board from pc by terminal, and connection from phone and pc using a usb serial adapter is working. But if I connect the board to cc3d it don't comunicate. I done a lot of experiments, without luck. Can you help me about this? Maybe sothing must be change in the source code, or maybe you know a board that work. Many thanks
