Hi,

 

I made a board with CC2540. I'm testing the connection between my board and a USB dongle with host release firmware (CC2540_USBdongle_HostTestRelease_All).

I have been having problems with this comunication. When I made a Scan (with BTool, I can see the peripherical (my board), but I try to connect that, the connection fails.

you can see this,
