How to communication between CC2540 and external Bluetooth using BTool/HostTestRelease project

Hi,
I want to communicate between SmartRF05+CC2540EM and external Bluetooth device such as iPad or Android. Referring to this site, I setted up CC2540EM and ran step by step. It was well up to Step 3 and GAP_AuthenticationComplete event returned and GAP_TerminateLink event ran and device disconnected automatically. But I do not know how to reconnect it shows in Step 4.External device still showed CC2540EM as paired device. If BTool sent GAP_MakeDiscoverable command in that state, it could not discover CC2540EM. To reconnect between CC2540EM and external device, which commands should I use?
And I want to know how to communicate between CC2540EM and external device using BTool.
