Abstract
If a control section fails to detect a connectable device by Inquiry/Page_Scan before an OFF timer times out, the control section halts the Inquiry/Page_Scan. The control section keeps this state until time-out of an ON timer. Upon time-out of the ON timer, the control section starts Inquiry/Page. The control section issues a request for a role switch to the connectable device detected by Inquiry/Page. Upon acceptance of the request, the control section effects a master/slave role switch.
