RBTPowerControl()

IMPORT_C RBTPowerControl ( )

Member Functions Documentation

Cancel()

IMPORT_C void Cancel ( )

Cancels asynchronous requests made through this handle to the power control interface.

panic
KBTPowerControlPanic EApiUsedWhenHandleIsNotOpen If called when the RBTPowerControl instance has not been opened.

Close()

IMPORT_C void Close ( )

Closes the handle to the Bluetooth power control interface.

Note that it is safe to call this multiple times.

GetPower(TBTPowerState &, TDes8 *)

IMPORT_C TInt GetPower ( TBTPowerState & aState,
TDes8 * aDesc
)

Makes a synchronous request to get the current power state of the Bluetooth hardware.

panic
KBTPowerControlPanic EApiUsedWhenHandleIsNotOpen If called when the RBTPowerControl instance has not been opened.

Parameters

TBTPowerState & aState Set (on return) to the current power state if request was successful.
TDes8 * aDesc

Open()

IMPORT_C TInt Open ( )

Opens the handle to the power control interface for the Bluetooth hardware.

panic
KBTPowerControlPanic EHandleIsAlreadyOpen If the RBTPowerControl instance has already been opened (and not subsequently closed).

SetPower(TBTPowerState, TDes8 *, TRequestStatus &)

IMPORT_C void SetPower ( TBTPowerState aState,
TDes8 * aDesc,
TRequestStatus & aStatus
)

Makes an asynchronous request to set the power state of the Bluetooth hardware.

panic
KBTPowerControlPanic EApiUsedWhenHandleIsNotOpen If called when the RBTPowerControl instance has not been opened.

Parameters

TBTPowerState aState The desired state.
TDes8 * aDesc
TRequestStatus & aStatus The TRequestStatus that will signal the result of the request when completed.
