Description

The header file btserversdkcrkeys.h includes Central Repository keys for controlling the Bluetooth power state. However, setting the power state to EBTPowerOn does not switch Bluetooth on even though the status icon indicates that it is activated.

How to reproduce

CRepository* cenRep = CRepository::NewLC( KCRUidBluetoothPowerState );
TInt state, err = KErrNone;
cenRep->Get( KBTPowerState, state );
if( state == EBTPowerOff )
{
err = cenRep->Set( KBTPowerState, EBTPowerOn );
}
CleanupStack::PopAndDestroy(); // cenRep

Solution

Use the Bluetooth Notifier API to switch Bluetooth on.
