Useful code, let's try it. I have already try this code in Symbian 1st and 2nd Edition but not Symbian 3rd Edition.

#include <e32std.h>
 
#define KPowerModeSettingNotifierUid 0x100059E2
 
void TurnBluetoothOnL() {
	TPckgBuf<TBool> pckg;
	RNotifier iNotifier;
	TPckgBuf<TBool> iNotifierResult;
	TRequestStatus status;
 
	User::LeaveIfError(iNotifier.Connect());
	iNotifier.StartNotifierAndGetResponse(status, KPowerModeSettingNotifierUid, pckg, iNotifierResult);
	User::WaitForRequest(status);
	User::LeaveIfError(status.Int());
 
	iNotifier.CancelNotifier(KPowerModeSettingNotifierUid);
	iNotifier.Close();
	User::LeaveIfError(iNotifierResult[0]);
}
 
void MainMethod() {
	TRAPD(err, TurnBluetoothOnL());
	if (err != KErrNone)
	{
		// Handle Error Here
	}
	// Bluetooth is already on
}
