I simply want to check the Bluetooth Status i.e. whether it is ON or OFF and accordingly take some action.

Can someone tell me how to do it as i am new to Bluetooth ?

U can use CSettingInfo to get the Bluetooth status. U can refer to the ProfileExample in the forum nokia.

Thnx , Actually i got it by using SOcketServer and RHost Resolver but that is an expensive method .
CSettingInfo one seems better atleast for the info it provides.

Have u ever used this class ? If yes just paste the code here and i wil take the help from it.

Code taken from ProfileExample in FN

iSettings = CSettingInfo::NewL(this);

// Order notifications when profile is changed
TInt err = iSettings->NotifyChanges(SettingInfo::EActiveProfile);
if(err != KErrNone)
{
// an error occured, show message to user
iView->ShowMessageL(KErrOrderingProfileChangeNotifies);

}
if(iProperties.bthPowerName)
delete iProperties.bthPowerName;
iProperties.bthPowerName = HBufC::NewL(32);
iProperties.bthPower = 0;

// SettingInfo::EBluetoothPowerMode == 100, so value
if( ReadPropertyIndex(SettingInfo::EBluetoothPowerMode,
EProfilesExamplePropertyBluetoothMode) == KErrNone)
{
// index was read successfully
switch(iProperties.bthPower)
{
case EProfilesExampleBluetoothSleeping:
case EProfilesExampleBluetoothPoweredUp:
iProperties.bthPowerName->Des().Copy(
(*iBthPowerModes) [iProperties.bthPower] );
break;
default: // unknown type
iProperties.bthPowerName->Des().Copy(
KProfilesExampleUnknownStringProperty);
break;
}
}

// form a double type list box item string
TBuf<32> bluetoothModeListItem;
bluetoothModeListItem.AppendFormat(
(*iPropertyListTemplate)
[EProfilesExamplePropertyBluetoothMode],
iProperties.bthPowerName);

// add to view's list box
iView->AddListBoxItemL(bluetoothModeListItem);

This worked for me on Nokia 3230 to detect Bluetooth power off state:
(Symbian 7.0s Series60_v21)

LIBRARY PlatformEnv.lib

#include <SettingInfo.h>
#include <aknnotewrappers.h>

CSettingInfo* settingInfo = CSettingInfo::NewL(NULL);
CleanupStack::PushL(settingInfo);

// Get current bluetooth power mode
// Possible values in release 2.0:
// 0 (unpowered/sleeping)
// 1 (powered up and fully functional)

TInt btMode;
TInt err = settingInfo->Get( SettingInfo::EBluetoothPowerMode, btMode );

if (err != KErrNone) {
_LIT(KSettingInfoError, "CSettingInfo returned error");
CAknErrorNote* note = new(ELeave)CAknErrorNote();
note->ExecuteLD(KSettingInfoError);
} else {
if (btMode == 0) { // (unpowered/sleeping)
// Do something to switch BT on,
// e.g. show notifier using KPowerModeSettingNotifierUid
}
}
CleanupStack::PopAndDestroy(settingInfo);
