Intent Error

Hi I have an error with this code

Sub Activity_Resume
Intent1.Initialize("android.bluetooth.device.action.FOUND" , "")
Intent1.PutExtra("android.bluetooth.device.extra.RSSI",Null)
StartActivity(Intent1)
End Sub

Error
android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.bluetooth.device.action.FOUND flg=0x20000 }

I am trying to find if a Bluetooth Device is connected via the Signal strength
Can any body help. Please.
