title: Inquiry scan and bluetooth stack
body: <p>I'm trying to do something with this HCI module I got, which uses a CSR Bluecore6 chip. I'm very new to this, so I'd just want to make it perform inquiry scan only (i.e. make it discoverable). To do that, do I need to implement a bluetooth stack or do CSR chips already support that? The datasheet of the module isn't very helpful. Since it's a HCI module only, do I need to implement it inside an external MCU or within the chip?</p>
  
  <p>Any other advise on what to expect will be much appreciated!</p>
  
  <p>Thanks</p>
