For example, there are Hands-Free Profile (HFP) 1.5 implementations using both Bluetooth 2.0 and Bluetooth 1.2 core specifications. The way a device uses Bluetooth depends on its profile capabilities. The profiles provide standards that manufacturers follow to allow devices to use Bluetooth in the intended manner.
Used to set up and control speech and data calls between Bluetooth devices. The protocol is based on the ITU-T standard Q.931, with the provisions of Annex D applied, making only the minimum changes necessary for Bluetooth. TCS is used by the intercom (ICP) and cordless telephony (CTP) profiles. The telephone control protocol specification is ...
Most Bluetooth headsets implement both Hands-Free Profile and Headset Profile, because of the extra features in HFP for use with a mobile phone, such as last number redial, call waiting and voice dialing....which I guess answers that. (But all of these easily-confused TLAs and FLAs really do the Bluetooth ecosystem no favors.)
For example, when you use a mobile phone with a Bluetooth headset, the phone uses SDP to determine which Bluetooth profiles the headset can use (Headset Profile, Hands Free Profile (HFP), Advanced Audio Distribution Profile (A2DP) etc.) and the protocol multiplexer settings needed for the phone to connect to the headset using each of them.
A Bluetooth stack is software that is an implementation of the Bluetooth protocol stack.. Bluetooth stacks can be roughly divided into two distinct categories: . General-purpose implementations that are written with emphasis on feature-richness and flexibility, usually for desktop computers.
