OMTP (Open Mobile Terminal Platform), the mobile operator-sponsored organization, has released a set of requirements which provide a clear direction on the support of a consistent set of Bluetooth profiles for mobile devices and accessories.
OMTP notes that, as a technology, Bluetooth has evolved to support many types of functionality via profiles. Without a recommended design for mobile handsets, however, it is possible for many different designs to come market, resulting in products that do not communicate at all, or which have limited functionality.
To address this issue, the OMTP initiated a project with the objective of improving the end user experience for Bluetooth. Some of the worlds largest mobile operators, mobile manufacturers and chipset suppliers have been involved in the project. Recommendations have now been published and are available for public download here.
The recommendations support a number of scenarios, including the use of Bluetooth for connection with a headset; listening to stereo audio; in-car use; transferring files between a variety of devices; and wireless printing. The recommendations define two classes of Bluetooth which must be implemented on a mobile terminal with Bluetooth Core Specification Version 2 + EDR (Enhanced Data Rate).
Bluetooth is a key capability in mobile devices, but at present, it is not always clear which devices can connect to other devices or accessories for different wireless features, says OMTP Managing Director, Tim Raby. By introducing just a basic and advanced class of devices, consumers will avoid the situation where different Bluetooth devices cannot communicate because they support different profiles or revisions.
By simplifying the possible Bluetooth implementations used on mobile phones, OMTP believes that all areas of the value chain should gain – operators by simplifying their requirement specifications, mobile manufacturers by designing and testing against a single reference design, and consumers, who will benefit from improved connectivity and increased functionality. 
Following publication, OMTP says it will strengthen its working relationship with the Bluetooth Special Interest Group and other interested groups to ensure a wider adoption. In parallel, work will continue within OMTP to provide recommendations for future Bluetooth core specifications and associated profiles.
