Bluegiga Releases the Next Generation iWRAP5 Bluetooth Stack


Bluegiga announces today the availability of its next generation iWRAPTM Bluetooth 3.0 stack, iWRAP5 for Bluegiga’s Bluetooth Classic Modules. It adds new advanced features, such as iAP support for Apple accessory developers, Hands-Free Profile v.1.6 with Wide Band Speech codec, Continua 1.5 support for the Health Device Profile, as well as many other new features and improvements built to simplify Bluetooth connectivity and device management.

One of the major features in iWRAP5 is Apple iAP protocol support that allows developers to create Bluetooth-enabled accessories capable of interfacing to Apple iOS applications. For example, the iWRAP5’s iAP implementation includes features for automatic download and launch of an iOS application when the accessory connects via Bluetooth. iWRAP5 also provides a seamless transition from the iAP profile to Bluetooth SPP profile allowing accessory developers to create accessories that work with Apple iOS devices and devices that support the SPP profile, such as Android phones and tablets.

The iWRAP5 introduces several new audio features including Hands-Free Profile v.1.6 and Wide Bands Speech codec, also known as HD voice. The Wide Band Speech provides 16kHz bandwidth for Bluetooth hands-free connections significantly improving the audio quality and user experience for applications, such as Apple’s Siri voice recognition or Skype phone calls over Bluetooth. In addition, the iWRAP5 optionally includes CSR’s aptX® codec for enhancing stereo audio quality for A2DP applications and the fifth generation CVCTM noise reduction and echo cancellation algorithm for headset and hands-free applications.

The Bluegiga iWRAP5 Bluetooth stack offers Continua 1.5 support for the Health Device Profile, advanced Bluetooth HID profile support and more than twenty other new features and improvements for supporting Bluetooth device management and connection flexibility.

The iWRAPTM Bluetooth stack also supports twelve other Bluetooth profiles including: SPP, A2DP, AVRCP, MAP, PBAP, HFP, HID and OBEX, allowing accessory manufacturers to create truly versatile devices.
