iWRAP Bluetooth® Classic Software Stack

The iWRAP is an embedded Bluetooth stack for Bluegiga's Bluetooth classic modules. It exposes a powerful yet easy-to-use command interface to manage Bluetooth operations. It hides the complexity of the Bluetooth protocol stack and profiles from the end-user and can be used for almost anything; from simple data or audio applications to more complex use cases where interaction with several Bluetooth-enabled devices are needed - or even multi-profile environments for simultaneous audio and data connections.

The 6th generation iWRAP™ Bluetooth stack targets Bluegiga’s Bluetooth classic modules. It features both Apple iAP1 and iAP2 profiles supporting all Apple iOS devices on the market. iWRAP6 also adds the latest versions of Bluetooth audio profiles such as AVRCP v.1.5 with media browsing capabilities, MAP profile for SMS notifications and message download and new aptX® and AAC audio codecs for improved audio experience.
