Software stack for Bluetooth audio accessories

14 October 2015 Telecoms, Datacoms, Wireless, IoT

Silicon Labs introduced a sixth-generation version of the iWRAP Bluetooth software stack for the Bluetooth 3.0 wireless audio accessory market. iWRAP 6.1 software is a full-featured embedded Bluetooth stack from Bluegiga, a Silicon Labs company, designed to support the popular WT32i Bluetooth audio module. Target applications include smartphone accessories, stereo and hands-free audio, cable replacement and Bluetooth HID.

The software stack exposes a powerful yet easy-to-use command interface enabling developers to manage Bluetooth operations. It hides the complexity of the Bluetooth protocol stack and profiles for a wide range of applications, from simple audio and data applications to more complex use cases requiring interaction with several Bluetooth-enabled devices, or even for multi-profile environments with simultaneous audio and data connections.

iWRAP is supported by Silicon Labs’ easy-to-use BGScript scripting language. Embedded into each Bluetooth module from Bluegiga, BGScript eliminates the added cost and complexity of using an external host microcontroller and separate software development kit (SDK) required by conventional Bluetooth development alternatives.

No Bluetooth wireless development skills or tools are needed to use the iWRAP stack, and the software’s simple ASCII-based command and response API over UART is easy to use and learn. It supports up to seven simultaneous connections with data throughput up to 500 Kbps, and is customisable and field-upgradable over UART.

The software supports 13 integrated profiles for data and audio applications including the Apple iAP1 and iAP2 profiles, supporting all Apple iOS devices on the market. iWRAP also adds the latest versions of Bluetooth audio profiles such as AVRCP v.1.5 with media browsing capabilities, a MAP profile for SMS notifications and message downloads, and new aptX and AAC audio codecs for an enhanced Bluetooth audio experience.

iWRAP 6.1 supports the following new features:

• Audio tone support – audio tones (files) can be stored on the Bluetooth module’s Flash memory, with playback support for stored files.

• Audio tone mixing – audio tones can be mixed with A2DP or HFP audio output.

• Simultaneous AVRCP controller and target profiles – improved user experience with the latest smartphones.

• Enhanced user-configurable Bluetooth reconnection logic.

• Software application programming interfaces (APIs) added for the I²C interface.
