Audio-specific Bluetooth WT32i reference design

WT32i is an audio-specific Bluetooth 3.0 module with excellent RF performance and enhanced audio capabilities for a first-class Bluetooth audio experience. In addition to the certified Bluetooth radio and software stack, the WT32i includes a DSP, stereo audio codec and battery charger, making it ideal for fixed and portable audio applications. The WT32i includes Bluegiga's iWRAP6 Bluetooth stack software that implements A2DP, AVRCP v.1.5 profiles and supports aptX® and AAC audio codecs for stereo audio applications. For hands-free applications, iWRAP6 software also supports HFP v.1.6, HSP, MAP and PBAP as well as CVC® echo cancellation software. For data communication with Android and iOS applications, iWRAP6 also implements Bluetooth Serial Port Profile (SPP) and Apple iAP profile. The WT32i is an ideal solution for developers who want to quickly integrate the latest Bluetooth audio technology without the time and cost typically involved in Bluetooth audio chipset design.

BLE113 development kit design information

BLE113 is a Bluetooth smart module targeting small, low-power sensors and accessories. It integrates all the functionality required for Bluetooth Smart applications, including Bluetooth radio, software stack and GATT-based profiles. The BLE113 Bluetooth Smart module can also host end-user applications, meaning no external microcontroller is required in devices with size or price constraints. The module features flexible hardware interfaces to connect different peripherals and sensors, and can be powered directly from a standard 3V coin cell or a pair of AAA batteries. In its lowest power sleep mode, it consumes only 500 nA and will wake up in a few hundred microseconds.
