CSR Bluetooth TrueWireless Stereo Development Kit

CSR (LSE: CSR) announced their TrueWireless Stereo software development kit for high-end Bluetooth stereo headphones and speakers. TrueWireless Stereo enables manufacturers to quickly bring high quality and innovative Bluetooth products for stereo headsets and speakers to market. The TrueWireless Stereo SDK is available now on the BlueCore5-Multimedia platform.

The development kit is based on the use of two Bluetooth devices, one as the master and the other as the slave. The call handling and control are supported on the master device which then relays the audio stream to the slave headset. This allows the product to work with any existing A2DP device already on the market. Audio is streamed from the audio source to the master unit and is relayed to the slave using CSR’s proprietary synchronisation protocol, resulting in truly wireless stereo sound to either a headset or speakers.
