CAMBRIDGE, U.K. -- CSR (LSE: CSR.L) today announced that BlueCore4 has qualified to version 2.0 of the Bluetooth specification including Enhanced Data Rate (v2.0 + EDR). The Bluetooth SIG announced last week that Bluetooth v2.0 of the specification was finalised with EDR incorporated as part of the specification. BlueCore4-external EDR silicon is in production and available now.

Today's qualification of CSR's BlueCore4-external hardware and firmware means that CSR is now the only company to be offering fully qualified solution for v2.0 + EDR including all of the optional EDR features, to give higher speed data transfer and lower power consumption. CSR has always incorporated all of the optional features of the Bluetooth specification into its BlueCore Bluetooth products. Access to these optional features is an important consideration for designers when selecting Bluetooth silicon to implement in their products.

Bluetooth EDR offers maximum data transfer rates of 2.1 Megabits per second (Mbps) compared to the current 721 Kilobits per second (kbps) for standard rate Bluetooth. This increase in transfer rate also means that, for a given amount of data, the EDR radio will be active up to 3 times less than a standard v2.0 radio, hence reducing power consumption, which greatly benefits battery-dependent mobile devices.

Anders Edlund, Marketing director, Bluetooth SIG, commented, "The Bluetooth SIG has finalised Bluetooth v2.0 specification with EDR and we look forward to the range of new exciting products and applications this higher-data rate, lower-power version of Bluetooth will deliver. It is therefore encouraging to know that companies are keen to get v2.0 and EDR technology into products as quickly as possible. CSR's BlueCore4 hardware and firmware is one of the first solutions to qualify to Bluetooth v2.0 and EDR, and provide the foundation for product developers to start work on bringing these benefits to consumers".
