Richardson, TX — (press release excerpt) — Cambridge Silicon Radio (CSR) today launched a ready-engineered example of a Bluetooth interface which emulates a normal serial port, thus eliminating the need for Bluetooth stack software. The fully specified design is based on CSR's BlueCore technology and Bluecore2-External chip.

While providing all the advantages of a wireless connection, the application of Bluetooth [in this manner] is transparent to the user. In appearance, the chip looks like a standard serial interface. The host device does not need to know that it is communicating over a Bluetooth link, there is no host processing overhead and the user is not required to write additional software or to purchase Bluetooth stack software.

The CSR BlueLab software development kit (SDK) is used to write software to run on the RISC processor inside Bluecore2-External. Using software supplied with BlueLab, the processor can simultaneously run the Bluetooth communications stack and Bluetooth Serial Port Profile. Crucially, for applications where a high data rate (greater than 100kbps) is not required, no additional host processor is needed. This reduces the overall cost of implementation (complete BOM) to less than $10.
