CSR NanoSira Reference Radio tests compatibility of Bluetooth devices with Windows XP

12/11/2002 - CSR (Cambridge Silicon Radio) announced that it is now supplying its NanoSira Reference Radio, a turnkey reference design of a USB dongle for easy testing of the compatibility of a Bluetooth device with Windows XP. The dongle incorporates CSR BlueCore, one of only two radios selected by Microsoft as a benchmark for Bluetooth testing before products can receive the Designed for Windows XP Logo. The product is available now from CSR's website (www.csr.com).

To demonstrate the compatibility of hardware with Windows XP, Microsoft has a process of certification called WHQL (Windows Hardware Qualification Labs). More information on WHQL is available at http://www.microsoft.com/hwdq/hwtest/

The NanoSira Reference Radio uses CSR's established v1.1 HCI Bluetooth Software stack and supports scatternet and 7 slave piconet operation. This hardware and firmware has been selected by Microsoft as a Bluetooth host controller (radio) for performing the WHQL hardware compatibility tests (HCT). This firmware is digitally signed by CSR to prevent unauthorised firmware upgrades. The design is compact with outside dimensions of only 50 x 20 x 5mm while maintaining +4dbm output power and -82dbm receive sensitivity using a printed antenna.
