Cambridge Silicon Radio (CSR) and Cypress Semiconductor have jointly developed a less-than-$15 (total BOM) Bluetooth solution for off-the-shelf USB-enabled peripherals. CSR's USB Bluetooth printer dongle design brings together its BlueCore Bluetooth chipset and Cypress's USB On-The-Go (OTG) semiconductor technology.
The printer dongle design allows standard USB-enabled printers to receive and print Bluetooth data from laptops -- or eventually PDAs, digital cameras or mobile phones -- without turning on the printer's host PC. According to CSR and Cypress in future the design will be applied to other USB peripherals, such as storage devices, web cams and audio speakers, creating a range of host-free wireless connections between Bluetooth and USB devices.
The new dongle plugs into standard USB printer ports, and the technology may eventually be integrated into printer designs. Cypress's EZ-Host USB controller inside the dongle acts as "host," mediating data "traffic" between the portable device and printer.
CSR is already providing samples of its complete example design to several manufacturers worldwide, and is expecting volume quantities of products featuring the technology to be available in Q4 this year. Its Bluetooth printer dongle example design is available now from CSR design
