Cheap Wireless for Accessories

Posted by michael on from the wires-are-so-last-century dept.

morcheeba writes "Yet another wireless protocol for personal computers! In addition to existing 802.11 variants, bluetooth, and ultra-low-power newcomer zigbee, Cypress semiconductor is releasing a simple low latency, low cost (<$2), medium speed (200kbit/sec) protocol with USB human interface devices (HID) compatibility. Partners include Saitek (game controllers) and NMB (keyboards & mice). EETimes has an informative article."

    I don't think so. Those mentioned protocols address different needs than Bluetooth. For example, Zigbee is targeted to those sensory applications that need to transfer data with a very low duty cycle. WirelessUSB tries to do what it's name suggests, replacing the cables in a USB connection. On the other hand, Bluetooth supports multiple transfer profiles. For many applications, it's serial profile excells as many developers are quite familiar with it and have used serial ports in PC or micros for years. Using it does not need you to write a complex software protocol stack like that of USB. You just get a sigle chip bluetooth solution, connect it to your micro's serial port and that's it!
