Hi Jeff,

What is your reason for saying: "Latency and tuning" of the N210 device
isn't appropriate???

I should have said that, with either USB or Ethernet, and with a non-real-time O/S, the latency to too great. Hop rate is generally 1600 hops/sec. Take a look at the Bluetooth physical layer spec for more info.


Best,
Mostafa

        Hi All,

    You could build one in the FPGA of an X-series box. Latency and
    tuning requirements exceed what you can do with a N210.

        <http://gr-bluetooth.sourceforge.net/>), However it is not a
        complete stack and I guess it doesent include the Bluetooth
        Transmitter.
        I built it and checked but couldn't find one. Can you suggest any
        existing implementation of complete Bluetooth stack ?
        Any Help is appreciated.
