Re: [Bluez-users] How to use Bluez with CSR chip ?

["colorant" <colorant@163.com>]

Hi henry

    Thanks for you reply.

    Yes , I am using BC4 A06 Rom version on an arm based embedded board.

    So this one must set pskey before running right ?

    I try to run the CSR's demo first to set the right pskey and run the 
chip up.
    After I exit the demo, I can use pc to detect the chip.

    While , then I use :

    hciattach /dev/ttyS1 bcsp 921600

    to attach ttyS1 to hci0

    after that , The PC can not detect the chip anymore.

    and then I try
    hciconfig hci0 up
    it can bring up the hci0 interface , but the pc still don't detect the 
chip.

    for kernel , I only insert bluetooth.ko and hci_uart.ko

    So , can you kindly figure out what might be wrong in my operation ?

    Seems to me the hciattach operation reset the chip. And I might need to 
modify the hciattach , or ?

Raymond
