hi raymond the csr bc4 need to be configured before real running, some pskey should be set and warmreset should be issued. 1. add --enable-bccmd feature while configure the bluez-utils 2. use bccmd after hci0 is up: $bccmd -t hci psload -r /csr.psr here csr.psr is the pskey config file, -r means warmreset after pskey configured,there is a example psr file in bluez-utils/tools/example after that, u can see the other device through hcitool scan attaboyu ÔÚ2008-06-11£¬colorant дµÀ£º >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.
