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
