hi all I got a problem while init the csr bluecore4 chip, my toolchain: bluez-3.12, dbus-1.0.2,kernel-2.6.10 #dbus-daemon --system #hciattach ttyS0 bcsp #hcid -f /opt/bluez/etc/bluetooth/hcid.conf #hciconfig hci0: Type: UART BD Address: 00:02:5B:00:A5:A5 ACL MTU: 310:10 SCO MTU: 64:8 UP RUNNING PSCAN ISCAN RX bytes:1128 acl:0 sco:0 events:23 errors:0 TX bytes:706 acl:0 sco:0 commands:26 errors:0 above is always ok. but csr chip need to set pskeys and warmreset,so I run bccmd #bccmd warmreset #hcitool scan Scanning Timeout... This problem around me for a few days, I cant figure out why the csr chip doesnt work after warmreset.UART0 connect to csr chip, so I choose bcsp config in kernel and choose hci interface(here i am not sure about choosing hci or bcsp while run bccmd?), am i right? -- Best Regards ------------ Tony
