[Bluez-users] Problem with using HCI_UART driver

[mike]

Dear all
    I have a strange problem with using hciattach to a uart bluetooth 
device . I use a script to attach the device , but i need to attach two 
times to get the build ID.

hciconfig -a :
hci0:   Type: UART
        BD Address: 00:08:E0:01:49:6A ACL MTU: 192:8  SCO MTU: 64:8
        UP RUNNING PSCAN ISCAN
        RX bytes:189 acl:0 sco:0 events:21 errors:0
        TX bytes:351 acl:0 sco:0 commands:21 errors:0
        Features: 0xff 0xff 0x8b 0x78 0x18 0x18 0x00 0x80
        Packet type: DM1 DM3 DM5 DH1 DH3 DH5 HV1 HV2 HV3
        Link policy: RSWITCH HOLD SNIFF PARK
        Link mode: SLAVE ACCEPT
        Name: 'mike'
        Class: 0x000100
        Service Classes: Unspecified

0x490
        Manufacturer: Cambridge Silicon Radio (10)

script :
hciattach -s 921600 /dev/ttyS1 csr 921600 flow
hciattach -s 921600 /dev/ttyS1 csr 921600 flow

I have no idea what that is so, but I am not the expert in the UART
area. Maybe you have to change or add a sleep time to the CSR init
routine or switch the module to BCSP.
