Could not connect to Bluetooth device through the serial port
I want to establish ppp communication through serial connected Bluetooth modem (Ezurio, CSR chipset BC04).
When I use minicom terminal, it works OK, I configure it to the minimum (9600) speed without flow control and can send AT commands, can scan the bluetooth environment, find other bluetooth devices, etc.
When I want to use BlueZ drivers stack of Linux (2.6.12 I use), I fail on first command:
hciattach /dev/ttyS0 socket.
Socket should be bcsp, as I understand, but I fail on "initialization timed out".
If I use "non-specified" UART socket (option socket="any"), it "succeeded", but in hciconfig I see zeros in address and cannot turn the device up, i.e. it doesn't work.
May be someone already faced similar problem?
What should I do in addition to above, before trying to attach this serial device?
