Hi,
I am attempting to get Bluetooth working on an Android platform. I have got
things to the stage where a manual hciattach appears to work ok but an
attempt to start Bluetooth via the Android GUI fails and nothing much
appears to happen. Android version is 2.3.3. Kernal is 2.6.35.
I've had a look around the forums about this but everything seems to be set
up correctly. Can anyone suggest what the problem is?
Thanks,
Bruno
Here's the relevant bit of logcat after an attempt to turn Bluetooth on.
D/BluetoothService( 2084): Bluetooth state 10 -> 11
V/BluetoothEventRedirector( 2194): Received
android.bluetooth.adapter.action.STATE_CHANGED
I/bluedroid( 2084): Starting hciattach daemon
E/bluedroid( 2084): bt_enable: Timeout waiting for HCI device to come up

Here's the relevant piece from the init.rc file

Here's what I get when I do a manual hciattach. (Note I removed the -n
option in this case)
