Hi all,
I am tracing bluetoothd in order to find why it is not working. Please
see strace output at bottom.
First I started DBUS:
# dbus-daemon --system --print-address
unix:path=/var/run/dbus/system_bus_socket,guid=bd671c01bf0366c80869f10000014a47
Then tried to start bluetoothd:
# bluetoothd -nd
bluetoothd[1795]: Bluetooth daemon
bluetoothd[1795]: Enabling debug information
bluetoothd[1795]: parsing main.conf
bluetoothd[1795]: offmode=NoScan
bluetoothd[1795]: discovto=0
bluetoothd[1795]: pageto=8192
bluetoothd[1795]: name=%h-%d
bluetoothd[1795]: class=0x000100
bluetoothd[1795]: inqmode=0
bluetoothd[1795]: Unable to get on D-Bus
It appears strange, bluetoothd can't get D-BUS, strace showed it is
not trying to open /var/run/dbus/system_bus_socket!
I am going to test older bluez version.
Please, can you suggest to me some idea to fix this issue?
Best Regards,
Alan
