Hi,
I am trying to familiarize with blueZ commands. I can scan
devices and see HCI commands and events using hcidump. But am having
some problems which I have been trying to figure out the past two days.
Any suggestions or pointers will be much appreciated.
1) I found a lot of forums talking about creating connection. But
couldn't find any which says how to accept connection. I am trying to
accept an A2DP connection. The peer device is sending an AVDTP Connect
request but don't know how to make blueZ respond. Can somebody please help?
2) I tried to start bluetooth daemon by running
../src/bluetoothd -n -d
bluetoothd[4440]: Bluetooth daemon 5.14
bluetoothd[4440]: Failed to access management interface
bluetoothd[4440]: Adapter handling initialization failed
The kernel modules I have are
lsmod | grep blue
bluetooth 158447 7 rfcomm,bnep,btusb
Should I be running any other command before bluetoothd?
3) I am get problem in getting the python scripts in the test folder.
For example when I try to run simple-agent it throws up dbus error as
below. I tried googling from which I understand some people had the same
error with 5.13 as well. The dbus version I have is 1.6.4 (I had to
upgrade from 1.4 to build blueZ)
./simple-agent hci0 00:1B:DC:07:2E:95
Traceback (most recent call last):
File "./simple-agent", line 158, in <module>
obj = bus.get_object(BUS_NAME, "/org/bluez");
File "/usr/lib/python2.7/dist-packages/dbus/bus.py", line 241, in get_object
follow_name_owner_changes=follow_name_owner_changes)
File "/usr/lib/python2.7/dist-packages/dbus/proxies.py", line 248, in __init__
self._named_service = conn.activate_name_owner(bus_name)
File "/usr/lib/python2.7/dist-packages/dbus/bus.py", line 180, in activate_name_owner
self.start_service_by_name(bus_name)
File "/usr/lib/python2.7/dist-packages/dbus/bus.py", line 278, in start_service_by_name
'su', (bus_name, flags)))
File "/usr/lib/python2.7/dist-packages/dbus/connection.py", line 651, in call_blocking
message, timeout)
dbus.exceptions.DBusException: org.freedesktop.DBus.Error.Spawn.ChildExited: Launch helper exited with unknown return code 1
Thank you for any suggestions or pointers in advance.
Tony
