Help in getting BlueZ version - 5.14 running please

Help in getting BlueZ version - 5.14 running please

[tony]

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)

Thank you for any suggestions or pointers in advance.

Thank you for the information.  Yes, my kernel is 3.2. I shall try blueZ 
4.101. Hopefully that wont have any dependency on the kernel version?

Thanks,
Tony
