disconnect incoming ACL connection

disconnect incoming ACL connection

[卞磊]

Hi All,
    I'm debugging Qtopia bluetooth in my EVB, and found this issue:
    If it is a incoming HFP connection, after pressed "Disconnect
HFP", the Qtopia only release rfcomm device and disconnect rfcomm
connection, and the ACL incoming connection can't be
disconnected(check this by 'hcitool con'). Is this a bug or something
else? Thanks. And happy new year!
    My develop environment:
    kernel : 2.6.18.8 + some patches
    BlueZ : 3.26
    BT HW : STLC2500
    Headset : iTech

that has been fixed, but I can't remember in which kernel version. I
think your kernel is just too old.

Hi,
     I try it in kernel 2.6.27.2 (including bluez patch), but this
problem still exist. But when testing another headset, SonyEricsson,
this problem does not appear on both 2.6.18 and 2.6.27. So, i guess
it's not a issue of kernel. BTW, my BlueZ lib/utils is 3.26. Does it
cause this issue? Thanks.

Hi,

please _don't_ use top posting. I am considering to just ignore any kind
of top-posting emails.

it could be that we have some file descriptor leaks that caused it. I
would rather try bluez-4.27 since that is recent and not an old version
that is in maintenance mode.

Hi,
   I found the dbus interface of bluez-4.27 has been changed, so the
qtopia can't work against this bluez. Which is the lastest version
 that keep the old dbus interface? I think i can try it first. Thanks.
