[Bluez-devel] Bluetooth HID device doesn't work (HID create error)

[Bluez-devel] Bluetooth HID device doesn't work (HID create error)

[Michal Krenek]

Hello,
I have Sony Ericsson K700 mobile phone, which supports standard HID profile=
 (you
can use it as remote control for your computer). I have tried this function=
 in
november (or december) last year and it had worked without problems. But wh=
en I
tried it today, it doesn't work. My mobile phone freezes on "Connecting" an=
d I
must restart it.

I have kernel 2.6.16.4, udev 089, bluez-libs & bluez-utils 2.25. My phone i=
s
paired with my PC and every other bluetooth functions work without problems
(file transfer, addressbook synchronization, internet connection via GPRS,
etc.). hidp kernel module is loaded and hidd --server is running (as root).=
 This
is what hcid and hidd gives me when I try it:

hcid[2620]: link_key_request (sba=3D00:13:85:00:0E:62, dba=3D00:12:EE:7D:03=
:CF)
hidd[2634]: HID create error 2 (No such file or directory)

I have tried also strace on hidd:

open("/usr/var/lib/bluetooth/00:13:85:00:0E:62/hidd", O_RDONLY) =3D -1 ENOE=
NT (No
such file or directory)

Well, this file really doesn't exist, so I have tried to create it manually
(touch /usr/var/lib/bluetooth/00:13:85:00:0E:62/hidd) and then repeat it. I=
 have
also checked write permissions and it looks good. Now hidd gives me this er=
ror:

hidd[3846]: HID create error 22 (Invalid argument)

And if I try strace it:
open("/usr/var/lib/bluetooth/00:13:85:00:0E:62/hidd", O_RDONLY) =3D 9
flock(9, LOCK_SH)                       =3D 0
fstat64(9, {st_mode=3DS_IFREG|0644, st_size=3D0, ...}) =3D 0
mmap2(NULL, 0, PROT_READ, MAP_SHARED, 9, 0) =3D -1 EINVAL (Invalid argument=
)

I am really lost now, I don't know where is the problem. Can you please hel=
p me?

Thanks,
Michal Krenek (Mikos)

use "hidd --search" to connect to your phone. You need to do this at
least once to have the correct data in the hidd file.

Unfortunately this doesn't work. I have tried to kill running hidd --server=
=20
and then run hidd --search but without success=20
(file /usr/var/lib/bluetooth/00:13:85:00:0E:62/hidd is still missing). Then=
 I=20
tried to run hidd --search and while hidd --search was running, I have trie=
d=20
to activate "Remote control" function on my mobile phone, but also without=
=20
success (mobile phone doesn't freeze, but "connecting" phase is terminated=
=20
with "Can't connect to remote device" and hidd --search still didn't find=
=20
anything).

Also in the past (as I said in november or december) it has worked without=
=20
problems out of the box (I didn't have to run hidd --search). So I think th=
is=20
is some problem with newer versions of bluez-libs, bluez-utils or kernel.
