[Bluez-users] MS Optical Desktop for bluetooth - Stops working after a time

[Bluez-users] MS Optical Desktop for bluetooth - Stops working after a time

[Daniel Scott]

Hello,

I am using the MS Optical Desktop for Bluetooth (to great success) on
Fedora Core 2, kernel . I do have a minor problem though.

The mouse and keyboard work fine. The problem is that after they are
left inactive for ~30 seconds, they seem to disconnect or 'power save'
and it takes a while for the connection to be re-established. Altering
the 'timeout' using something like:

hidd -t 10

does not help.

Any ideas?

Another minor problem is that I tend to leave my system running
constantly, after ~2 days, the mouse stops working and will not
restart, I have tried replacing the batteries, reconnecting the
devices and restarting the hci0 device (hciconfig hci0 down, hciconfig
hci0 up).

Would restarting hidd help, I cannot find a 'clean' way to shut it
down and I will try killing it and restarting it the next time that it
happens. The only solution that I currently have is a reboot.

Thanks for your time, as I said, they are only minor problems so,
don't worry about it too much.

Thanks,

Dan Scott

show us the output of "hciconfig -a".

In general the mouse should disconnect after 12 minutes and reconnect
when it is needed again.

OK, I will investigate this further and try to figure out what is
happening when the mouse stops working.

the correct settings for the link policy are missing. A Bluetooth mouse
or keyboard needs at least role switch and sniff mode to work correctly.

Hi, use this in your hcid.conf:

        lp rswitch,hold,sniff,park;
        security auto;
        pairing multi;

Re: [Bluez-users] MS Optical Desktop for bluetooth - Stops working after a time

[Paul Hedderly]

I have an Ericsson K700i. In the bluetooth menu there is an option
"remote control" and when you sdptool brose the phone you get:

Service Name: Mouse & Keyboard
Service Description: K700
Service Provider: Sony Ericsson
Service RecHandle: 0x1001c
Service Class ID List:
  "Human Interface Device" (0x1124)
Protocol Descriptor List:
  "L2CAP" (0x0100)
    PSM: 17
  "HIDP" (0x0011)
Language Base Attr List:
  code_ISO639: 0x656e
  encoding:    0x6a
  base_offset: 0x100
Profile Descriptor List:
  "Human Interface Device" (0x1124)
    Version: 0x0100

So I tried "hidd -c 00:..." with hidd --server runnning of course.

Now the phone wakes up and says "Start remote control? Yes/No" And I say
yes... it goes into remote control mode for a moment then quits saying
"No more files".

Anybody got their k700 to work as a mouse/keybd? What file is it
expecting?

Blues-utils/libs 2.9 (Debian/Sid) under 2.4.27-mh1.

I've dumped the exchange:

please do a "hcitool info <k700i>" as root for me and use the sdptest
program from the libs2 CVS repository to get me the full SDP records.

You don't need to install the libs2 stuff. Only check it out and compile
it with "./bootstrap && ./configure && make". After that you should call

	./test/sdptest records k700i-bdaddr > sdp_records.txt

and then send me the sdp_records.txt file. The output from "hcitool inq"
will also be nice to see what kind of class of device they are using.

>>From the hcidump I see a problem with connecting to the SDP PSM. It
seems that this is disabled when HID is in use and this phone has a
stupid L2CAP implementation that reacts weird and we do the same. But
for you it responds with "Connection refused - no resources available"
and this is great. They offer HID support and can't have three L2CAP
connections at the same time. That is totally stupid.

I need such a phone to tweak around the L2CAP problem and get the hidd
working without retrieving the SDP record. Any sponsor out there?

And btw do you enabled auth and encrypt in hcid.conf? Don't do so unless
you really wanna use security mode 3.

Regards

Marcel
