[Bluez-users] bthid on ppc

[Bluez-users] bthid on ppc

[Ben Wilson]

Hi,
  I am trying to get the MS bluetooth mouse working with a
PowerBook with 2.6.3_rc2-benh kernel.

  I can get pan and bnep working, letting me access the internet
wireless! Awesome, even if it is only about 20k/sec, is that
normal?

  I also got rfcomm working, and can establish ppp connection
with my cellphone provider.

  The only thing that isn't working is bthid. It seems to die
silently when ever I establish the connection, or move the the
mouse. I still see events generated with hciconfig, but bthid
keeps exiting for no reason I can see.

Any advice? Anyone get this unholy trinity (Apple Laptop, MS
mouse, running Linux) working?

The mouse works fine with the MS dongle on x86.

Thanks!

actually I think the new SDP code and the HID program has some endian
bugs which causes your problem.

Does this mean this is a known issue? The HID program from
http://www.visi.com/~pmk/msbtkb-linux.html wouldn't even compile
for me, I figured it may be the same type of issue.

Are there any plans for making this work? I'm not a programmer,
but may be able to find someone to do it :)

Thanks!

Seeing this thread made me take up my old efforts to get my Apple
wireless mouse to work on my Debian-running iBook g4 (with built-in bt),
but it can't be the same type of issue since I did get Peter's bthid
mentioned above (same name, different program than in BlueZ cvs) to
compile (had to change some includes and so on) and work, it doesn't
crash but I could only use the mouse for a few seconds at a time, then
it would freeze for a few seconds, then work a few seconds, and so on
(and I mean full seconds, not figuratively speaking).
That was yesterday. Today I didn't even get that working, I managed to
move the cursor for just a short blink, maybe half a second or so.

That error could be in sdpd (that's what Peter's bthid's error messages
hint at, or so I interpret them) or in that bthid, or somewhere else, I
don't know.

So, anyway, it's not the same issue. BlueZ cvs bthid just dies silently
for me (even though the other tools, sdptool, hcitool etc works fine).

one love sunnan

the sdpd has nothing to do with it. It is the "new" SDP code that both
implementations carry and I think none of it is big endian safe.

Thanks for correcting my misinformation.
Could you please tell me where this suspected non-big-endian safe code 
is? (Which files and functions, etc?)

As I said, I've gotten the other bthid to work for repeating intervals a 
few seconds long. I guess it could still be a big endian problem, but it 
doesn't crash, it's just unable to read SDP (I don't even know what SDP 
is! Embarassing, I'm going to read up on that) sometimes.

I think the problems are in libs2/lib/sdp.c or libs2/lib/sdp_data.c.

There is a sdptest program under libs2/test and you can play with.
