[Bluez-devel] hidp 2.4 backport

[Bluez-devel] hidp 2.4 backport

[Franck Arnaud]

Hello,

I have an epox (CSR) bluetooth mouse and I'm using kernel 2.4. I 
tried bthid 0.10, which worked fine initially but I could not make 
it handle reconnections (after a long enough timeout, clicking 
the mouse just after the disconnection message seems to 
reconnect OK). This looks like the problem described in the doc, 
although the solution (pinging the mouse to keep it awake) is 
not acceptable.

It would be a pain at this time to upgrade to 2.6 in my setup, so 
I backported the 2.6.6-mh1 hidp module to 2.4:

http://www.nenie.org/misc/bluetooth/bluez-hidp-backport-2.4-26.tar.gz

it may be broken as I don't know anything about kernel 
programming :-) but it seems to work fine, except it seems you 
need the -t timeout option on hidd, otherwise it fails like with 
bthid (I do not understand why).

It may not be worth applying to the official 2.4 patches as I 
guess most people can upgrade to 2.6 more easily than me.

nice work. Keep it up and I already changed some stuff in 2.6.6-mh2.

The hidd should set a default timeout of 30 minutes if you don't specify
any on the command line. Only if you set timeout to 0 it disables the
idle timer in the kernel module. Please check this on a 2.6 machine as
soon as possible.

Maybe if we are at HIDP version 0.8 or so. Right now it would be too
much overhead for me to maintain it.

Regards

Marcel
