Re: [Bluez-users] Device 'sleeping' and Reconnecting

[Chris MacDonald <chris@fourthandvine.com>]

Hello...

Me again, I've finally had a moment to play with this again so I have some logs that may help. I can still connect to the Apple bluetooth keyboard but the connection only lasts 30 minutes while idle then it disconnects...

...

Then when I hit a key...

Which looks like it's reconnecting, but I can never type again with the keyboard, each time I type it just looks like it's trying to reconnect again. It takes an "hidd --connect ..." to connect to the keyboard and type again. This is all taken with hcidump 1.3, I have more logs available.

I'm currently running Gentoo (2.6.19-gentoo-r5 from Portage) along with bluez-utils and bluez-libs 2.25 from Portage as well. Any help would be greatly appreciated, ideally I'd just like to have the keyboard reconnect and still be usable. I'm not sure if it's a simple directive I'm missing in my hcid.conf or something else along those lines. Speaking if which, here's my hcid.conf...

options {
        autoinit yes;
        security auto;
        pairing multi;
        pin_helper /usr/bin/bluepin;
}
device {
        name "BlueZ (%d)";
        class 0x100;
        iscan enable; pscan enable;
        lm accept;
        lp rswitch,hold,sniff,park;
        auth enable;
        encrypt enable;
}

Again, any help would be great, thanks.

Chris
