Subject: [Bluez-devel] Suspend/resume issues with bluez
Date: Tue, 2 Mar 2004 22:02:19 -0500 [thread overview]
Message-ID: <200403022202.19259.mitsu@syntheticzero.com> (raw)
Hi, just thought I'd run this issue past you folks. I'm running the bluez
stack and utilities from Debian unstable on kernel 2.4.22-x1 (Xandros Desktop
2) on a Thinkpad T40p. It seems to run fine when I first boot; I am able to
discover other devices, they can discover me. I am a newbie trying to use
this protocol stack; so I haven't yet gotten any applications to work yet.
However, it seems to function, basically.
The problem is bluez never seems to work again after a suspend/resume. I have
tried shutting down the Bluetooth card (you can do with with Fn-F5 on a
Thinkpad) before suspending, as well as doing hciconfig hci0 down, and even
rmmod rfcomm, rmmod hci_usb (rmmod l2cap never seems to work) before
suspending, and then modprobe them back afterwards. Though my machine does
not hang or crash when coming back from suspend, the Bluetooth card never
works again. hciconfig -a prints nothing.
Interestingly, before I installed the bluez stack, whenever I hit Fn-F5 it
would freeze my machine. Now, it doesn't freeze it, but correctly toggles
the little LED saying Bluetooth is active/inactive. When bluez is working,
Fn-F5 makes hciconfig -a report the device there, then Fn-F5 again will make
hciconfig -a report nothing. But after a suspend/resume, Fn-F5 will *still*
toggle the Bluetooth LED, but hciconfig -a never shows a card.
Rebooting the system causes bluez to work again.
