Subject: [Bluez-devel] recursive locking on pairing: 2.6.18-rc4
Date: Tue, 22 Aug 2006 16:08:59 -0400 [thread overview]
Message-ID: <ecfo8s$790$1@sea.gmane.org> (raw)
I'm trying to pair my nokia 770 with my desktop which is
running fc6t2, kernel-2.6.18-rc4. bluez-libs-3.0. Using a
zonet usb dongle.
The 770 returns a "no services" message. On the desktop,
/var/log/messages:
