Sony Vaio VPCS11V9E internal bluetooth adapter drops connection

[Lauri Kainulainen]

Binary package hint: bluez

Connection drops after a few minutes. Then after pressing a few keys, the connection goes up again. Mostly seems to happen when there is a short few second typing pause. This also drops other bluetooth devices, such as the Logitech bluetooth mouse, which need to reconnect.

Using 10.04 64bit.

dmesg is filled with these during every drop (here you see two connection drops):

Happy to produce more debug info if needed!

this also happens with the 2.6.34-kernel from the kernel-ppa

$ uname -a
Linux xxxx 2.6.34-020634rc7-generic #020634rc7 SMP Mon May 10 09:08:52 UTC 2010 x86_64 GNU/Linux

dmesg reports the same thing

[Lauri Kainulainen (luopio)]

Good news everyone! It's just a problem with the specific internal adapter my vaio is using. I got me an external A-link USB bluetooth adapter, which does not suffer from the same problem. Maybe it's a bug within the kernel module?

This is reported against an old version of Ubuntu and many things has changed since then. Because of that we won't fix this issue however if this behavior repeats on a modern version please fill a bug report against it and we will take it from there.
