Subject: [Bluez-devel] hcidump with multiple dongles

Sorry, I forgot to mention that I'm running 2.6.20-1.2952 Fedora Core 6
with the latest Bluez libs and utils.
thanks,

Rich

Hello,

I've been working on a project that requires multiple Bluetooth dongles
on a single PC. I have a USB 2.0 hub with two dongles. I can create my
problem in the following manner:

- window 1 l2ping xx:xx:xx:xx:xx:xx - so this command is running
constantly.
- window 2 hcidump -i hci0 - this command is dumping
the output correctly.
- window 3 hcitool scan -i hci1
- window 4 hcidump -i hci1

After a little while ( sometimes immediately ) the hcitool scan in
window 3 will fail:

# hcitool scan -i hci1
Scanning...

Inquiry failed. Connection timed out.
#
#

The test works fine if I do NOT use hcidump. That is, I can run window 1
and 3 all day with no problem. When I add hcidump, the "hcitool scan -i
hci1" will then begin to fail to connect to the hci device.

Have you seen this ? Any fixes?

thank you.

Rich Williams
