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.

this must be hcitool -i hci1 scan.

Does using "hcitool inq" helps?
