Hi,
I have faced a small problem while trying to connect multiple PANUs via the=
same Bluetooth dongle. Actually the problem doesn't exist with all Bluetoo=
th dongles I have been using, since e.g. SCM Bluetooth Zio USB dongle can h=
andle multiple PAN connections without any problems.
But when I'm using e.g. MSI Bluetooth PC2PC USB dongle, the PAN connection =
to the first device is successfully established, but the second device can'=
t connect to it (although it has been found during the discovery procedure)=
. The attempt is just rejected, but I can't find any information regarding =
this attempt from /var/log/messages file or output of hcidump.
I'm having exactly the same settings and configurations with both dongles, =
so I would guess that the problem must be dongle-specific.=20
This is the output of 'hciconfig -a' command while using the SCM's dongle:
hci0:=09Type: USB=20

And this is the output of 'hciconfig -a' command while using the MSI's dong=
le:

The only difference I can spot here is the HCI Revision and LMP Subversion =
fields, but can these explain the different performance of the dongles? Or =
is the reason somewhere else? At least it shouldn't be in any way related t=
o the PAN profile, since the problems seem to exist in much lower level of =
Bluetooth.

Hi Sami,

At least it shouldn't be in any way related to the PAN profile, since the problems seem to exist in much lower level of Bluetooth.
the problem can be CSR firmwares prior HCI 16.4 and take a look at my
web pages to see how HCI revision fits in to the CSR firmware version.

Marcel
