[Bluez-devel] Combinations of multiple BT dongles, master/slave role change

[Jeremy Goodwill <skatewalking@gmail.com>]

Hi all,

Pls bear with me if I have missed out some fundamentals of Bluez/Bluetooth.

My question is:

Using following topology

Machine (with Bluez stack) connected to 2 USB dongles:
-dongle A
-dongle B

The following procedure is performed:
1) dongle A connects to device C
2) role switch of dongle A to master
3) connection becomes active
4) dongle B connects to device D
5) role switch of dongle B to master
6) connection becomes active

At this point, will channel collision occur?  Is Bluez aware of the different
channels that each connected dongle is using and therefore avoid using the same
ones? 

Thanks in advance,
Jer
