[Bluez-devel] Multi-device : maximizing the number of concurrent ourgoing RFCOMM connections

["Olivier Le Pogam" <olepogam@free.fr>]

Hi,

I am currently working on trying to have the maximum concurrent RFCOMM 
connections (OBEX) from a PC with several dongles to mobile phones. I use 
several BT dongles, usually 4. From a bluetooth point of view, the device is 
always master and the mobile slave.

I have big difficulties to define which is the best solution (Hardware, 
Kernel, BlueZ version).

I have developped a simple forking application which is opening concurrent 
sockets to remote mobiles and I record the connection status (success, 
failure) and the connection delay, and I am running it on several 
configurations in order to get the best results.

I am really interested in contacting people having the same concern, or 
trying to find the best solution as well.

Here are some of my questions :
- Hardware
    . which BT dongles do you prefer (I use class 1 dongles, 2.0 EDR with 
USB2.0 support) ?
    . do you use a USB2.0 hub or direct connection to the PC USB ports ?
- OS / BlueZ
    . which Kernel version / distro and BlueZ version would you use ?

Everyone interested don't hesitate to contact me ( olepogam@free.fr ) so we 
can share our experience.

Best regards,
Oli
