[Bluez-devel] Mutliple Dongles with Bluez

[Bluez-devel] Mutliple Dongles with Bluez

[-- Attachment #1.1: Type: text/plain, Size: 512 bytes --]

Hello!

Anybody knows if its possible to interface multiple bluetooth dongles with Bluez? I would like to get pass the maximum 7 connections per dongle limitation of Bluetooth by installing more than one bluetooth dongle to a computer and thus increasing the number of connections available.

Anybody have experience developing such applications?

Thanks!

Regards
Shaun

you can do that. It simply works. There is a limit of 16 adapters per
host, but that can be changed with a simple recompilation of the
Bluetooth library.

This works fine, but make sure you have the latest Bluez libs. And make
sure you have a 
kernel at least 2.6.20 vintage. If not, then when you're running two
simultaneous commands to 
two different Bluetooth devices, you may get a kernel oops.
 
Otherwise, its easy enough to write a multi-threaded application that
addresses multiple dongles.
And it works very well.
