Thread: Mutliple Dongles with Bluez
Mutliple Dongles with Bluez

    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.
