hy all,
I am doing a project, which requires 'n' simultanious connection,
depending on the users loggin into the facility. I was thinking about
implementing an application level "scheduling" to take care of
multiplexing the request. But is there a limit in bluez?? I have heard
bluethooth has a 6slave+1master rule?? I read the FAQ for bluez..but
it confused me with saying .. "multiple devices can be connected".
thanks for your time,
joel.

yup now i got what you were trying to say. So effectively. i can
connect 7 mobiles through bluetooth to my laptop adapter at one
instance of time. hmmm... I read a spec.. It says while its true only
7 can form a piconet, we can have 255 connections put on hold( passive
mode).. i think i can manage from here... thanks a lot.
joel.

You should read the specs a bit.
A dongle is a physical device that you plug to your computer via
different medias like USB, RS232 etc.
Each one of those dongles can manage up to 7 connections, and bluez can
handle up to 15 of those dongles.
Cell phones can handle up to 7 ACL connections (low level), higher
levels connections depends on the cell.

oh here i got a little confused,
7 connection for each dongle you mean??.. that means i can connect 15
different BT devices and each device can simultaneously have 7
connections with the Bluez stack??.. My application works on a
topology with heterogenious BT devices. Mobiles being the lowest
common denominator. So when i talk specifically about mobiles, I can
connect 15 mobiles to Bluez with one connection from each(i think
mobiles cant have more than one connection at any instance of time).
If i can get these informations cleared up first, i can continue with
my interesting venture ;). I am planning to circumvent this
restriction using multiplexing. I will just let the connections wait,
till they get free ;). Let me see how it goes. But someone please
correct if i am still misunderstanding the BT constraints.
joel.

Joel,
You have 2 maximuns one is because of bluetooth specs the other is
because of BlueZ constraints.
BlueZ can handle up to 15 (someone correct me if I'm wrong) bluetooth
dongles (hci devices).
Then you can get up to 7 connections per bluetooth dongles (bluetooth
constraint)
Cheers,
Manuel
