Re: [Bluez-users] how many BT devices can be connected at the same time?

[Manuel Naranjo <manuel@aircable.net>]

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.
