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??..
