Classic Bluetooth® Roleless Connection
When configuring the ComProbe BPA 600 devices for a Classic Bluetooth connection it is no longer necessary to assign a “Master” or “Slave” role to each of the devices. All Classic connection are “roleless”. For example, suppose you have a phone and a speaker as shown below:

Should the roles change during the connection the arrow will change to show the new "Master/Slave" connection. In the following screen shot the speaker has connected as the “Master” to the phone as the “Slave”.
