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:

It does not matter which position you enter the device. After you have started sniffing and a connection is made, the arrow will indicate the direction of the connection. In the following screen shot the phone has connected as the “Master” to the speaker as the “Slave”.

Roleless connection will detect the Master and Slave

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”.
