The capture device can be configured to follow a data connection between a specific Bluetooth Low Energy Master (Initiator) and Slave device. Type `a` in the options menu and write the address of the Initiator (Master) device. If this option is not setted, the capture device will start to follow the first data connection that appears on the selected advertising channel.
