The ComSonics pairing app is used to wirelessly connect the ComSonics QAM Sniffer-III and the ComSonics GQS-III devices together via Bluetooth.
Once the devices are paired with each other, the application does not need to be run again as the two devices will automatically pair whenever they are within BT range of each other.
The pairing app can also be used to unpair the devices when desired. This is typically done when one of the two paired devices is replaced with another device.
