@Prithviraj: We have experienced this issue lately. We are suspecting some changing with Windows caused the issue. The connection is not followed. Symptom is that you can capture all advertising packet, not just the one you selected.

The temporary work around is to unplug and plug the USB dongle , sometime it took 3-4 try to make it work again.

@Hung, I'm using PCA10028 as a sniffer to detect the connection between a PCA10028 based slave and a master of either PCA10028 or Android phone. When the advertisement happens the sniffer can pick it up, but the connection establishment and following the connected packets is not shown. I have selected the device from the list as you mentioned, but still it doesn't work. Is this an issue with PCA10028? Back in the days I've used the sniffer to follow connections with PCA10000.

@AbdelZ :

When not following any connection, the scanner can only scan for broadcast packets, which mean the advertising packet. Your Galaxy S5 doesn't broadcast.
When you want to follow a connection, you should select the device in the list first, by using up-down arrow buttons, or press the index number show on the screen. After that the scanner will scan for only that device's advertising packets, and will follow the connection when the phone trying to connect to the device. Note that you should start follow the device before it has established a connection.
