Yes, empty packets are sent over the physical link (no payload). You can see them easily as a pair of packets every CI on the TI packet sniffer, when the link is quiescent.

I'm having a hard time getting precise information about BLE connections.
Specifically, I want to know if there's no data to transmit, does BLE maintain the connection by continuing to send packets over the physical link? It seems this would be necessary, otherwise the supervision timeout would result in the connection being closed, but my app does not seem to drop the connection, even though no characteristics are being written.
Can anyone elaborate? Thanks.
