Yes it's inactivity of messaging between the central and peripheral.

Is the inactivity you mention inactivity of your messaging between the central and peripheral, or are you referring to 4 seconds of no connection events?

Update: OK, the BLE protocol keeps the connection up using connect events. As long as those are flowing, the connection will not time out. What I did in my application was to create an app timer to timeout my activity on the connection. If I do not get a message from my central application in X seconds I then execute the following call:

sd_ble_gap_disconnect(appBleData.connHandle, BLE_HCI_REMOTE_USER_TERMINATED_CONNECTION);

This will break the connection.

I restart the timer every time I receive one of my proprietary commands.
