SIMULATION OF DEVICE REMOVAL

Abstract:

In one aspect, a computing device is configured to, while operating as a control device of a networked media playback system that includes a first set of network devices and a second set of network devices, (i) transmit a first message to each network device in the first set of network devices, wherein the first message comprises a command to, at a first time, temporarily disconnect from the computing device via a particular communication protocol, (ii) transmit a second message to each network device in the second set of network devices, wherein the second message comprises a command for the network device in the second set of network devices to, at a second time, test connectivity with the computing device; and (iii) after the second time, determine whether each network device in the second set of network devices was connected to the computing device.
