The SSDP (Simple Service Discovery Protocol) control module allows searching for UPnP devices in the network.
SSDP is a UDP-based protocol that allows UPnP devices to identify themselves in the network and communicate only the most important information. These include, for example, device name, device type, or a URL describing the device.
Further information can be found for example on Wikipedia
The SSDP Control is automatically installed as a core instance. This can be found in the object tree under core instances.
The module does not require any further configuration. By default it uses port 1900 to search for devices.
