Sonos controller for BlackBerry and Android

Why do I need to enter IP addresses ?

or, why can’t tiggit controller discover zone players like the Sonos controller ?

This is all down to UDP Ports. Ports are like channels that are used between computers on the network, with a known protocol that is used more information exchange between applications. For example mail tools use a known protocol on port 143, and web browsers users a known protocol on port 80.

Sonos uses a protocol known as Simple Service Discovery Protocol (SSDP) to discover the group of zone players that are related to your controller. There is a unique key per “household” which stops you discovering and controlling your neighbours zone players. SSDP uses port 1900 for discovery.

Sadly BlackBerry Smart Phones use port 1900 for something else: 1900 is used for the email attachment download. As a result it is not possible to run SSDP on a BlackBerry and participate in the SSDP protocol. There may be alternative ways to improve discovery, but for now I have drawn a blank on what would be the best route.
