Hi All - does anyone have any info/documentation on how Philips implemented UPnP on Prontos? Or any pointers to general reference guides to UPnP?

I'm looking to build a separate Sonos module for the Pronto which will (at the least) allow integration of Sonos with Pronto for simple actions such as accessing line-in sources for zones/groups, and volume. I need this so I can start using my Sonos more as a multi-room, multi-source system, rather than a standalone multiroom music system.

I am new to UPnP but I'm OK with Javascript/Prontoscript so if I can get up to speed with UPnP I hope to crack this one. Once the base module is there can then consider additions (music queues, services, radio, etc). I want this to be a dedicated/optimised Pronto/Sonos module and not like the (unusably sluggish) Philips module.

Appreciate any UPnP help!

You can have a look at the UPNP library provided by Philips. I realize it is not the greatest but it is commented. This library should be installed as part of the Sonos module.

I often use RFCs or Wikipedia for specifications. I know Barry recently used Wikipedia for some things regarding UPnP.

Lyndel is correct. I did some research in order to develop my own upnp library. If you email me I will zip up the research and send it to you. I am not totally satisfied with the way the library is working so I am not giving it out at this time.

The problem I have is with testing as I have only one upnp device aside from the win 7 computer.

thanks both. Started with wiki and now got Intel Device Spy and Sniffer which have helped. Barry just emailed - appreciate anything you send.

I can't help you pthornhill but I've been thinking along the same lines myself.

If it were possible to just have basic transport commands and maybe even a current song/artist next in que display to be integrated into a multiroom control setup it would be better than nothing - which is effectively what we've got now.

So, if you have any success please keep us posted!


(actually, how ridiculous is it; that on a £1K remote - this is the best we can hope for usable control of Sonos - it's a joke)

The issue is not the Pronto, the issue is Sonos. To write what is neeeded on the Pronto requires detailed knowledge about how the Sonos operates from a communications standpoint. Please do not tell me they follow uPNP protocol; that like saying the use HDMI. Specifications and protocols are all subject to interpretations and version releases.

When I build an interface to a component be it Squeezebox server, Vudu, Sony changers, etc. I first read all I can about the interface. That itself is often monumentally frustrating. I then write the code (trial 1) and use something like wireshark or etherdetect to capture what is going on.

While "TCP/IP" is a guarnteed delivery protocol, (I will argue that when wifi is in the loop) anything over UDP is "Best effort", so an awful lot will depend on network traffic. As an example when I send out a "Magic Packet" to do WOL I send it about 20-40 times knowing that once the device I am addresing begins to wake up it will ignore all further magic packets.
