Flow

The UPnP discovery and subscription flow is completely handled by peer-upnp, and follows the following strategy:

1. Issuing an M-Search request, asking for urn:schemas-upnp-org:device:MediaRenderer:1
2. UPnP-device says Hi
3. Requesting the UPnP-device defintion from the device (LOCATION of response) over HTTP
4. UPnP-device returns its defintion
5. Parsing the definition, looking for a urn:schemas-upnp-org:service:AVTransport:1 service
6. Sending a SUBSCRIBE request over HTTP to the eventSubURL of the AVTransport service
7. UPnP-device emits events to the advertised callback URL over HTTP
8. Parsing the events data and sending it over to Last.fm

Known issues

• upnp-scrobble uses scribble, which does not scrobble the album of your track. I have a patched fork available My patched fork of scribble is used.
• On a regular basis the UPnP-device does not send events. I am still investigating this very issue. Please use the subscriptionTimeoutInSeconds configuration parameter, which sould be decreased if you see missing notifications. This will result in a shorter timeout of the subscriptions, and a more frequent resubscription. peer-upnp discovers the optimal resubscription interval by looking up the timeout from the SUBSCRIBE response.
• I have tested the setup with Raumfeld One S, Netgear WNDR 3700, and a Raspberry PI 2 running Raspbian.
