No, there's no API in GUPnP. What I did in Helium is to disable/enable
the control point but that has the drawback of getting
device_unavailable signals. [1]
I wonder if it would be possible/sensible to add a new method to GSSDP
that allows clients to force a rescan without clearing the cache. This
should prevent the device unavailable signals while allowing new devices
to be discovered. On the downside, it would not clear out old devices
which have disappeared from the network but are still present in the
GSSDP cache, so it wouldn't be a perfect solution. If you think this
might be a sensible thing to do I can enter a bug for this.

Mark

Why wouldn't it? I think there are two strategies to handle this:
1) Remove devices that don't answer after rescan immediately
2) Handle those devices via normal timeout mechanism as they didn't send
BYEBYE apparently.
Please file a bug, I like the rescanning.

Great.
