返信先: Adding new UPnP renderer to device list issue

[storaid]

Hello, Tiki

You are talking about SSDP protocol, and SSDP is using port 1900. So, I think 49152 and 49153 ports that you saying are client side port numbers. The port number on the client side changes with each session.

YES

When the TuneBrowser is running, if the service endpoint’s port on the iFi UPnP renderer changes during device startup, from 49152 to 49153, it will show as VOID on the device list.

Originally, the renderer would send a SSDP – NOTIFY to indicate that the LOCATION of the service endpoint is port 49152.

I suspect that during the device initialization, the service endpoint’s port changes to 49153 in some stage.

It’s possible that the TuneBrowser could make some improvements in this case?

For example, periodically detecting NOTIFY to check for changes, then updating the UPnP Renderer on the device list.

I am currently in touch with the iFi vendor to ask why the service endpoint’s port is changed during device startup.
