Is SSDP protocol used every time we run an app?

[Ricardo Ruiz]

Hello,

I'm curious, is the discovery process used every time we run the iPhone/Android app to get the hub IP address?

I know the system uses SSDP (which is a UDP broadcast message.

If it is not used all the time, does this mean the apps save the last IP address and then try to connect to that IP address? What about if the hub has another IP? Should the HTTP network request fail in order to use the SSDP protocol again to discover the new IP address?

Thanks a lot for suggestions.
