Detecting changing IP/network connection closed in serversocket

wl · Jan 16, 2012

Hello,

I'm running a server (on port 8080) in a service.

All is working fine: I can detected the IP my device is using (by calling GetMyIP after the Listen method).

But how can I detect my network connection is closed (possibly followed by another IP) ? Eg: when switching fro GPRS to Wifi (or vica versa) or just to detect when the networkconnection is down.

It seems neither the Stream_Error or Stream_Terminated is called

Thanks,

Wim

You can use PhoneEvents - ConnectivityChanged event to handle network changes.

Stream_Error and Stream_Terminated are raised when an error is detected in a socket connection (or the connection is closed).

If there are no current connections then you will not get any error.

Thanks Erel, helpful (as usual).

The description seems to be (see below). What are the possible values of NetworkType or State ? Is this listed somewhere ?

Thanks !

Phone.xml - version 1.71

PhoneEvents : Process object

Event
