WatchOS 2 and NSStreamEvent.ErrorOccurred

Question

I have an iPhone app that exchange data with a device over the LAN and send those to the WatchKit extension using the SendData method. All is working fine, but when the iPhone is suspended/sleeping I noticed that the NSStreamEvent.ErrorOccurred for the input stream is fired up with this message:

Error Domain=NSPOSIXErrorDomain Code=57 \"Socket is not connected"

It seems like the iPhone is losing its wifi connection. Do i suppose that when suspended the iPhone can't keep its socket connections opened?

Anyway be sure that you've configured your app to support back-grounding — deimus, Oct 19 '15 at 15:01
Back-grounding is enabled. And as suspended I mean both lock screen and black screen. — Nicola, Oct 20 '15 at 11:02
I've found the cause: iphone turn off (or something similar) wifi in suspend mode to save battery life. That's annoying that there is not a setting to keep wifi on everytime. — Nicola, Oct 21 '15 at 09:54

Well, at the end the problem is the WiFi connection of iphone 5, that when suspended or locked is dropped. I've found somewhere that this functional mode has been changed by Apple in iphone 6, so I should try with that.
