IP150 with firmware version < 4 connection stability about pai HOT 5 CLOSED

When socket times out USER LED turns OFF.

After many disconnects when I got lock up USER LED was ON and stayed ON after many minutes.

@jpbarraca Where did you get spec for IP module? Maybe there is a keep alive request? Or you did Struct from the tcpdump?

He got the dumps from my IP150 v4 and my friends v1.39.

Unfortunately he does not own a IP150 module

As always if anything is needed from my ip150 i can provide teamviewer for babyware to my ip150

We must poll the module constantly. Otherwise it will disconnect us. There was a bug related to the events: if wee kept receiving an event every second (e.g., zone open), the receiving logic (send_wait), would never stop handling events, and we would be disconnected.

I made some changes to try to avoid this in my last commits. Could this be related?

When connecting through STUN, the session needs to be refreshed every 10 minutes.
