Yes, that is off.
Quote:Another thing to realize is MacENC is running non stop, but each time iNavX is started you need to give it some time to receive all the AIS target info..
Understood - but this was occuring even after iNavX had been on a while - or so it seems. I'll do more investigation next time we're out.
I plan to have my nmea->wifi box cache the AIS info and the moment a new tcp connection arrives (when the iPad is switch on), I'll send down all the AIS information immediately - to improve things. I'll start with just the static info (type 5 and type 24 messages I guess). No reason why this couldn't be extended to the latest position reports for each target (given appropriate expiry mechanisms in the cache of course).
Quote:With iOS 4.2 (November release) this will be less of an issue because apps won't be exited, but only suspended.
Does that mean the iNavX application will maintain the tcp connection when I switch to another app? What about if the iPad is switched off?
