I turned off the WiFi
on my netbook and tried the UDP sharing, and it would not work. If I turn on the WiFi, it starts to work as soon as the DHCP server assigns an IP address. And then when I turn off WiFi again, the NMEA
stream on UDP immediately stops. It's like the machine loses its IP address assignment as soon as it leaves the network.
I ran the same test on wired ethernet and got the same results. As soon as I disconnect the ethernet cable, the UDP communication stops.
So I tried assigning a static IP address to the wired ethernet port, and got the same results. Even if static IP is assigned, the UDP appears to need a running network to function.
I just realized that these tests were done on 3.2.2. I will have to re-run the same tests on 3.3.1117 to see if there is a different result.
