The moving-map-app Sky-Map is able to receive external GPS-Data from an IP-adress and UPD-Port. Unfortunately I fail to get it working together with Xplane 10 with the given options (availlable choice of software products in the network/ipad-tab). While the log shows, that the ip-connection was established successfully, Sky-Map tells me that it receives invalid gps data. I would highly appreciate it!
