Excellent app and fast support!!

I have a basic raymarine seatalk ng system on a sailboat. It includes a p70/ACU-200/EV-1 autopilot, wireless wind (T120 and T112), micro-talk gateway, Axiom 7 MFD, and YDWG. Not only can I see wind, gps, and rudder reference data in this app, but I can also control the autopilot!! It took only a few minutes to setup and even though I had the settings incorrect on my first go, Scott Bender’s advice fixed it right away. Definitely reach out before giving up!

Great App - but can you use to local iPhone GPS?

Really great App. Easy to connect, reliable, everything great but I don’t have a GPS on my boat so I’d like to use the iPhone GPS directly or connecting to a GPS server app such as GPS2IP. Is this configuration supported?

Wind Data not available

I purchased the app to use and monitor wind data [among other data points], but the app does not parse $WIMWD nor $SDMDA messages. I have a fairly new Simrad system (only 7yrs old) and these are the messages I need to view/monitor. I tried using OpenCPN and they are parsed correctly by that application. Please add functionality for this in your app. I emailed the developer and provided all necessary log and message data. I am still waiting on a response.
