AIS not displaying Data

Stuart

Hi All,

I love my AngelNav app. I’d like to display my AIS data however. I have an Emtrak WiFi broadcasting AIS which shows all relevant data on my Navionics app, but not on AngelNav. I THINK I have followed the instructions correctly, and I have the AngelNav AIS subscription ~ I have tried both signal K and NMEA in the settings and neither seem to work, although on the NMEA setting there seems to be additional inputs required which are beyond my understanding… I have attached. Screenshot showing the NMEA selection and the Signal K configuration - which indicates a default demo server address.

Can anyone shed some light on this for me please?

Hi Stuart,

I'm sorry that it's not working! It looks like you have AngelNav set up for SignalK, and I am not sure whether the Emtrak unit supports that.

Please can you send a screen shot of your settings in the Navionics app? That will help us get the correct settings for AngelNav.

Best wishes,

Bill Aylward

Hi Stuart,

Sorry - missed the second screen shot and I see you have also tried NMEA. There are three crucial settings for this:

The protocol (which probably should be TCP)
The Host - this is the IP address of the Emtrak
The port - this needs to match that used by the Emtrak

The values you need will be found either in the Emtrak manual, or in the settings for Navionics (since this is working they must be correct there), or on the internet.

I am not sure exactly what model you have, but I found this article which suggests the following:

Protocol: TCP
IP address: 192.168.2.1
IP port: 5000

Try putting these into Settings, the slide the Connected button to on. If it's working you will see the GPS and AIS activity lights flashing.

Best wishes,

Hey, apologies if I should start another thread but I have today setup the Yakker device to put ais nmea and seatalk1 onto wifi.

The yakker can operate in both udp and tcp modes. I have tried both in angel nav and both drive the instruments.

I left as tcp and applied the ais purchase and vessel data is also displayed.

I also use boatbeacon that has many uses but a useful one amongst many it can consume internet provided ais data and combine with a local ais received data and retransmit as combined internet and local ais data streams. This

How could I set up AngelNav to receive instrument data from yakker (has its own ip address) and ais data from the boat beacon (has its own ip address). Note both these addresses are in the same network. Boatbeacon just runs as an iOS app (I think android too) and I have all these apps installed on my iPad and iPhone

Thanks in advance.

That's an interesting question, and I don't have an immediate answer as I am not familiar with BoatBeacon. I presume that you have it set up to read data from the Yakker (as the source of local AIS data) and it then combines that with internet derived AIS data into a single feed?

I gather from the website that you can make an in-app purchase within BoatBeacon to allow 'AIS sharing' which then re-transmits the combined data for reading by another app (eg Navionics). It sounds like you may already have this, and it should work with AngelNav too by pointing the latter to BoatBeacon's IP address instead of the Yakker.

The open question is whether the code in BoatBeacon also sends instrument data. AIS messages are just plain old NMEA 0183 messages with coded content, so if BoatBeacon is relaying the AIS messages, then it may also relay the others too (In fact from a coding point of view they would have to positively write code to NOT do this!).

So my suggestion is to try connecting AngelNav to BoatBeacon and see what happens. If you only get the AIS data, then it means that they are indeed filtering out the instrument messages.

At the present time, AngelNav can only connect to a single source of NMEA data, though this could be added as a software enhancement at a later date.

Let us know how you get on!

Hey Bill, Boatbeacon only passes AIS, I have communications with the author from sometime last year so I’ll pick it up with him.

There is another weirdness I noticed. When AngelNav is set to use NMEA source (for me yakker), the Centre on boat is greyed out and the boat position is not displayed. On location services, boat is displayed and the center on boat button works.

Hi Jonathan,

That suggests that there is no GPS information in the NMEA feed from the Yakker. Please could you send me a sample?

Go to Settings: Navigation Data and turn on 'Show Console'. Wait about 20 seconds for a good number of messages to appear, and then tap 'Email messages'. You then have to paste them into the email that appears and send it.

Best wishes,

Bill
