I must have goofed somewhere, not sure where.

What does "uname -m" return, compared to what's boldened above?

Trying to install YAAC on a Raspberry Pi for my RV, followed website instructions and get the following error:

michael@trailer-pi:~/YAAC $ java -jar YAAC.jar
Error occurred during initialization of VM
Server VM is only supported on ARMv7+ VFP

I must have goofed somewhere, not sure where.

I installed the required stuff with

sudo apt-get install openjdk-11-jre unzip libjssc-java

and it looks like everything went OK.

I copied the Desktop file from another machine that is working OK, but the program won't launch from the desktop icon. I tried from the command line and get the above error.

Researching I found others who had similar issues and was suggested to try

sudo apt install default-jdk

Which went OK, but then

/YAAC $ java -version
Error occurred during initialization of VM
Server VM is only supported on ARMv7+ VFP



After a lot of fooling around, I figured out I was using an old RPi B+ with an ARM6 processor, which normally doesn't run Openjdk 11. However, I found this website with a version for older processors.



It seems to be really slow, but it is finally running.

"Any day you do not learn one new thing is a wasted day."

Most likely Option 2. As I-gates go, YAAC is very slow, because its prime focus is to get the information on the screen for use by the human operator. So, if any other (non-YAAC) I-gate heard the same signal, it will probably get it to the APRS-IS backbone faster, and the backbone discards duplicates coming in from other I-gates.

If you want to test your I-gate with aprs.fi, it has to I-gate a signal that no other I-gate could hear (say, an HT on minimum transmit power using rubber duck antenna or worse that is next to your I-gate's receive antenna).

Also, ensure your own I-gate's beacons are making it to the Internet directly from your own Internet connection. That confirms your Internet link is working.

Hope that helps.

Option 2.

I have my station setup to "Allow RF -> IS gating" and I have ports setup for both RF and IP, and both have Transmit Enabled. Looking at the Raw Packet sniffer with the filter set to packets from the KISS-over-TCP port (which is RF right?) I can see that I've been hearing stations. But if I go to APRS.fi and look at my station, it doesn't list anything under the "Stations heard directly by..." section. Does this mean my iGating is not working, or just that the sending stations are getting into the server via another means? Directly to the internet or via a different iGate?

Sounds like you're running a very ancient build of YAAC. That provider API version dates back to mid-2021; are you at build#165? The current build is #191. I recommend you upgrade to get the hundreds of fixes and enhancements I've put in since build#165.

Thanks for the quick reply! I will see if the decoder works... But I have a new problem installing the plugin, look below....

Yes. You need to install the AISdecoder plugin for YAAC. It will interpret the DireWolf messages you described below, and map the vessel information into objects (similar to APRS stations) like the ADSB plugin does for aircraft.

Note that those messages are NOT NMEA-0183 messages. The actual AIS frames don't look anything like that.

I don't know how different the message format coming out of AISCatcher is from what DireWolf generates, but if they aren't either KISS-encapsulated or AGWPE-protocol-encapsulated, YAAC won't understand them.

I can put investigating the AIS-Catcher's protocol on my backlog of things to do for YAAC, but it won't get done immediately.

[Edited Message Follows]

Is there a way to have YAAC read the NMEA-0183 messages from AIS-Catcher? I see that there is a plugin for Direwolf but the message format is a little different. I also tried the NMEA-0183 TCP plugin and tried to have it read from the external AIS-Catcher TCP source to no eval. AIS-Catcher will send messages via UDP and TCP to YAAC, and YAAC is reading them, but they receive JSON errors. The strings that AIS-Catcher sends look like this:

!AIVDM,1,1,,B,33L=LN051HQj3HhRJd7q1W=`0000,0*03

Here is a link to the AIS-Catcher software...



Any help is greatly appreciated...

That's very strange. What platform and operating system were you using? And which specific packages of Java distributions?

For example, some Linux distros split the core Java Runtime Environment (JRE) from the AWS/Swing graphics support, so if you are on a headless system, Java will still work without failing because it won't try to open the graphics display. If you only installed openjdk-jre-headless, YAAC would fail because it uses the JRE graphics libraries and they wouldn't be present to allow YAAC to use the graphics display.

I recently downloaded and installed YACC on my machine. None of the JREs I had would allow the app to start without crashing. I had to download the latest from Oracle.

I have YAAC running fine using a Pi with the 32 bit PI OS Buster using 73Linux to install YAAC.

I tried to install YAAC using 64 bit PI OS Buster and it failed to start.? The error message is
./YAAC Line 2: java: command not found.

I looked on the website??at the?
Raspberry Pi Detailed Installation Directions
and followed them.? When I got to?

apt-get install openjdk-8-jre unzip libjssc-java?

I get an error message:

Ah. That makes a lot more sense than constantly having errors. Thanks again!

Andrew, another dumb question. When the RF or IP boxes turn red briefly that mean it couldn't send (? or receive, or both?) through that channel for some reason? Is there a log somewhere that might show what that reason would be?

Andrew,?
Thanks for the information.
Weirdly, I restarted YAAC to work on your info, and it came up centered on my current location which the GPS would have provided.? And it also started displaying nearby beacons.? So all is well, somehow.
