Re: Beacon and Status message timing

#440

That's an interesting observation. What are the digipeater specifications for your beacon versus your status? If you can't reach an I-gate without being digipeated, then beacon transmissions without sufficient digipeat aliases (such as WIDE2-2) might not ever get digipeated, whereas if your status only uses WIDE2-2, it would be digipeated all the time.

What are your beacon and status settings, especially regarding digipeat aliases (possibly using proportional pathing)?

Hi Andrew

Do you have further thoughts on this?  Are my settings correct?  The issue seems to be that the status messages get digipeated more than the beacon.because yaac is indeed making the transmissions as far as I can see.

Re: java heap error message on rasp pi 3 when trying to download maps

#437

Hmmm... indeed, you haven't made much progress on the download.

Can you replicate this and then after it hangs for more than 10 minutes (or if it times out by them), send me the YAAC.out file from your YAAC log directory? The reason I say to wait 10 minutes is for standard TCP/IP timeout to occur, in case that is the cause, so either way I get an accurate error message.

The other question is: what exact date and time did you do this? I was upgrading my server around when you sent the original email. So were you in the middle of a download when I shut the server down for upgrade? I always check before I reboot the system, but it doesn't mean you didn't slip in between my check and when the shutdown script turns off networking.

Hi Andrew

?

My setup is very simple.? I have one beacon that I keep the default name for (default).? The position is manually entered (no gps).? Beacon type is Position.? I have free text.? The initial rate is 60, decay ratio 2 and slow repeat rate 1800.? The selected digipeat paths in proportional path order are WIDE2-1 first and WIDE2-2 second, so I assume WIDE2-1 would be the first priority followed by WIDE2-2.? (Now that I think of it, should this only be WIDE2-2?)? The status beacon is set up the same way with WIDE2-1 in the first position followed by WIDE2-2.? The inital repeat rate is 60, decay ratio 2 and stable repeat rate 1500.

?

There is not a lot of radio traffic in my area.? There are very few and I am not using time slotting.? I guess I’ll try using WIDE2-2 for both beacons and see if it makes any difference.

Hi, Joseph.

That's very strange behavior of the I-gates in your area, keeping your status messages and discarding your positions. What exactly are the settings for your position beacon? Mic-E or standard or compressed text position format? Do you have a free-text comment appended to the beacon? What are the initial and slow rates for your beacon and your status? How many different beacons do you have (only the default one, or additional ones)?

?

The other question is, how many transmit-only beacons are in your area (as in, jamming your position packets)? Are you using time-slotting (not recommended unless you're on a non-standard frequency and your time slots are coordinated with all other stations on the frequency)?

Re: java heap error message on rasp pi 3 when trying to download maps

#430

Are you trying to download maps, or import them from a .pbf file? What is the exact text of the error message? Copy-and-paste, please.

A Raspberry Pi is short on main memory by about an order of magnitude to be able to import a raw OpenStreetMap vector file. Adding swap space won't help; you'll just burn up your swap drive and melt the CPU. The importer logic needs at least 2 gigabytes of real heap memory to be able to handle an OpenStreetMap .pbf file of any significant size. You need to get the pre-imported files I make available on my website with the File->OpenStreetMap->Download Pre-Imported Tiles menu choice.

If you were downloading pre-imported tile files, how many of them were you importing? i.e., how many miles/kilometers of radius were you using? If you have a very fast Internet connection, it is theoretically possible for you to overload the Java virtual machine by opening the next tile file faster than the Java garbage collector can clean up after downloading the previous file.

Let me know what further information you have on the problem.

Re: Java 8_261 on Microsoft Windows breaks YAAC!

#428

Basically, yes. The actual gory details are here:

https://www.oracle.com/java/technologies/javase/8u261-relnotes.html

Note that the first issue in the release notes (after exhorting everyone to keep up on their security patches) is identifying that they've changed runtime libraries and the tools they've used to compile their Java virtual machine native code for Microsoft Windows. There's a file, msvcr100.dll, that is in the \Program Files\Java\jreversionnum\bin directory, that is used by both the Java runtime and the JSSC and RXTX native code DLLs on Windows. However, it has been replaced with a newer version in Java runtime 8_261 and later, so it's not there for JSSC or RXTX to use. Windows users using later releases of Java (9 through 14) will find similar issues if they take a patch update, if not now, in October when the next quarterly Critical Patch Update comes out from Oracle.

Note, of course, that there are different versions of msvcr100.dll, depending on whether you are in "Program Files" or "Program Files (x86)" (64-bit or 32-bit variant), so you can't just grab one randomly and drop it into your Windows installation of Java (if that is even allowed by your local system administrators). And I don't know if it's safe or possible to mix versions in the same running program.

So, my present plan is to:

Get myself a copy of Visual Studio 2017.
Recompile the native code in JSSC for Microsoft Windows using the 2017 runtime.
Build an alternate version of the JSSC jar file with the recompiled Windows DLLs.
Add code to YAAC to conditionally select the correct variant of the JSSC jar file based on the Java runtime version being used, for every release of Java from 8 to 14. I will assume that anyone still on Java 7 is using the old library version, and anyone on Java 15 or later will have only the new version. This will require researching Oracle's release notes to find which patch of each release is the transition point.

Hopefully, this will get everyone operating again.

I hope to have build 157 of YAAC out the door with these changes real soon.

Arrgh! They probably renamed the library package to something else. Gotta keep these Linux distros inconsistent..... :-( Which release of Raspbian are you using? Jessie? Wheezy? Or something else?

Unfortunately, the Bluecove library won't report the reason _why_ the library can't be activated. 

By the way, what do you mean by "installing" the plugin? All you do to install a YAAC plugin is unzip the zip file into the plugins directory (or just drop the .jar file in the plugins directory if the plugin is distributed as only a single JAR file). As long as you have the operating system prerequisites also installed, that's all there is to it.

Re: Anyone have a good Guide for Bluecove on a Raspberry Pi 4b

#422

Looks like I need to make a fix to not loading YAAC plugins if there is an installation problem to at least let users read the help pages for the plugin, even if the rest of that plugin doesn't work.

For the Bluetooth plugin on Linux systems, you need to have the native Bluetooth user-mode libraries installed so the Java code can call them. On a Raspberry Pi (or other Debian/Ubuntu variants), issue the command

sudo apt-get install libbluetooth libbluetooth-dev

On Red Hat, Fedora Core, etc., issue the command

sudo dnf install bluez-libs

Also, verify that you have all three of the following JAR files in your YAAC/plugins directory:

bluetoothport.jar
bluecove-2.1.0.jar
bluecove-gpl-2.1.0.jar

All three should have been installed if you properly installed the plugin from the bluetoothport.zip distro file.

There may be an issue that the native stub library included with bluecove for ARM processors is named libbluecove_armv5tel.so, which may not jive with the CPU architecture model on the Raspberry Pi. If it doesn't work after confirming the JAR files and native Linux distro packages are installed, get back to me, and I'll see about improving the plugin distribution with a suitable native stub for Raspbian.

Hope this helps.
