Hi all,

After upgrading to beta v178 I noticed that the DIGI does not work anymore.
Am I the only one having this problem?

73 de Demetre M0SUY

On the AGWPE or KISSoverTCP port between YAAC and DireWolf, is the port enabled for transmit? If not, then YAAC will not send any outgoing packets through that port.

This capability is there to allow receive-only operation (such as when not yet licensed or not wanting to transmit spurious packets to a network); for example, I do this when working a bicycle event because I am not Net Control or one of the SAG vehicles, but am merely monitoring for problems in case a SAG's tracker needs to get fixed when they arrive at my rest stop.

However, being in receive-only mode does prevent YAAC from sending anything.

Subject: [yaac-users] Messaging with direwolf working as a digipeater

I am working on an experimental build of my system. it is a RPI4 for its better video resolution running Direwolf and YAAC with a NWDigital draws board. Using direwolf as digipeater it works well and will start a boot up when the RPI starts. YAAC works well showing the map and all APRS systems. The issue is I can't beacon or send any messages in YAAC. I am not sure is the path between YAAC and direwolf is not bidirectional or I have a setting wrong. I would like to have messaging working it helps when you need to message a SAG. Please let me now what to check and I hope direwolf working as digipeater is not causing issue. PS I really like the newest release now that I have played with the release.

Hi Dave,

Thanks for reply OM, I fixed it after Andrew reminded me about th e dialout group. I hadn't used LINUX for a long time and I had forgotten!
Now it works FB!

73 de Demetre M0SUY

You probably need to start YAAC, "AFTER" connecting/pairing/binding the device to the computer, and verifying what ports the system creates and makes available.

At least, with Linux Mint, that's what happens here with other Bluetooth devices.? If the virtual devices do not exist when a program starts, it cannot see them, no matter how many times you re-plug stuff.?? Some software can re-scan for available devices/ports, not sure if YAAC can do that.

Hi Andrew,

Thanks a lot for your help. I had forgotten about the group dialout. Once I included myself to this group now YAAC works in my LinuxMint Desktop FB FB FB!

Now to find a way for the Bluetooth connection to be persistent across restarts, maybe put the command in Crontab?

BTW we have used YAAC to install an APRS DIGI & IGATE on a Raspberry Pi 3B which replaced our local IGATE's PC that was power thirsty 24/7/365 and we are very happy with the way YACC works!

73 de Demetre M0SUY

The RF comm device can't be persistent because you don't have the device up 24/7 connected to your Linux system. Every time the Bluetooth device (or the laptop) powers off, you will lose the connection and have to rebind it. Now, whether your Linux distro supports remembering previous bindings and rebinding them again automatically is another issue, but not a YAAC issue.

Regarding the IOException, can you send me the entire error message (including the stack trace)? Easiest way would be to email me the YAAC.out file from your YAAC log directory. However, my suspicions include your user account not being a member of the group that owns the /dev/rfcomm1 file (such as dialout), which is a typical problem for Linux users not being able to open serial port devices. Alternatively, it could be an issue with trying to set attributes that may not exist on the Bluetooth device (such as baud rate). Either way, I need to see the complete stack trace to determine where it is failing.

Hi there,

I just did this and now there is a device rfcomm1 created in /dev directory. Any idea How do we make this persistent at every startup?
Now I see my APRS Voyager being connected when I click at the Bluetooth Devices icon.

But unfortunatelly YAAC beta version 178 still cannot open /dev/rfcomm1.
When I try to enable /dev/rfcomm1, I get a message saying "java.io.IOException: unable to open Serial_TNC connection /dev/rfcomm1"

I hope now Andrew can help with this one!

Hi Anrew,

I have paired my device(s) to my computer but I still can't see any rfcomm devices in /dev directory. I will try them both again today and see what happens!

BTW the same devices work flawlessly in my Windows 10 computers when I use APRSIS32 and they are recognised as Bluetooth devices not as Serial Devices by the OS.
So I can fo APRS using APRSIS32 just fine.

YACC on the other hand expects to see a COMport and each one of these devices create 2 COMports in Windows 10. No matter which one of the two I try to use, YACC cannot see this COMport.

After you have paired the radio with the Mint computer try running:
hcitool scan
which should show you the mac address of the controller in the radio. Next run:
sudo rfcomm connect /dev/rfcomm1 <MAC_ADDR>
Now you should be able to see rfcomm1 when you list the /dev directory. Use /dev/rfcomm1 in YAAC.

I don't have a D74 to test with with but this is the method used with the Mobilinkd TNC which is also Bluetooth.

Did you bind your Bluetooth devices to your computer? Until you do that, the /dev/rfcomm devices won't appear.

Hi Andrew,

Thanks for quick reply OM.

Unfortunatelly Linuxmint cannot see any /dev/rfcomm0 or rfcomm1 or any other rfcomm devices because they are not created in /dev/ directory.
I have paired my APRS Voyager succesfully as far as I can see. Do I need a plugin of some sort?

73 de Demetre M0SUY

You should be able to bind the Bluetooth serial ports (SPP protocol) to your Linux laptop. The devices should then appear as /dev/rfcommN files which the YAAC Serial_TNC port driver should be able to open. Note that you will need to put the APRS Voyager in KISS mode to work with YAAC.

Hope this helps.

Hi all,

I have an APRS Voyager and a TH-D74 and I would like to connect their internal Bluetooth TNCS to YACC.
I have managed to pair my APRS Voyager to Linux OK but I can find how to make YAAC see this modem! Which port do I use in settings?
Any idea on how to go on about it?
I use LinuXmint 20.3 Una

It's not nearly as nice as I would like, but you can go to Locate->Landmark, type in a street name, and see if you find any matches. Of course, since they will probably be on Main Street and every town and village has a Main Street, you will probably get a lot of matches. Once you find a suitable match, click on that row of the search results dialog, and the map will pan-and-zoom to that geographical feature.

Of course, this only works as well as the crowdsourcers who entered the street data in the first place. I've made a lot of edits on the OpenStreetMap website to correct errors and missing names in my local area and add missing data (like the township office buildings for each of the 63 townships, cities, and boroughs in the county my ARES/RACES group serves). And then those changes have to wait until the next snapshot is released by the OpenStreetMap Foundation, and I download that snapshot and import it into YAAC.

Andrew,

If I may ask another question. I kept getting request to search an address on the map. Several times during the event I got an address to pick up a stranded rider. Although we got there it would be nice to input the address and it shows up on the YAAC map. Then everyone can see the location see when a sag gets there to help

Working perfectly!
Thank you for the quick fix.

changes and updates include:
1. fix typo in OpenTRAC object entity numbering introduced in build#177
2. better handle compile version issues
3. officially release the eventlogger plugin

Greetings.

Thank you for the clear stack trace of your issue. It made it very easy to troubleshoot.

It seems the folks at Oracle changed the constraints on the Hashtable class between Java 8 (which is where I always test for backwards compatibility) and Java 11. I have corrected this issue, and will be releasing another build Real Soon Now[tm], as there was another feature I wanted to get out the door.
