Weird issue when transmitting larger files using VARA FM.

[oe3gwu]

I am Sysop of OE3XNR-11 and -10. We use Packet and VARA FM. So I am kind of familiar with those technologies.

Using VARA FM in a VM with Winlink Express, everything works perfect, I connect and send data all along, Packet after packet. I see the progress in the Vara FM Modem.

This is a reference picture for how it should look like - not my connection.

Using Pat, I send a Data Packet, then the modem resets, all bars disappear, it seems he negotiates again, then send one packet again, and so on. It is VERY slow but stable. What is the issue here? I use the latest version.

Thanks for reporting this issue 😊

I'm having trouble reproducing this locally, so it would be very helpful to get some debug logs from your end. Can you please provide full log output while running with the environment variable VARA_DEBUG=1? E.g. VARA_DEBUG=1 pat connect varafm:///....

Thanks!

[martinhpedersen]

Also, what's the output from pat version?

[oe3gwu]

Pat Version 0.15

Yeah, I can retry with Debug logs, but it will take until tuesday, because I am not at home.

Sorry for the delay, were some busy days.

Here is the debug log. There are too many PTT OFF / ON in the transfer comared to a Windows System. And I guess that is also the reason I dont get above speed level 3. With Windows I am on 7-8.

Perfect. Thank you 😄

I'm not completely sure, but I think this relates to a bug in VARA. It sends very few BUFFER updates, and certainly not after each Write call as it should.

This is a known issue, but I though my workaround was sufficient... but maybe not.

I think we need to experiment with a higher "magic number" (see link above). Unfortunately, I did not make this configurable. We need to change some code and/or make it configurable in order to experiment with different values.

I am currently moving to a new QTH, so quite busy with RL at the moment. I'll get back to you as soon as I have some time to work on this 🙂

Thanks!

What puzzles me is that in the GUI the bars disappear what already has been transferred. It looks like everytime he negotiates new. Also between every data transfer there are extra negotiations with speed level 1, and not only ACK's as usual. It is very weird.

Until solved, I use FX.25. Our Winlink Gateway works with both, and FX.25 is working really great, so no big deal currently.

Thanks for looking into it. If you wanna make tests, I am here to help.
