Re: Direwolf as IGate - Pseudo Kiss port in APRSIS32 Not sending receiving messages.

David Ranch
 

¿ªÔÆÌåÓý


Hello Dale,

?

I have direwolf set up as an IGate and using the Pseudo Kiss or AGW setup on my APRSIS-32,


Which version of Direwolf are you using and what OS are you running it on?? Are you using PTY-KISS, TCP-KISS, or AGW?


Data is being sent to APRSIS-32 and can see all the stations my Rx only IGate is picking up


In this configuration, are you IGATING from Direwolf or from APRSIS?? If you want messaging, I recommend you disable the Igate functionality from within Direwolf and do it from within APRSIS32.


1, Any message being sent to me does not appear on APRSIS-32 nor does it send any ack packet.

Make sure that the callsign configured in Direwolf is DIFFERENT than in APRSIS32.? Again, disable IGATING from within Direwolf and only use it as a KISS or AGW TNC.


2, Any message via?APRSIS-32?I send shows on my direwolf console shows direwolf trying to send it as a radio packet, however I have no Tx capable radio attached and is Rx only.


This might be a configuration issue but as mentioned above, just use Direwolf as a TNC and I think you're issues will go away.? This is only required since you want to support APRS messaging which Direwolf doesn't offer a direct interface to do today.

Direwolf as IGate - Pseudo Kiss port in APRSIS32 Not sending receiving messages.

I have direwolf set up as an IGate and using the Pseudo Kiss or AGW setup on my APRSIS-32,

Data is being sent to APRSIS-32 and can see all the stations my Rx only IGate is picking up.


I have 2 issues:


1, Any message being sent to me does not appear on APRSIS-32 nor does it send any ack packet.

2, Any message via?APRSIS-32?I send shows on my direwolf console shows direwolf trying to send it as a radio packet, however I have no Tx capable radio attached and is Rx only.


Is there a config I need to add or change for KISS/AGW to enable me to use a client attached as described.

Hi David,
?
Thanks for the RTLSDR-Airband info.? I will play with it.? Maybe there is an easy way to interface it with Direwolf.? I have play before with other RTL-SDR software like aisdeco to decode ship beacon on two frequencies and acarsdeco to decode airplane messages on 3 frequencies.? So, thought it should be possible to decode 2 or 3 frequencies within 2.4 mhz.

Hello Jose,

The rtl_fm tool only allows demodulating one frequency at a time but I recently came to learn of .? This software can support 8 "slices" per SDR dongle and was designed with the Rpi in mind.?

Is it possible to have a dual frequency receive with the RTL-SDR?

I tried this command for dual frequency received but the program quits with message End of file on stdin.? Exiting.

Re: IGate not sending rx data, only beacons

 

The APRS-IS servers remove duplicates. ?If multiple IGate stations submit the same packet, only the first one is retained. ?If some other station sent the same information a millisecond sooner, the duplicate that you send later is not kept. ? That could explain why your information is not showing up.

This document gives more information about how it all works. ?There are troubleshooting tips at the end. ?Specifically, you could use the "-di" command line option to see what is being sent to the APRS-IS server. ?You will need to use direwolf version 1.4 for all of the features mentioned here.

Re: IGate not sending rx data, only beacons

Keith,

I put it on another device earlier (o2 Joggler) not sure if anyone has used one of these but thought it would be useful as I can put a map on the screen.

I feel a bit of an idiot here as a friend pointed out that looking at my own raw packets won't show what I've actually heard or put through the igate. Only any thing I've directly sent like beacons. And the Magenta text doesn't show when relaying heard stations to the igate.

I looked under?
Last heard a station directly:

And saw a recent time then checked?

Stations heard directly by?2W0ODS-10?

And there are a list of stations there.

I thought it would show in Raw packets but I was wrong!
?
I've used APRS for a while on a Mobilinkd TNC2 and a Kantronics KPC-3 but IGate is new to me, but now it's starting to make sense.

Hi Dale,

It says 1.3 when it loads, no mention of beta.

Not sure which ¡®Keith¡¯ your asking. But I am currently running 1.4 but have not spent enough time with it for a full evaluation.

Keith,


What version of Direwolf are you using, is it 1.3 or 1.3 Beta?
My friend has just set a Pi up and his is working correctly, however he used plain 1.3

So not sure if something is broken in the beta...

I removed the digipeat line from my sdr.conf file as it has been suggested that for an RX only iGate, it's not needed.

Checking today, still only my beacons have been forwarded onto the internet.

Re: Pi Audio completely stumped

 

Arnold,

Did you ever find out what your problem is/was? I am having a very similar issue. I am setting up an Igate and Direwolf will not decode any packets.

I would go into detail, but I don't want to your thread.

Correct but if you waited a couple hundred milliseconds the RX would have started by then. If the packet duplicate check was done after the clear channel detection then you would weed out digipeated packets. If no packet was digipeated then the TX would be a short time after the RXed packet.

That seems like a lot of effort just to eliminate a few seconds of digipeater latency, but to each his own.

Aprx has nothing to do with clear channel detection. Aprx processes
packets handed to it from the TNC over the KISS interface and hands
back packets to be transmitted. Channel access and buffering is
entirely handled by the TNC.
So to do what I want to do I would need to hack direwolf. I do like that I can solve it in the interim using APRX

IGTXVIA 0 didn't disable anything.?

Keith, if you look at your Raw data on aprs.fi do you see anything other than your Beacons now? I still don't see anything other than beacons on mine after changing a few settings.
Re: IGate not sending rx data, only beacons

I did see a few [IG>TX] in the console so I just added:?IGTXVIA 0 to sdr.conf.

Maybe not but I'm certainly seeing more magenta lines flashing up my screen now. ?

With hindsight, maybe not as much as I'd expect so perhaps it's not quite the correct way to do it. ?Hopefully someone can wade in with a better suggestion.

From what I understand that isn't needed on a Rx only IGate?
Re: IGate not sending rx data, only beacons

I'm replying to myself now because I think I've resolved this.

In sdr. conf, I added a line:

DIGIPEAT 0 ig ^WIDE[3-7]-[1-7]$ ^WIDE[12]-[12]$

... and it now looks as though I'm relaying stuff from local RF onto the internet.

Hi Keith,

I just fired up APRSIS32 on my windows machine and connected to Direwolf on my Pi using port 8001, all the decodes are showing fine on there too.

I just hit "Transmit" on APRSIS32 and I saw it come up in magenta on the Direwolf console, but that is not being sent or seen anywhere.

The only thing that can be seen are beacons I send.

I've gone through all the conf files and everything looks correct.?
