Re: Direwolf APRS I-Gate over Cellular

Initially used it in a mobile application using the APRSDroid for the GPS tracker function.? APRSDroid can also send short, text like, messages.

APRSDroid talks to Direwolf.? Direwolf talks to APRSDroid via AGWPE port or TCP connection.? Have used both.? Other software can also.

But, as an I-Gate or Digi, it was left sitting still for weeks without any issues.? Direwolf AGWPE port will shut down if not used regularly/often (documented intended behavior).

As for bandwidth, usual and customary bandwidth for AX.25 is 1200-9600 baud or 13-104 MBytes per day for a full link.? That is 389-3111 MBytes per month for a full link.

Depending upon where you live, and the number of APRS devices transmitting over RF that you can hear and for which Direwolf/APRSC will determine it should I-Gate, you might have 10-20% duty cycle at peak.? So, at the very worst, I would expect that you would see less than half a GB per month.? But, you can control that directly by having Direwolf use APRSC locally installed and just tell APRSC to ignore traffic outside a 1,5,10,20 mile radius.? You can also tell APRSC to just ignore inbound from the Internet.?

Lots of options.? And, yes, using a T-Mobile GSM SIM in a Wifi hotspot is the least expensive option for this application.? There are add on boards for the Pi that allow a radio/SIM to be added to the Pi directly.? But, they are much more expensive and are not as extensible a solution.? A GSM Wifi hotspot could service many devices simultaneously.?? For example, APRSDroid can talk directly to APRS-IS over the GSM Wifi link.? So, you could augment your cell data coverage with the Wifi hotspot.

For Advanced Users . . . Also, you can insert a router with queuing between the Wifi hotspot and all your devices that would allow you to control your bandwidth.? I recommend the Mikrotik hAP Lite.? It is inexpensive, small, USB powered and has a ton of features . . . including queuing.? Also, if you want to get a little more complicated with your setup, you can add a cellular connection directly to a little more expensive Mikrotik hAP (non Lite) router.? But, this is outside the scope of this list.

Thanks for the help. In this application the pi will be stationary. So you are using the pi's wifi to talk to a hotspot, and have your sim card in the hotspot? Are you using APRS Droid to work with the pi when you need to, or is the droid there all the time?? And by not much data, do you mean something like 10mb, 100mb, 1gb, etc?

Direwolf APRS I-Gate over Cellular

Jared Yates

#1807

Has anyone successfully used a Raspberry Pi and Direwolf to run an I-gate over the cellular data network? I have a remote location that doesn't have internet service but does have good cell coverage. I'm curious about the specific combination of hardware that would work, and what kind of data usage it would involve. The sim card is t-mobile compatible.

Please be more specific.
What is the exact version?
What is in the configuration file?
What appeared on the screen?
Were there any error messages?

There is no way to prevent APRS-IS from sending you implicit packets on a user filter port. Filters are simply additive to the implicit packets APRS-IS sends you regardless, and I'm not aware of any behavioral differences in APRS-IS connection handling based on q constructs.

20 packets per hour for implicit messages is pretty trivial compared to the APRS-IS keepalive packets which are sent every 20 seconds. Either of these are negligible traffic levels on unmetered Internet connections, so I wouldn't be concerned about it.

I tried version 1.4. ?It had a failure regarding internal filtering... ?Either receiver to iGate or receiver to transmitter. ?Basically it didn't work.

I reloaded version 1.3 WITH THE SAME CONFIGURATION FILE, and filters worked perfectly.

So, as far as I could tell, version 1.4 don't work properly.

direwolf version 1.3 always uses qAR. ?version 1.4 uses qAO for a receive-only IGate. ?Look at the comments in igate.c for more background on this.

Version 1.4 has a new client side packet filter to select "messages" only to stations that have been heard nearby recently. This is now the default if no IS to RF filter is specified.?

Humm, well I thought I had started VNC server, and it appears (to my apparent lack of knowledge) that the VNC server did start. ?I just hadn't logged into the VNC server yet. ? Maybe it's the wrong VNC server when DireWolf is looking.

The script does run, and it appears that it tries to start DireWolf, but DireWolf doesn't see a Xterminal and exits.

Beyond that, the links you provided are beyond my programming capability to even begin to figure out what is happening, let alone grab just the installation portion.

I wish this was clearer in the DireWolf documentation. ?As it is, this can't be used in a stand-alone configuration.

Raspberry Pi Automatic Startup fails

#1797

I'm having the same problem that others have posted.

I am running Raspbian version 8.

I have a Raspberry Pi running DireWolf as a remote digipeater. ?After a power failure, I would like DireWolf to automatically start. ?I have put in the Automatic Startup commands from section 6.1 of the Raspberry-Pi-APRS.pdf document, and it will not automatically start.

I have made the script file Executable by using the following:

sudo chmod +x dw-start.sh

What I found by looking at the Log file that is created is the script (from DireWolf) REQUIRES a display of some sort. ?The log file has:

Wed Feb 22 11:53:41 PST 2017

DISPLAY=:0

Start up application.

-----------------------

Wed Feb 22 11:54:41 PST 2017

DISPLAY=:0

Start up application.

-----------------------

Wed Feb 22 11:55:41 PST 2017

DISPLAY=:0

Start up application.

-----------------------

When I manually start a VNC server, then DireWolf will start, but NOT UNTIL I manually start the VNC server.

By looking at the script, it shouldn't get to "Start up application" unless a display was found, so it appears whatever display was found DireWolf didn't like.

There are range filters that work well, but only for position reports. ?I usually have them set fro 350 km so positions of 0N 0W get rejected, but weather is not a position. ?You could block weather, but that blocks all weather stations. ?An option I use for "undesired stations" is to filter out that station using -b/callsign filter. ?It only works after you discover the bad station and put in the filter, but it won't happen again.

Maybe I need to explain a little more.

This is a Raspberry Pi and it is going to be on a hilltop. ?I won't have any other computer or program running except DireWolf. ?This isn't about the Raspberry Pi, but it is about the IGFILTERS. ?

Tuning for what I want is perfect, except the choice for ZERO doesn't seem to be an option. ?I suppose a range of 1 km might do it. ?(But then I got a call on the Security telephone one day on the hilltop offering daily newspaper delivery. ?4 locked gates in the middle of nowhere...)

This should be possible with the IGFILTER config parameter. Just choose

IGFILTER m/10 t/po

Would send traffic within a 10km radius of my position and only position

Re: IGFILTER in Rx only iGate

#1794

Correction to below

IGFILTER  m/10 t/po

sends ALL packets and objects. Direwolf config suggests only the m/ parameter should do this.

Would send traffic within a 10km radius of my position and only position
packets and objects. Tune accordingly for your requirements.

This would imply to APRS-IS that you are a TX I-gate. If you use qAO
instead,  this should tell APRS-IS that you are RX-only. Not sure if
that would solve the problem. Also not sure if direwolf APRS-IS client
lets you specify the q construct. if not, you can run another client
on top of Direwolf modem, eg. APRSIS32. But if the confit option is
missing in direwolf APRS-IS client, someone should probably add it.

While I agree with you, we are not given any control over that. While
my station is not receive only, the other day there was a short band
opening and I received a single packet from a distant station 400
miles away via RF, and for the next three hours I received their once
per minute weather station packets. I counted all 180 of them. Seems
like a lot of wasted bandwidth. Not to mention it fills up my logs
with useless data. See if you can spot both problems!

I have a Receive Only iGate.  The T2 servers keep sending my iGate
packets they think are going to go to RF.  Obviously they don't, but
what is the way to stop getting iGate messages for transmit?
IGFILTER no send  ???
IGFILTER -everything ???

There must be a way that I haven't found because I get about 20
messages an hour that it wants to send.
