Re: Direwolf APRS I-Gate over Cellular
Bryan Campbell
¿ªÔÆÌåÓý
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.? 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. . KD0GYL . On 2/24/17 6:37 AM, Jared Yates

Re: Direwolf APRS I-Gate over Cellular
Jared Yates
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?

Raspberry Pi 3 with Direwolf I-Gating to a local installed copy of
APRSC talking over the Internet over GSM or 4G LTE mobile Wifi hotspot. Using APRSDroid to talk to Direwolf over Wifi. Have it working now. Works great. And, if you connect a radio via Tigertronics Signalink USB soundcard to the Pi 3 it allows you to I-Gate for other RF APRS sources. Personally used it in this manner and it works great. But, make sure you filter heavily so that you don't inadvertently I-Gate for anyone else while you are moving . . . APRS police get their nickers in a twist over that kind of thing. KD0GYL |

Direwolf APRS I-Gate over Cellular
Jared Yates
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. |

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. -- Kenneth Finnegan, W6KWF |

Re: Raspberry Pi Automatic Startup fails
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. Arnold KQ6DI From: "David Ranch dranch@...

The dw-start.sh script *requires* that the shell running the script has a Xwindows system running (be it on the Rasberry Pi's HDMI port, VNC, etc) first.?

If you want to start Direwolf in a headless fashion (no Xwindows, VNC, etc) yet have things restart when required, I'd recommend to review N7NIX's systemd "unit" files for Direwolf: ?? #The systemd unit for Direwolf ?? ?? #See the bottom of this install script on how to install it ??

Raspberry Pi Automatic Startup fails
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. Suggestions? Arnold KQ6DI |
FILTER in Rx
Max, 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.

Re: IGFILTER in Rx only iGate
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...)
