Re: Bluetooth SPP w/ APRSDroid

 

I will have to give it a try like that also. I've been using my phone as a wifi hotspot ap for the pi and connecting to the pi with APRSDroid in that fashion. Although Bluetooth would be a more viable option for a better setup on phones that can't do this.

David,

So it does sound like direwolf 1.4 is still an upgrade of functionality.?

I had to drop to a new fresh load of Compass and run Basil's installer scripts for working with the UDRC-II soundcard, but it worked for setting up the entire ax.25 stack and Direwolf 1.3, I'll try 1.4 in a separate directory to see if I can make the build run.

Hello Nick,

It sounded like the 1.4 build had more to the emulation than I thought. Honestly, I don't think I need the TNC2 emulation as much as a functional terminal and a functional way to use it remotely from another system so it can be a shareable resource. (Like to a windows client running RMS express)

Direwolf has two ways to do this:

?? TCP-KISS : you can use your local network to connect to Direwolf port 8001 and send/receive KISS frames.? Any applications out there that support TCP-KISS will work.? One example program that supports this is the APRS program APRX

?? AGWPE : you can use your local network to connect to Direwolf port 8000 to send/receive AGW packets.? CONNECTED-mode ax.25 session support is new to Direwolf's AGW stack in 1.4 and it works well.? With this, any application that supports AGW connections will work with Direwolf.? Agwterm, Outpost, RMS Express, etc.? They will all work.


The call command, or linPac sound perfect for local use.

Don't forget on being able to SSH into your Rpi via the network and run AX.25 CLI programs as well.? I personally run LInpac from a screen session and reconnect to it whenever needed.? Very light weight and fast compared to people using say VNC or TeamViewer to remotely display a terminal window running on the Xwindows desktop on their Pi.

Hello Arnold,

?
Is there a good, or proper way to load upgraded (dev) files? ?The only way I know is to delete the source directory in my computer (Pi), then get and make the newer version. ?Maybe that is the best way?

This is the fastest way though I would recommend to use the "checkinstall" approach instead of "make install".? A few supporting reason for this is:

?? 1. You'll get your new version of Direwolf installed as a .deb package so all the other packages & dependencies will be considering with it when doing OS patches, upgrades, etc.

?? 2. You'll now have a .deb file which you can easily install on other Rpis without having to install all the compilers, toolchains, and supporting programs.? This leads to smaller installs on your other Rpis


The use of checkinstall is covered in my "Raspberry Pi Setup with hardening for APRS & AX.25 Packet Project" doc.

I have since started work with Basil on the UDRC-II specific github scripts he made (n7nix repo) So far that built with no hitches, but I'd personally like to try upping the Direwolf build to 1.4 from the dev branch to test the TNC2 emulation.

The Dev branch is the newest available and is what 1.4 is based on.? Any of the .zip or .tgz files found on the Direwolf "released" page will be OLDER than .dev.? They might be more stable than the DEV branch but that's not currently true.?

Btw.. the new connected mode support in Direwolf is NOT "tnc2 emulatiom".? Direwolf doesn't support anything like that.? If you want to have software make things look like an old TNC2 setup, try out the linbpq32 BBS package.? Personally, I think it's a bit overkill for emulating a TNC to then create connected AX.25 sessions.?

Dire Wolf version 1.4 has support for traditional connected mode packet. ?You will need to use a separate terminal application such as AGWterm.

This connects over TCP port 8000 so the TNC and applications can be running on different computers and different operating systems. ?In the default configuration, Dire Wolf can handle 3 concurrent applications on port 8000. ?This is easily increased by changing one line and recompiling.

These two errors are pretty obvious.. there is some other program on your machine using ports 8000 and 8001.? To disable the use of those ports in Direwolf, edit your direwolf.conf file, find the lines:

?? AGWPORT 8000
?? KISSPORT 8001

and change them to:

?? AGWPORT 0
?? KISSPORT 0

If you're curious what's using ports 8000/8001, you can use the lsof program to find them but let's not get distracted.

To be honest and in your design, I would recommend to not send ANY beacons from Direwolf.? Instead, write a program / script / etc. that takes in all of the considerations of:

?? - incoming current from the panels
?? - time of day
?? - etc

From there, then use the Linux "beacon" program to send a on-off beacon as an APRS packet with whatever telemetry you want.? After that, the program goes back to sleep until it's time to see if it's time to send another beacon.

Hello All,


I am currently working on my fifth RPi/Direwolf APRS installation, and have ran into an issue which has me stumped and hoping someone in the group has an answer for, or at least,?can give me a kick in the right direction.


First of all, some background:
The latest APRS station will primarily be used to send back weather & telemetry on the vitals of one of our local clubs VHF voice repeaters. The repeater is solar powered and located in an EXTREMELY remote mountain in the far north of Canada, thus, during winter months,?(the shortest days of the year in late December, the site gets slightly more than 7 hours of sunlight a day), so the power budget is VERY tight (not to mention the financial budget our clubs 'Minister of Finance':-)) At the same time temperatures regularly drop at the site to -40 C (yes, that's also -40 F for you folks south of the border), which also drastically reduces battery capacity! (Don't think the battery folks ever tested their battery CCA's at our temperatures :-)). Operating the RPi at these temperatures doesn't seem to be an issue. We have one station that has seen these temperatures on several occasions and is still humming away. Moisture on the other hand is a different story... Elmer Tip from years of?experience in this environment: If you expect extremely low temps, seal up & insulate your electronics,?but before you do,?toss in?a few Silica Gel packs to suck up the moisture?and prevent frost forming on the electronics & shorting it out.


I have already taken care of all the usual paths of power conservation (right down to turning off the LED on the Pi Zero to save that extra 5 mA), but had another idea that would help conserve more power at the most crucial times, but I'm not quite sure how to tackle it.


One of the previous APRS stations I built was a mobile with GPS module using the SMARTBEACON/TBEACON. Worked great but got me thinking,?"Would it be possible to do the same type of ?Tx interval variations using the CBEACON?"


For Example: With GPS SMARTBEACON the Tx interval can be varied based on the speed travelling (faster...more packets, slower...less packets).?Might it also be possible to?send a CBEACON in the same manner, ie. based on temperature readings taken from a temp sensor on the batteries? (Higher temperature...more packets, lower temperature...less packets).?Guess you could call it a SMARTCBEACON?


I've read through the Direwolf manual, scanned the group and searched for any similar solutions, but nothing?showing up.


Has anyone out there done anything similar or have any thoughts on how it may be done? Any help, suggestions would be most appreciated!

Re: Smart...CBEACON????

I wonder if you could hook a thermocouple to a gpio then point a speed reading to that gpio pin. ?You could the use that for your smart beacon, perhaps?

Never done it, just thinking....
