Re: Help with TNC9k6 setup

Don,

Oh, and please forget trying to get the TNC attached.  This is all automatic if you have a TNC-Pi2 or TNC-Pi9k6 plugged in.  Again, there is nothing you need to do.  If the new user interface shows the AX.25 service as running, then it is.

A lot of the confusion is “gone” as it were and I’m finally gotten with the program.  I get the whole access via phone, etc.  I got a clean image burn this evening and some of the issues I was having were mitigated, mostly I think because I followed normal steps as opposed to jumping around.

 

I still have a couple of issues:

 

  1. When booting fresh I have to log into the PI using the password.  It took me till just about 5 minutes ago to reboot and try to access the PiGate without logging into the RPi.  Viola! Another cloud removed.  I was hung up on the RPi having to be “running” in order for the software to be running.  So that was take care of.

 

  1. I have updated my location Lat/Long in decimal coordinates  to my location (match the format in your video 4) and I get zero RMS stations near me.  Yet I know of at least 1 which is 5 miles away.

 

  1. I have created and sent two emails via Telnet – I’ve yet to receive them but I think that WL not the PiGate.  BUT I have noticed the following error when viewing the polling log: wl2ktelnet: WARNING: grid square not specified in config file.  Is that in the PiGate or on WL2K?

 

My next step is to find the web pages I found earlier that described how to attach a TNC to the AX25 and make that available to the PiGate so I can start evaluating/testing RF sending.

 

As I said before, I’m more of an operator than a technician and it takes me a bit to catch up.  But once I catch up and the lightbulb goes off I’m there in full.  I’ve seen so many alternatives to how this can be used in our normal deployment methods.  My only challenge is how to make use of this at a shelter when I only have one reliable antenna available inside the shelter room. My current thought is leave the PiGate in my truck with a 55 Ah battery (to cover the period when the hurricane is blocking a good bit of sunshine) and a solar panel on the dash for when the sun is out to keep the battery going.  Connect that to the truck radio (running off the same battery) and duplexing to my D710.  Needs some more thought but that is where my head is at for the moment.

Don,

 

As I said before, there is nothing to do by using the Raspbian Desktop.  There is no software to run, no configurations to be made, nothing.  All administration of the PiGate device is done using the admin web pages, especially the new interface which gives you lots of capabilities.  There is absolutely nothing to be gained by logging in directly.  The OS and the desktop GUI are there only because they come with the Raspbian disto.

 

Any sending of email is done using an external email client that is running on your laptop, tablet, or smart phone.  There is nothing on the GUI to use unless you want to use the rather crappy Claws email client.  There are so many more that will work that are much better.

 

That is all the PiGate is designed to do, send email to a Winlink RMS station.  If you are looking for something else, you're looking in the wrong place.  If you want a Raspberry Pi to use as a computer desktop, you should just use the standard Raspbian download or maybe one of the others some of the other hams have made up, like HamPi.

 

Sorry if I seem blunt.

Lots of confusion on my part so please allow for that.

 

I can see (finally found your videos) how you have an all in one.  Not sure this fits my imagination of what I was looking for but I certainly see the utility and usefulness of it.  I’m working how to make this part of my process at a shelter.  Having said that I’m working through a limited understanding of Linux and the Pi in general so I had a checklist of things to accomplish.  That was the back and forth of the terminal.

 

As for the Bluetooth my “plan” was to use the Pi as a computer and not have another method of accessing the Pi than the Pi itself.  I didn’t want wired mouse/keyboard and actually had a Bluetooth set up before flashing your image.  At present I am VNC’d into the PI to work through your software and get a feel for what it is capable of.

 

In the meantime I’m working my way through the videos toward understanding how to get the PIGate on the air.

Don,

 

Sorry, I don't support the OS and any problems you may have with it.  Again, you don't need a keyboard and mouse connected to the PiGate to use it.  I probably didn't include it on the OS build because it's unnecessary.

Sorry for the barrage 😊  I am apparently having issues setting up Bluetooth to get a BT Mouse and Keyboard on the Pi.  I did this on an image of Build a Pi but when I run the same comment here (sudo bluetoothctl) the terminal window does not respond.

Oh and one other thing, when I click the items on the top bar (Web Browser, File Manager, Terminal) I get a prompt to run them in terminal or open as it is identifying them as an executable script.  I’m assuming that is normal for your image? I’ve never seen that behavior in Linux before.

Don,

 

I would not mess with the settings in any of the files on the PiGate image.  They are all there specifically to work with the TNC-Pi2 or TNC-Pi9k6 and if you make changes, it may not work.  I also wouldn't mess with any of the OS parameters, like turning the serial ports on or off.  Everything is setup correctly and it's really a plug and play image.  All you need to do is the initial setup outlined in detail in the docs.

 

If you have made changes, and you don't remember how to put them back exactly as before, just copy a new image to the SD card.

That makes sense.  I just tip toed my way in a clean flash of PIGATE and could not get the parameters (again) even though I had shell through serial off.  I traced the error (I LOVE GOOGLE!) to the AX25 director and AXPorts.  Turned off the TNC line rebooted and got parameters – so it is still there LOL.  BUT I did find the TNC line and went – hmm bet that would help!

 

So now I’m off to read up on the AXPorts file and how to set that up.

 

Slowly but surely I’m going to win this skirmish.

 

Thanks for the response and being there as needed.

Don,

 

The TNC-Pi9k6 appears on the serial port as a KISS TNC modem.  Only software that "speaks" the KISS protocol can us it.  That would be one of the packet software suites, like Pat, linbpq, PiGate, APRS, etc.

 

Use one of those programs to unlock the "secrets" of the TNC.

I purchased the pre-built board off Etsey that is intended to be a “hat” to the Pi.  It is on the GPIO pins and lights up properly when the PI boots.  I can get the parameters from the board so I know it is connected and communicating at least at that level.  But my question becomes – now what?

 

I can’t find any references to how it gets configured, what software to use, how to use it, etc.  I have put the KM4ACK Build a Pi on a card and have pieces of it working, but frankly I don’t know (or can’t find?) enough information on how to connect APRS (for example) to the TNC board.  I tried to list serial ports on the board and get nothing back (as in there are no serial ports?) But I have serial ports enabled.

 

At this point I’m looking for how I could connect YAAC (for example) from the PI and set up a serial connection to the TNC in an attempt to get an APRS signal to a radio and audio back.

 

Also from your comment the Teensy board is loaded, how to I look at those directories to see that software from the RPI interface? I’m assuming the TNC talks to the Pi to permit viewing those directories somehow?

 

As you can see I’m relatively lost.

Depending on which board you purchase the appropriate firmware is pre loaded.  For instance if you get a TNC configured with the Raspberry PI headers then it has firmware loaded to interact with the PI using the GPIO pins set aside for serial communications (19200 baud btw).  If you get the "stand alone" TNC then the firmware loaded is for that specific configuration.

I have tested our TNC's with Mark's PiGate image and I don't recall having to change any settings.

One other item.  You can find pre-compiled binary's for the TNC9k6 on our site: http://www.wvcarc.com/p/tnc-96k-resources.html
