You can check messages pending by going to MAIL in the to section and type APRSM, then when it connects will let you know if you have any pending. Here is a screenshot:

Check out APRS.wiki you can opt in to use it with both sms and mail. Mail is store and forward I know that. Not sure if SMS acts the same way.

?Hi Hank,

Yes it does if you use UI-View and an add-on called UI-Store & Forward. There is also a UI-BBS which works as a Bulletin Board.
You can find this information here: https://www.apritch.co.uk/addon_uiview32.htm

I wish other developers (hint to Lynn Deffebaugh) would add this facility to their APRS Software because unfortunately G4IDE, author of UI-View is SK. Still there are many people still interested in UI-View and all it's add-ons and they keep UI-View alive.

I do not know of a store-and-forward feature for APRS at this time.?? I seem to recall that someone was working on a mailbox-like feature, but I'm not sure now where I read about it or how it was going to work.

Suppose you are using an RF only setup and send a message to someone who is not on the air at the moment. Does aprs have the capability to send a message to that person and have it stored somehow for later retrieval by that person?

If you create any monitoring device that acts like a TNC and given a distinct CALL-SSID, you would connect to APRSIS32 as an RF port or configure APRSIS32 as a local IS-server and connect through it.? This gives you the best of both worlds.? I am not sure APRSIS32 does cross port (RF) digi-peating, so the local IS-server might be the better interface.? Even that might take some special filtering. ?Again, the device would need to do the packet creation. ?

?

There are APRS libraries for Python and/or Arduino.? Also, sample project code for each.

One example would be "trackuino" (TX only) as a starting point.? I believe it was written for balloons or rockets so has Telemetry packet source code to look at.?

You could strip out GPS and other portions that aren't needed.? I've messed with this a bit, but not to put together any type project.??

?

I am not sure why your Arduino project for monitoring the couple of devices is having issues.? From your comments, it appears you are not reading any values directl;y through the processor ADC.??Maybe because it is coming in through serial.? Timing is critical for serial decoding.? Are you using Software Serial??

?

For a couple of my projects (mainly Icom CI-V work), I had to swap the Software serial (SWS) to debug and hardware serial (HWS) ports for device interfacing (CI-V).? For me software serial didn't handle the 2-stop bits, so hardware serial was needed.? I found the Arduino HW serial port handled things much better.? I also changed the 'debug' sending out the SWS port to only sending every second or so.? Eventually, I moved to a Arduino ProMicro which has a separate hardware serial input.?

?

Or if you need more processor power try a STM32 BluePill (or BlackPill).? I just started messing with them myself.??

Just a few thoughts ...

?

Not sure this is exactly an APRS-IS thread any more though (other than interfacing like the RF or local server port comments).

Good luck! if you decide to act on this more.

Hi Rob,

The idea came up during a club breakfast conversation with another ham.? He was noting that he could bring up his home's solar production report on his cell phone, and I noted that I sometimes check the outside temperature by looking at my home weather station's APRSIS32-based reporting via aprs.fi.? I have a small off-grid solar system for when the power goes out, so, the thought went, why not tie my solar data into APRSIS32 as well?

The first thought was that the weather station's computer interface (WeeWx) is a simple Python script, so perhaps I could modify it to hijack a couple of the weather station data fields and substitute the Solar data?? Nah...

Your suggestion to replace the Arduino with a Pi-zero could definitely work, and would definitely have advantages.? The Arduino is pretty full, capturing, parsing, and displaying the Victron serial port's telemetry.? Two devices worth - the charge controller and a sine wave inverter - and it crashes every few days.? No idea why.? That said, its purpose was only to provide a visual display of system status, which Victron normally supplies through a much more expensive solution.? The other manufacturers of solar controllers and inverters tend to put displays directly on their devices, but I needed a product that was known to be RF-quiet and compact in size.? Making use of the serial port was just a way to be cheap and have some fun with the Arduino, while enabling me to use the Victron equipment.? I could use a Bluetooth app on my cell phone, but in a power outage situation, I didn't want to rely on it.

The down-side of having a Pi generate the IS traffic was what I was hoping to avoid by using APRSIS32, that of formatting APRS packets.? I know and appreciate what Lynn had to go through in deciphering the APRS spec, and didn't relish the idea of repeating his experience.? Lynn's summary corrected some of my misgivings, besides that APRSIS32 doesn't offer the feature I was looking for.? I'm also guessing that by now there's probably a Python library somewhere that would do the heavy lifting.? Your idea is something to consider.

To answer your question, yes there would need to be a small program or script that would periodically read from a serial port and write a string of numbers to the telem.txt file, something I've done before.? Just like with the weather station wxnow.txt interface, the data would be scooped up by APRSIS32, formatted for APRS, and forwarded to the active ports.? One thing I'd lose by not using something like APRSIS32 is that the RF world wouldn't see the data directly.? It's not a huge deal for me, but others wanting to use such a facility might appreciate the full APRS experience that a proper, modern APRS client would provide.? Having something easy to access could make APRS all that more useful by lowering the barrier to entry for general telemetry, and I figure we don't need everyone hacking their own programs to shovel data to the IS, with all the chaos that could (and has) caused.? There's a huge difference between logging data to a text file and properly interfacing with the world-wide APRS IS system.?

Greg,

I am curious what you would use to create the "telem.txt" file that APRSIS32 would read and send as a Telemetry packet?

?

From your description, you would need a terminal emulator (like TeraTerm) or a "home brew" application to read the serial stream and save it to a file.

If you swapped out your Arduino for a Pi (say Pi Zero W) and used a I2C Analog to Digital Converted (much better than the Arduino built in), then Pi could send the data to APRS-IS.

NOTE:? you could use an I2C LCD as well.?

?

Another option would be to send the data from the Arduino to "a Pi" (or other computer) over serial in something like a JSON format through the command line and feed it into a home brew application to parse it and send the packet.? It would look something like:

?? $ cat dev/ttyS0 | mytelem

where mytelem is a executable that takes command line data, parses it, generates a telemetry packet and sends it to APRS-IS (after login and passcode are sent).

?

Just some thoughts.
