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.
