raspi-aprs-weather-submit for Raspberry Pi - ARM Platform.

This code was inspired/copied from https://github.com/rhymeswithmogul/aprs-weather-submit and adapted to run on the Raspberry Pi ARM platform.

This is a repository with small adaptations to run on Raspberry Pi - ARM Platform, among the changes are:

• Changing the return code comparison of the arguments menu in the getopt_long main.c function (return 255 instead of -1);
• Safe use of the strncat function calculating the buffer value without overflow (aprs-wx.c);
• Removed temperature field from packet header and moved to weather data field;
• Adjusted Agent Suppression Option logic;
• APRS_IS, no longer optional - Now is default - fully integrated (#define HAVE_APRSIS_SUPPORT 1 removed);

This code was tested using: Raspberry Pi Model B V2.0 / 512MB RAM, SOC BCM2835 running Raspbian GNU/Linux 10 (buster)

Legal Notices

To use this app, you must be either:

1. a licensed amateur radio operator, or
2. a member of the Citizen Weather Observer Program in good standing.

Anyone can use this app to create an APRS packet. However, to send it to the APRS-IS network, you must have an account on an APRS-IS IGate server, as well as an amateur radio license or CWOP identifier.

How to compile:

sudo apt install autoconf automake libtool
autoreconf -i
./configure
make
make install (if you want to install in your system path)

ps> use "make clean" to clean binaries before re-compile

How to use:

./raspi-aprs-weather-submit --callsign PPPXXX --latitude 12.34567 --longitude -12.34567 --server brazil.d2g.com --port 14579 --username PPPXXX --password 1234 --temperature-celsius 22.0 --altitude 600.5 --pressure 1013.0 --humidity 50.5 --wind-direction 0 --wind-speed 22.5 --gust 31.5  

Or, if you just want the raw packet for your own use, don't specify server information:

./raspi-aprs-weather-submit --callsign PPPXXX --latitude 12.34567 --longitude -12.34567 --temperature-celsius 22.0 --altitude 600.5 --pressure 1013.0 --humidity 50.5 --wind-direction 0 --wind-speed 22.5 --gust 31.5

• Altitude (-A, --altitude)
• Barometric pressure (-b, --pressure)
• Luminosity (-L, --luminosity)
• Radiation (-X, --radiation)
• Rainfall in the past 24 hours (-p, --rainfall-last-24-hours)
• Rainfall since midnight (-P, --rainfall-since-midnight)
• Rainfall in the past hour (-r, --rainfall-last-hour)
• Relative humidity (-h, --humidity)
• Snowfall in the past 24 hours (-s, --snowfall-last-24-hours)
• Temperature (°F) (-t, --temperature)
• Temperature (°C) (-T, --temperature-celsius)
• Water level above flood stage or mean tide (-F, --water-level-above-stage)
• Weather station battery voltage (-V, --voltage)
• Wind direction (-c, --wind-direction)
• Wind speed, peak in the last five minutes (-g, --gust)
• Wind speed, sustained over the last minute (-S, --wind-speed)
