VPLive

VPLive is a program that connects to a Davis Vantage Pro 1 or 2 Weather Station console and displays the live data. It calculates the station pressure (i.e. actual pressure), altimeter pressure, and running averages needed to properly generate and send APRS/CWOP data.

It sends the weather data to the APRS/CWOP system. VPLive also has a feature that will force the VP barometer to update more frequently than the standard 15 minutes. It can run WeatherLink at regular intervals to allow WeatherLink to download the archive data from the console and write it to the archive file. It requires very little CPU time or system resources while running (for example, on an older 500 Mhz Pentium III, VPLive uses around 1/10 of 1% of the CPU's time).

What's new in version 1.1.10
  • Fixed problem with range validation of lat/long values in APRS setup screen.
  • Implemented new CWOP recommendations for offsetting the APRS upload time based on the last digit of the user's CWOP callsign.
  • Added a "wobble" factor to randomly change the send time by an amount less than 1 minute so that data is not always sent on even minute boundaries.
  • Removed manual entry of APRS server and port.
  • Server and port list are no longer hard coded into the program. That data is now in a file called AprsServers.txt.
  • Added feature for periodically and automatically downloading the AprsServers.txt file from the SoftWx website.
  • Default AprsServers.txt file specifies the first server attempt as cwop.aprs.net, port 14580, per the new CWOP specifications.
  • Added recognition and handling of "Port full" response from APRS servers.
