aprs - weewx extension for generating APRS-compliant packets

This weewx[1] extension allows the generation of APRS-compliant packets containing weather information collected by weewx. This extension was written for the purpose of easy integration with aprx[2]. When this extension is enabled, weewx will generate a new APRS packet every StdArchive.archive_interval seconds.

Installation: wee_extension --install aprs.tar.gz

Configuration: [APRS]

The APRS weather packet payload will be written in output_filename

    output_filename = /dev/shm/aprs.pkt
    # include_position:
    # 0: a positionless weather report will be generated (default)
    # 1: a weather report with position will be generated
    include_position = 1
    # In case of a position packet, symbol_table and symbol_code will
    # determine what symbol will be used to display the station (e.g. on
    # aprs.fi). "/_" is the default and will generate a blue WX icon.
    # A positionless packet does not include a symbol specification and
    # these two settings will be ignored
    symbol_table = /
    symbol_code = _
    # The string in comment will be appended to the end of the packet.
    comment = ''

Example of integration in the aprx configuration:

beaconmode both # Send packet via APRS-IS and radio. cycle-size 5m beacon srccall N0CALL-1 via WIDE2-1 file "/dev/shm/aprs.pkt"

Note: this configuration has the problem that aprx and weewx are not syncronized, so aprx may send out the same packet twice or miss one from time to time.
