Uploads received position data from Brandmeister to APRS-IS.

Brandmeister uploads position data to APRS-IS as simple APRS objects, without correct path information. bm-pos2aprs listens on MQTT for position data from Brandmeister, and uploads them to the APRS-IS with correct station->repeater paths. The script also takes care of transmitting received APRS messages as short DMR messages over Brandmeister.

Additionally you can turn on the usage of multiple service IDs. In this case the APRS symbol of position reports depend on the used destination ARS/RRS ID, not the one set in SelfCare. For example, if you set your radio's ARS/RRS ID to the ID of LOCATION_SERVICE_ID9, you will have the symbol of a car. If you set your radio's ARS/RRS ID to the ID of LOCATION_SERVICE_ID7, you will have the symbol of a walking person.


  • You'll need PHP CLI (ex. php5-cli).
  • Rename (and edit) config-example.inc.php to config.inc.php.
  • The Registry MySQL database is the database found on each Brandmeister server. Make sure your database user has select access rights on Registry database tables.
  • You have to set the APRSGate's number to a not used number (for ex. 5060) in BrandMeister.conf. This ensures that Brandmeister will not upload positions on it's own, and lets this script do the job.

To use multiple service IDs, you have to adjust ServiceWrapper settings in BrandMeister.conf for all LOCATION_SERVICE_IDx setting:

// ServiceWrapper Application
ServiceWrapper :
  // List of mapped service IDs:
  // <Type>, <Private ID>
  // Where <Type> in:
  //   1 - Registration Service
  //   2 - Messaging Service
  //   3 - Telemetry Service
  //   4 - Location Service

Running as a daemon

It's not ideal to run command line PHP scripts as daemons, but I had most of the routines used here in other projects, so I wrote this in PHP. Feel free to rewrite this to a better language.
