Now you can export nice DBus interfaces from any source plugin. Here's a custom "GpsInfo" interface provided by the gpsnmea plugin: % ambctl Automotive Message Broker 0.13.800 [ambctl]# get GpsInfo GpsInfo { "GpsTime": dbus.Double(1050585131.0, variant_level=1), "FixSequence": -1, "Zone": 0, "Fix": 1, "Time": dbus.Double(469297.344, variant_level=1), "RawNmeaSequence": -1, "SattelitesUsed": 0, "SpeedSequence": -1, "SattelitesUsedSequence": -1, "GpsTimeSequence": -1, "RawNmea": "GPRMC,025856.739,V,,,,,0.00,0.00,311214,,,N*48", "Speed": 0 }
