PolySync Core nodes subscribe to data from the Core bus in the form of high level message types.
The messages can be filtered by the subscribing node for specific sensor sources.
1. Sensor descriptors
sensor descriptor that uniquely identifies the source sensor.publish messages to the bus containing the sensor data. Each message published by these nodes contains a
The sensor descriptor contains a
ps_sensor_kind type to identify a kind of sensor, and a
ps_identifier which is unique within the same sensor kind.
1.1 Filter by sensor kind
Each supported sensor and hardware device has a unique sensor kind value defined by PolySync.
Filter for specific sensor types by comparing the incoming
msg->sensor_descriptor.ps_sensor_kind to the values in the supported sensor values table. Using the C++ API you can access this information with a call to
1.2 Filter by sensor identifier
Many sensors support─and sometimes require─a sensor identifier parameter to uniquely identify a sensor or hardware device.
Sensor 0 Identifier parameter can also be used to identify a specific sensor stream.
Filter for specific sensor identifiers by comparing the incoming
msg->ps_sensor_descriptor.ps_identifier to the parameter
Sensor 0 Identifier that’s stored in the nodes Sensor Configuration table within the SDF. Using the C++ API you can access this information with a call to
