Detailed Description

The DataSource component is used to connect to devices that either send or receive strings, such as a bluetooth printer.

DataSource is a parent of NmeaSource. DataSource can also receive NMEA strings, but if your workflow requires the use of devices that transmit NMEA strings, you should use NmeaSource.

For an example of this component in action, refer to the code sample for DeviceDiscoveryAgent.
