The previous tutorial, Creating Your First Block, demonstrates how to create a Python block using the Embedded Python Block. The next tutorial, Low Pass Filter Example, demonstrates how to use filtering blocks in GNU Radio.

Message Passing Overview

Messages are an asynchronous way to send information between blocks. There is no sample-clock based guarantee when they will arrive and messages are not associated with a specific sample like a tag.

  • message ports to have to be connected like stream/vector ports






The next tutorial, Low Pass Filter Example, demonstrates how to use filtering blocks in GNU Radio.
