Sink and Source MIMO Errors
Posted: Fri Dec 19, 2025 7:47 pm
I am having trouble with my flow graph when trying to run an osmocom source and sink in the same flow graph using GNU radio companion 3.10.12.0 (Python 3.12.9). It is similar to https://nuand.com/forums/viewtopic.php?t=3058 .
I get the error:
Has anyone been able to run RX1 and TX2 simultaneously in the same flow graph? Any suggestions are appreciated.
I get the error:
Code: Select all
\Lib\site-packages\gnuradio\gr\top_block.py", line 116, in start
top_block_start_unlocked(self._impl, max_noutput_items)
RuntimeError: resolve_port: hierarchical block 'sink_impl': input 1 is not connected internally
