Hi!
The flowgraph execution failed and the relevant error output seems to be RuntimeError: device_id missing.. The error message is quite hard to read due the excess of unnecessary information.
Previously this error was reported here. It can be caused by a bad/no USB connection to the SDR.
addendum: I just opened satnogs-flowgraphs#42 to track a possible future improvement of the log output. This is not prioritized now, but shouldn’t be lost either.
