Begin continuous acquisition.

With background=True the daemon runs fetch_iq in a loop, which the blocking fetch paces, so blocks publish without a loop of your own.

Parameters:

  • direction (Direction) – Signal path, Direction.RX or Direction.TX.

  • channels (Sequence[str]) – Channels the stream covers.

  • background (bool) – Hand the fetch loop to the background daemon.

  • n_samples (int) – Samples per channel per block, when background is set.

  • publish_spectrum (bool) – Also publish spectrum features for each block, when background is set.
