Thanks for adding "gain control mode option" a few weeks ago. However, I'm having trouble using it.

Any ideas what may be the issue? I would expect the "Gain" (numeric) text field in Pluto Receive and Reconstruct block to disappear when "Gain control mode" field is anything other than "manual". Maybe it's related to this.

Manual gain mode works fine though. Other options: fast_attack, slow_attack, and hybrid AGC all result in this error. I don't think it's a hardware problem since the AGC feature works with default firmware using PlutoSDR source.

Thanks for your detailed report. I updated the block YAML files in the master branch so that the generated code will only set the gain value if the gain control mode is manual. Similarly, the gain field in the user interface now only appears if the gain control mode is manual. That should match what the Pluto source block from gr-iio does.

Let me know if the new version works.

Thank you for a quick fix! It works now!
