Callback method not being provided in GR 3.10 OOT Block

Selecting a SDR as a sink

Asked this on chat, thought it might need a broader audience so am asking here too... Part of my flowgraph looks like: I.e. a selector that selects between output to null sink, osmocom sink or PlutoSDR sink. Problem is when I run the flow and no SDR is present (I select Null Sink by defau

Using VSCode With gr-tutorial
