PlutoSDR not recognized as a hardware device #68

Closed duggabe closed 4 years ago

duggabe commented 4 years ago

Ubuntu 18.04 Gnu Radio 3.8 GRC 3.8.0.0 branch: upgrade-3.8 When running a flowgraph with a PlutoSDR as the output device, I get the following warning: Generating: '/home/barry/RTTY_transmit/RTTY_Pluto.py'

Warning: This flow graph may not have flow control: no audio or RF hardware blocks found. Add a Misc->Throttle block to your flow graph to avoid CPU congestion.

It does work properly without the Throttle block.

tfcollins commented 4 years ago

The throttle flag is set correctly: https://github.com/analogdevicesinc/gr-iio/blob/upgrade-3.8/grc/iio_pluto_source.block.yml#L3

Can you provide the flowgraph?
