Hi,
I have created a simple tcp based iq stream using ZMQ blocks to use a HackRF remotely over an ethernet network.
I have a linux computer (Raspberry Pi) connected to the HackRF running GNURadio. The HackRF source is connected to a ZMQ sink that transmits the packets to a receiving linux PC running GNURadio - where a ZMQ source connected to a QT sink for visualising the IQ signal stream.
This works fine for a fixed frequency, sample rate and fft size etc, however my problem is that i want to be able to change those parameters from the receiving PC.
Despite much research, i have been unable to find a way to change the parameters of the remote flowgraph (client) from the receiving display end (server).
Is there a way to natively perform this operation within GNURadio and can someone provide guidance on how to setup a flowgraph to achieve this? Or is there some additional OOT block or custom python block i would need to create to do this.
Thanks
Alex
