Re: Gnuradio-companion as a network relay

[Anish Mangal]

Thanks, I tried a very basic example and was trying to monitor data rate using nethogs with a different sample rate.

At a signal sample rate of 9.6MSPS, nethogs sees about 59MB/s of data. I wonder if that could be improved in anyway, or whether the sample rate of an actual wired lan connection might be better?

I vaguely remember that the USB data transfer rate at 6.4MSPS was about 15MB/s.

I try to show at https://www.youtube.com/watch?v=M8dqgqO4TuI starting
at 9:30 how to stream data from GNU Radio using ZeroMQ
publish/subscribe, in my case to external Python software which could
very well be remote if the IP address is not 127.0.0.1, but will be
even easier to implement if the client is another GNU Radio flowchart.
I am currently doing exactly that: recording on a Raspberry Pi and
streaming to a more powerful computer for processing (again from a
dedicated Python script rather than another GNU Radio instance, e.g
around 45 min of that video).

Best, JM
