Re: [Discuss-gnuradio] [USRP-users] Using ZMQ

[Derek Kozel]

Hello Steve,

Please keep the mailing list included unless you are talking about something which requires privacy. GNU Radio runs natively on Windows. It is not as well supported from an end developer stand point, but it is available and with a bit of work can be a very viable answer.

Hi Derek,

I am unfamiliar with such functionality:

How can I run a full gnuradio flow graph via windows?

Thanks,

Steve

Hello Steve,

Can you directly use the X310 from the Windows PC? UHD is fully supported on Windows 7 to 10.

Regards,

Derek

Thanks Marcus, I got it to work just fine.

Your remark is a little concerning... is there any more efficient way to send data over the internet?

Furthermore, I actually don't necessarily need to pass the samples over the internet. I simply need to send the samples directly from the X310 to a windows PC at high rate (Employer's demands, non-negotiable). 

Is there any way to get around this problem? for instance, instead of the internet to construct some communication box? I've never dealt with such things before....

Thanks again,

Steve

Hi Steve,

That's a pretty network-centric question!

So, first of all, you need to make sure you can actually send IP packets from one computer to the other - that will require figuring out the public IP address of the server end of the connection, making sure the firewall on that computer allows for connections to that port, and also make sure that if any routers are in between (especially if they do NAT/masquerading), that these will forward the packets.

As a side remark: even the lowest sample rate possible on an X310, which is 195.3125 kS/s, will require that the sending end has more than 6.25 Mb/s of continuously available uplink. That is actually not that little, so unprocessed samples are seldom what you'd want to send over the internet!

Best regards,
Marcus

Hi all,

Disclaimer: I have never used zmq before.

My goal is to control a X310 from a remote PC, and receive data. using ZMQ.

I downloaded the simple example zmq_stream.grc: https://github.com/gnuradio/gnuradio/blob/master/gr-zeromq/examples/zmq_stream.grc 

I ran the flow-graph on two different pc's, both connected to the web. The first pc had the PUB/PUSH/REP blocks, while the second had the SUB/PULL/REQ blocks. Quite frankly, the signal hasn't reached the second pc.

How do I ensure both pc's are subscribed one to another?

Anything else I got wrong?

TIA,

Steve
