Re: [USRP-users] Re: N321 LO sharing between RF 0/1

Ok, so I tried setting the LO distro from a python interactive shell. The lights come on. Then I disconnect from the terminal. The lights stay on. Next I start my flowgraph with the rest of the configuration options (LOs set to export, timing ref, etc). When the flowgraph runs, the LO output lights

Re: [USRP-users] Re: N321 LO sharing between RF 0/1

Hi Paul, Would this work if you run these calls before the gr-uhd code in the flowgraph instances the device? This can be tested by inserting the code manually. It could be a solution, but I'm not even sure if you can insert a Python snippet in that location. However, if gr-uhd resets these s

Hi Elmore - those are system errors - not gnuradio errors. How did you get from jessie to bullseye? Did you consult anyone on the Debian mailing lists on how to proceed? It's standard practice to backup anything you can't afford to loose when upgrading an operating system. And it's possible

Marcus, At your suggestion: I upgraded to Debian 11 (Bullseye) following instructions I found on Tom’s Hardware site. It seemed to be successful except that GNU radio no longer executes. Figuring that perhaps I need to install Debian 12 and upgrade to GNU radio 3.9 before it will run again I w

Thanks Jeff I was actually going down the tags road already. Since JAERO doesn’t use GNURadio, if I am going to modify JAERO to read tags, I’d like to do it in the cleanest way possible so I can have a simple feature/pull request and not require GNURadio as a dependency. That being said, can yo

Re: send 2 key/values with ZMQ PUB sink

No, the current code will only add the key (topic) to each message. Tags are passed through ZMQ, so you could inject tags (this might require a custom block) periodically and receive them in JAERO. You probably don't want them in every message anyway. This means that the receiver will need to wait
