Buffer sizes for UDPSink, UDPSource?

2019-11-08 Thread Jeff Kyser
Hi, I’m running gnuradio v3.7.13.5 under macOS Catalina. We’ve set up transmit and receive flow graphs for a simple BPSK system. We pass UDP messages which are received by a UDPSource at the start of the Rx flow graph, modulation is performed, and the carrier and symbols are sent to the Tx

I'll second what Marcus wrote about your GR being out of date. Using the latest GR37 or GR38 release would be a much better way to go if you can do so. I cloned your repo & had a heck of a time getting it to build. A few comments on the code itself first: * when you #include a GR header, it will

Hi Glen, You're welcome. It's a much needed area. I am including comments from Mike Piscopo via Slack #docs with his permission: I had an issue a year or two ago where my pybombs install got messed up between python2 and python3. I had to make sure it was removed with both pip and pip3,

Hi Christophe, it's indeed a bit surprising that in 2019, I still have to mention that, but: Please don't use GNU Radio 3.7.11 to develop new GNU Radio software; Ubuntu 18.04 is a bit behind the curve on development; the current release of the 3.7 series is 3.7.13.5, and we've really fixed a lot

Dear all I working under ubuntu 18.04 and GNURadio 3.7.11 and attempt to define a QTGUI eye_sink block to display eye pattern under gnuradio-companion. Without any knowledge of the best method to achieve this, I decided to: 1- define a new OOT module using gr_modtool     gr_modtool newmod

Hi Hans, I like that idea, but revision dates are a central feature of what a Wiki like ours offers: you can click on "Versions" and see when the current version was last edited. Sure, that might have just been a typo fix, but whether or not to update the "state of" written statement is still as

Re: [Discuss-gnuradio] cannot find block tree panel in grc
