re 2-:
Your `recv` call fills in a metadata object, which has a `timespec` member. You could use
that. I've hacked together debugging receivers in the past where I just wrote the
timespecs and the samples they belong to interleaved to a separate file, something like

Hi Rob,
RFNoC_Replay as you mentioned is great without any underrun even with higher
sample rate.
1- I have a same radar application and I implemented the TX/RX code with two
methods in GNU Radio: with RFNoC_Replay and also with simple USRP sink/source
blocks.

Hi Marcus,
After a bit more testing, I am increasingly convinced that the application
begins to hang only after encountering a late command error for the first time.
If this is indeed the case, the time it takes from start of application to
hanging depends on the number of samples transmitted/r
One more thing. One difference between 3.15 and 4.xx might be the length
of FIFOs on the FPGA for buffering Tx data arriving from the host. If the
4.xx buffers are smaller, then it may be more likely for a "glitch" to
occur if your host is a bit "bursty" when providing the samples. If this

Hi Anna,
I do not have a response to your direct question regarding performance.
However, I have a suggestion that may make the performance irrelevant.
The X310 image comes with a Replay block that accesses the DRAM chip for
storage. Given that you are sending a repeatable waveform, you should ha
Hello Ms. Broome,
that does sound complicated and undesirable. From the top of my head, I have no idea what
could cause this. Barring any method of directly debug this – how quickly does
reproduction for you work? Meaning, from the start of your application to the application
