Re: [Discuss-gnuradio] Bursty transmission in GNURadio 3.7.13.4

[Jiaxin Liang]

Hi Martin,

We are using the X310 USRPs, and each of them has two channels. The
configurations for those two channels are the same except for the center
frequency (kind of like an FDMA system).

Best regards,
Jonathan

[Discuss-gnuradio] Bursty transmission in GNURadio 3.7.13.4

[Jiaxin Liang]

Hi,

I have been using the bursty transmission (see here
)
in GNURadio for USRP transmission for a while. And we have a stable program
running on GNURadio 3.7.10.2 with UHD 3.9.7.

Recently, we are trying to upgrade the GNURadio to 3.7.13.4 and the UHD to
3.15.0 (rfnoc version). But we kept receiving "L" from the very beginning
to the end.

May I ask whether the bursty transmission is still available in the above
version? If yes, is there any changes I should notice?

Best regards,
Jonathan

Re: [Discuss-gnuradio] RX error code in UHD

[Jiaxin Liang]

Hi Marcus,

Thanks for your prompt reply. Regarding the newer version of UHD, are there
any recommended versions of the UHD that can drive the X310 stably?

Best,
Jonathan

[Discuss-gnuradio] RX error code in UHD

[Jiaxin Liang]

Dear all,

I'm working on the MIMO using the USRP X310 and try to build a transceiver
in GNURadio for pinot-to-point communication. However, sometimes when I run
the program, the UHD will give me the following WARNING:

*USRP Source Block caught rx error code: 2*

After we saw this line, the program just completely hanging with some "L"
shows. We have to terminate the program and restart it. Our Linux version
is 16.04 and the UHD version is 3.9.5.

Are there any suggestions or clues to solve this issue?

Many thanks in advance!

Best,
Jonathan
