Ok, so what you're saying is I need to update Gnuradio to a newer version? The way I have my software setup is everything is installed into virtual environments. So when I initially started using the USRP, I created an environment that had UHD 3.15 and Gnuradio 3.8 installed. When I saw UHD 4.0

[USRP-users] Re: Where do I find this call to change it.

ok so this is likely a case of your gr-UHD assuming an older API for recv_async_msg. This is just a warning that eventually that older API will go away. Probably if you had totally up to date everything, or a UHD library that was of an earlier vintage that matched he-UHD, yiu wouldn’t get thi

Hello Marcus, This is coming from a Gnuradio flowgraph that I created myself. It’s got USRP Rx and Tx blocks, a block that takes samples of the signal and preforms some DSP, and a bunch of GUI variable control and variable display blocks. Best Regards, Jerrid From: Marcus D Leech Sent: Frida

I think we need more context. Is this from a program you write yourself? Someone else’s code? A Gnuradio flow graph? Your own? Someone else’s? Sent from my iPhone > On Mar 12, 2021, at 3:02 PM, Jerrid Plymale > wrote: > >  > Hello All, > > Here is the warning message I am trying to so

Hello All, Here is the warning message I am trying to solve: [WARNING] [MULTI_USRP] Calling multi_usrp::recv_async_msg() is deprecated and can lead to unexpected behaviour. Prefer calling tx_stream::recv_async_msg(). I am trying to solve this warning message when I am running my USRP X310, but

This device loads its FPGA image whenever it has been power cycled and you start a session with it. The Images would be in the data files associated with your UHD installation. You cannot establish a session with it unless there’s a functional FPgA image loaded and running. Sent from my iP

[USRP-users] Re: Why TRX port has 20+ dB more loss than RX port for received signals?

Hey Arnold, What test frequency are you using to compare the received power at these two ports? I pulled up the schematic for the E310's daughterboard , and took a look at the signal path for TRX (J4) vs RX (J3): [image: image.png] For the RX

[USRP-users] USRP E320

Hi everyone, We are starting a project and we want to buy a batch of E320s and our goal is to run Openaireinterface 5G on them. These cellular communication softwares like Openaireinterface and srsLTE they recommend USRP devices such as B210 or X310 and not E320. I wanted to ask if anyone has t

[USRP-users] Why TRX port has 20+ dB more loss than RX port for received signals?

Hi, We are implementing a TDD system and using the TRX-A port in lab testing. To facilitate TX/RX switch, we built control logic to control the GPIO pin to flip SW1 on Page 7 of the published E310 daughter board schematics. What we noticed are: 1. The RX ports cannot be cut off, so we must di

Is there any chance that your code is attempting to set the master clock rate? If so, perhaps see what happens if you don't set it in order to let it be set automatically. On Fri, Mar 12, 2021 at 8:55 AM Oliver Towlson wrote: > Hi everyone > > > > Thanks so much for your quick responses. Seems

Hi, I was looking at release 4.0.0 of UHD. We are tracking a list of outstanding issues with UHD/USRP radios and were wondering if any of these issues have been addressed in recent releases of the software. I attempted to find the original mailing list posts for each of these tickets but the se

Hi everyone Thanks so much for your quick responses. Seems like the thing we were missing was that subdev spec - once that was set it was straightforward to generate the code. We tried running it and got the following: [INFO] [UHD] linux; GNU C++ version 9.2.1 20200304; Boost_107100; UHD_3.15
