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 released, I created a new environment with UHD 4.0
and Gnuradio 3.8 installed. So do I need to update Gnuradio to 3.9?

TBH, I'm not sure which versions of gr-uhd will prompt the message, that
is coming from the UHD library.
But, like I said, it's just a *WARNING*. Things will still work just
fine. It's basically saying the "in the future, this will stop working".
I'll note that in my current code base (GR 3.8.2,
55621a9709b219551b908e67ee88f6f7ad2593cb) the recv_async_msg() call is
still tied
to the underlying multi_usrp device, and NOT the streamer.
Perhaps the current maintainer of gr-uhd can comment on whether this is
fixed in a subsequent gr-uhd version (after GR 3.8.2)

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
this message.

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

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?

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 I have not had any luck finding the file I need to
edit. Can anyone direct me on how to solve this problem?
Best Regards,
Jerrid Plymale
