Hello,
Thanks for the info.
Also, I tried installing gnuradio and uhd from the build-gnuradio
script and "make failed"
I have attached the screen shot below.
Could you point me in the right direction?
Thanks
Looks like some code deep-down in the gr-fec tree isn't compiling on
your system.
You could have build-gnuradio pull from "master":
build-gnuradio -m -v
And see if that changes anything.

Hello,
I was trying to ping usrp b200mini at 192.168.10.2 from the host
computer but there is no repsonse from the device.
--- 192.168.10.2 ping statistics ---
17 packets transmitted, 0 received, 100% packet loss, time 16365ms
What could be the issue?
Thanks
The issue is that the B2xxx (and, indeed, all of the USB-connected
USRPs) are not network-connected devices. They don't have an IP
address--
they don't speak IP. They're connected over USB, not ethernet.

Yes, I will refer that.
I am trying to decode the P25 signal using b200mini on
ubuntu 16.04 using gnuradio.
I have the P25 receiver(demodulator + receiver) open source
code compiled and running but how do I make it work
with usrp b200mini?
How would I go about that?
I'm sorry if I am vague but I am ready to provide additional
details.
Thanks
There's probably an e-mail list devoted specifically to that
software--you might try there.

This shows up when I run uhd_find_devices

In your case:

Will work, but I suggest spending some time with the
online UHD manual, and the Ettus Knowledge base:

Both Gnuradio and UHD support was build from

up but I am not able to run the flow graph?
What does "not able to run the flow-graph" mean,
precisely? We can only help you if we have details
and "it doesn't work" is too hand-wavy
to provide adequate assistance.
Does GNURadio companion identify the device?
What do you mean by "identify the device".
There's a "device address" field in any UHD
source/sink. It must be filled out to tell it what
UHD device you'd like your flow-graph to talk
to. You could have more than one on a system, and
there are many different types of
USRP devices. UHD (and by inference, Gnu Radio)
has no way of knowing what your intention is. You
have to tell it.

Hey guys,
I am fairly new to gnuradio companion but
I was trying to use the UHD: USRP source
block in the environment with my usrp
b200mini but it does not show up.
How do I verify this?
What do I need to put in the device address?
-> uhd_find_devices and uhd_usrp_probe are
able to load the image and the device
correctly.
Thanks in advance.
You mean the block doesn't show up in Gnu Radio?
If so, that means your local instance of Gnu
Radio was built without UHD support. How was
it built?
