Hi,
I am interested in implementing a relatively simple repeater application on
the X310 and E310. I ran the Ettus rfnoc_radio_loopback example and this is
nearly a perfect fit for the functionality I want. However, I am wondering
how my application can intelligently set the Rx Gain & Tx Gain. Actu
Dear Community,
I am facing an issue with UHD 3.15.0 and USRP N310 since, sometimes, the
application (OAI gNB) does not start and returns this error:
[ERROR] [UHD] Exception caught in safe-call.
in ctrl_iface_impl<_endianness>::~ctrl_iface_impl() [with
uhd::endianness_t _endianness = uhd::END
Hey Rob:
If you use GNURadio, The probe signal block can take in a stream and the
function probe block can poll The level on a time interval that you set in the
block. Then you can use that changing variable elsewhere in the flowgraph to
adjust the gain.

Thanks Paul,
After re-reading my original email, it was a bit misleading. The streaming
samples are never coming to the host - they are just looped from Rx to Tx
on the FPGA. Thus, I can't determine the digital power on the host. I'm
guessing that the probe signal block you mentioned operates on
Oh ok, yes. I was a bit confused when I read it, but Now I understand. Yes you
would have to have sample streaming to the host. I believe the FFT block has a
magnitude output that you could query. It’s been a while since I looked at the
code, but it was talked about at GRcon last year as a good
