Yes, I am trying to run the E312 in host mode. Here are the parameter settings I currently have in the General tab of the block properties:
* ID – uhd_usrp_source_0 * Output Type – Complex float32 * Wire Format – Automatic * Stream args – * Stream channels – [] * Device Address – addr=169.254.7.165 (auto-assigned IP) * Device Arguments – * Sync – No Sync * Start Time (seconds) - -1.0 * Clock Rate (Hz) – Default * Num Mboards – 1 * Mb0: Clock Source – Default * Mb0: Time Source – Default * Mb0: Subdev Spec – * Num Channels – 1 * Samp rate (Sps) – samp_rate (variable) From: White, Joshua J <jjwh...@riversideresearch.org> Sent: Friday, February 23, 2024 09:09 To: Kunnappally, Jerry J. <kunnappally.ja...@mayo.edu>; Jack Ferrell <jackferr...@ieee.org> Cc: discuss-gnuradio@gnu.org Subject: [EXTERNAL] RE: Re: USRP E312 host mode error It is possible to run the E312 in host mode (if I understand correctly, this is what you’re trying to accomplish).

You can then send whatever data to your laptop using ZMQ blocks to publish data from the radio and receive data on the laptop, which will be running its own flowgraph. A good example is shown here: https://kb.ettus.com/Streaming_processed_data_from_the_E31x_with_GNU_Radio_and_ZMQ<https://usg02.safelinks.protection.office365.us/?url=https%3A%2F%2Fkb.ettus.com%2FStreaming_processed_data_from_the_E31x_with_GNU_Radio_and_ZMQ&data=05%7C02%7Cjjwhite%40riversideresearch.org%7Cd3516063fd5b4fcfb8fd08dc33edcf0b%7Cbfc64a8d90644c6491c39d10b44c1cb6%7C0%7C0%7C638442343692269130%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C0%7C%7C%7C&sdata=3Uj%2FWZgboUXPRIbfl8xoGvuygiIxjLXm2eOkuiVmCSE%3D&reserved=0> Hope this helps. - Jack On Feb 22, 2024, at 15:30, Kunnappally, Jerry J. via GNU Radio, the Free & Open-Source Toolkit for Software Radio <discuss-gnuradio@gnu.org<mailto:discuss-gnuradio@gnu.org>> wrote: Hello, I’m currently trying to interface with a USRP E312 over Ethernet using an Ubuntu laptop running GNURadio (via radioconda). When I enter the address for the device in the USRP Source block in GNURadio and run the flowgraph, I get the following error in the console: ``` self.uhd_usrp_source_0 = uhd.usrp_source( ^^^^^^^^^^^^^^^^ RuntimeError: RuntimeError: [multi_usrp] No radios found in the requested mboard: 0 >>> Done (return code 1) ``` I seem to be finding the device okay, so I think it’s a configuration thing in the USRP Source block. I’ve looked all over for hardware info so that I can enter in the right config parameters in to the block, but to no avail. Could I get some help configuring the block to get around this error? Thanks, Jerry Kunnappally
