Make sure you set the Mb0 Subdev Spec parameter. Set it to ‘A:0’ to use radio A or ‘A:1’ to use radio B. Additionally, in the RF Options tab, make sure you select the antenna you’ll be using (TX/RX for TRX-A or TRX-B and RX2 for RX2-A or RX2-B. Trying to use RX1 will cause an error). If this doesn’t fix the issue for you, run uhd_usrp_probe from your host PC and share the output here.

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%7C6f6b366d1a7b46b737bb08dc3484e831%7Cbfc64a8d90644c6491c39d10b44c1cb6%7C0%7C0%7C638442992644460389%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C0%7C%7C%7C&sdata=GxoXIkSMgTIWDyvs0zxGCxj%2B8%2B0VdyvKFGbb7wDbiFc%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?
