I'm trying to run the Ettus N300 on GNU radio.
When I'm running GNU radio via: pybombs run gnuradio-companion, I get the following error when trying to run the USRP Source block:
[INFO] [UHD] linux; GNU C++ version 7.5.0; Boost_106501; UHD_3.15.0.0-62-g7a3f1516

RuntimeError: rpc::timeout: Timeout of 2000ms while calling RPC function 'get_num_xbars'
Note that uhd_usrp_probe works without warnings and also the UHD example:
/usr/local/lib/uhd/examples/rx_ascii_art_dft --args
"master_clock_rate=125e6,mgmt_addr=192.168.1.151,addr=192.168.10.2"
--freq 98.5e6 --rate 2.5e6 --gain 50 --ref-lvl="-50" --dyn-rng 90 --ant
"RX2" --subdev "A:0", runs like a charm.
Anyone knows how to fix this?
Thanks in advance
