Re: [Discuss-gnuradio] USRP1: Error: Connection refused

The 'connection refused' error is probably due to your firewall configuration blocking network broadcast probes which are sent for detection of ethernet connected USRPs. Try the following to force it to connect to the USRP1 type:

uhd_usrp_probe --args="type=usrp1"

Dear all,

I've reinstalled gnuradio 3.7.0 and UHD 003.007.001. Now I got this error when connecting USRP to my PC and running some commands:

1. sudo uhd_usrp_probe
Error:
linux; GNU C++ version 4.6.3; Boost_104601; UHD_003.007.001-release

Error: Connection refused

2. sudo uhd_find_devices
Error:
linux; GNU C++ version 4.6.3; Boost_104601; UHD_003.007.001-release


UHD Error:
    Device discovery error: Connection refused
--------------------------------------------------
-- UHD Device 0
--------------------------------------------------
Device Address:
    type: usrp1
    name:
    serial: 50a45bfc

How could I fix this?

Many Thanks,

Hoang
