Re: [Discuss-gnuradio] Help required for tunnel.py with two USRPs

[Derek Kozel]

Hello Henning,

To make it easy to update UHD versions Ettus has a private package archive, PPA, for Ubuntu. You can update your UHD using the following commands. You will still need to recompile GNU Radio (most accurately gr-uhd) to make it compatible with the newer UHD's interface.

# Remove existing packages

sudo apt-get remove uhd libuhd003 libuhd-host libuhd-dev

# Install the new repository, update package lists, and install the up to date versions

sudo apt-add-repository ppa:ettusresearch/uhd

sudo apt-get update

sudo apt-get install libuhd003 libuhd-host libuhd-dev

# Check installed uhd version, it will be on the first line of the output. It should read release 3.9.2

uhd_find_devices

Regards,

Derek

The UHD you're using is 3.5.5. That is much older than the B200, so this
can't work. You will have to use a newer version of UHD, then re-compile
GNU Radio to work with that, and then try again.

I presume you installed UHD and GNU Radio through your Linux Distro's
package manager? (Guessing from the version, that's Ubuntu 14.04? If
that's the case, I'd recommend getting something newer.)
Please uninstall the uhd, libuhd, libuhd-host, libuhd003-devel packages
(however they are named on your system) and the gnuradio package, before
installing newer versions manually.

There's tools to help you with that!

Best regards,
Marcus
