Install bladerf-firmware-fx3 by entering the following commands in the terminal:

nuand bladeRF firmware downloader (FX3)
This empty package will, at the time of installation, download an appropriate firmware image for using the nuand bladeRF with a Cypress FX3 USB controller. The image will be downloaded from http://nuand.com/fx3/ and saved to /usr/share/Nuand/bladeRF. . This bitstream will work for either the nuand bladeRF x40 or the x115. . Note that this will not upgrade the bladeRF itself. That can be done with the bladeRF-cli utility.
