Pluto drivers with Ubuntu 20.04 & GNURadio 3.8

    HI,

    I try to install drivers for Pluto at Ubuntu 20.04 and GNURadio 3.8 without success. I can not see them inside the GNURadio. I add export PYTHONPATH=$PYTHONPATH:/usr/local/lib/python3/dist-packages which is the directory contaning iio without success. Also I put export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH.

    Any help ?

    Hi,

    Finally I rollback as drivers are not ready yet for most devices. I will like to use Python3 for GNURadio but ...

    Hallo George ...


    installed Ubuntu20.04 now on my Linux machine.... Pluto wit IIO-Oscillocope worked ok and and modules compiled like given in the info from analog devices ....


    BUT:

    I cannot get running Pluto with Gnuradio 3.8.1.... IIO and Pluto block are inside GRC

    getting an error when starting the simple flowgraph... something si missing i think...


    this did not help .... export PYTHONPATH=$PYTHONPATH:/usr/lib/python3/dist-packages

    Hallo ...


    after some recherche in the WEB the Pluto is running now...with upto 60MHZ BW in Spektrum mode (-no decode mode) ...

    (decode of signlas is only possible with lower samplerate and BW < 5MHz because of USB2.0)


    the solution:

    you have to put in the following line in your .bashrc file


    export PYTHONPATH=$PYTONPATH:/usr/local/lib/python3/dist-packages


    after then you can start the gnuradio-companion from terminal.


    (It looks it is a bug in Gnuradio 3.8.1 or later and will maybe solved in the future)

    Hallo ...

    made an other screenshot this morning from the "simple pluto analyzer" with 10MSPs on GNURADIO 3.8.1 Ubuntu 20.04


    RX: 80cm DISH, LNB-LO 9.388 MHz (TCXO) H-pol, IF 1105 in CENTER, AVERAGE and MAXHOLD ....


    you can nicely see the sigs of both transponders , NB is relatively weak because of polarisation loss V->H


    So the next time not to much time anymore ... "playing a bit"
