Hello,

I’m trying to get my LimeSdrMini2.0 up and running with GnuRadio3.10.

I’ve done all the installation steps describe on myriadrf and GnuRadio.

Here are the installation sequence  (I omit sudo):

Name	Command	Version
Ubuntu	Fresh from ISO image and all updates	22_10 64Bit (kinetic)
GnuRadio	apt install gnuradio	3.10.3.0
swig	apt-get -y install swig	4.0.2-1
boost	apt-get install libboost-all-dev	1.74.0.3
git	apt-get install git	1:2.37.2-1
g++	was already installed with ubuntu	4:12.2.0-1
cmake	apt-get install cmake	3.24.2-1
sqlite3	apt-get install libsqlite3-dev	3.39.3-1
soapysdr	apt-get install libsoapysdr-dev	0.8.1-2
i2c	apt-get install libi2c-dev	4.3-2
usb	apt-get install libusb-1.0-0-dev	2:1.0.26-1
wxgtk	apt-get install libwxgtk3.0-gtk3-dev	3.0.5.1+dfsg-4
freeglut	apt-get install freeglut3-dev	2.8.1-6
LimeSuite	From source git clone https://github.com/myriadrf/LimeSute.git	20.10.0+dfsg-6
gr-limesdr	From source git clone https://github.com/bkerler/gr-limesdr	3.0.1-4

(LimeUtil, LimeQuickTest, LimeSuiteGUI runs well)

 

And here is my question/problem:

On GnuRadioCompanion I have a very smal flowgraph(SampRate=1MHz):

LimeSuiteSource(RX) --> QT_GUI Frequency Sink

 

On startup it give me the following output:

Generating: '/home/user/MyTest_2.py'

Executing: /usr/bin/python3 -u /home/user/MyTest_2.py

Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome.

Use QT_QPA_PLATFORM=wayland to run on Wayland anyway.

This looks like ok, but the samples in the QT_GUI Frequency Sink have all

0(zero) amplitudes. The sampRate 1e6=1us(steamPlot) is correct.

I don’t now what goes wrong in this configuration/setup.

Has anybody experience with LimeSdrMini2.0 as frontend to GnuRadio?
