Subject: LimeSdrMini2.0, GnuRadio3.10, Ubuntu22_10(kinetic)
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. --------------------------------------------------------------- LimeSuite Source (RX) info ################## Connecting to device ################## LimeSuite version: 22.09.1-gabc28c0e gr-limesdr version: 2.2.7 ################## Device list: Nr.:0 device:LimeSDR Mini, media=USB 3.0, module=FT601, addr=24607:1027, serial=1D90F5631A4C83 ################## Reference clock 40,00 MHz Using device: LimeSDR-Mini_v2(1D90F5631A4C83) GW: 2.1 FW: 8 ################## INFO: device_handler::enable_channels(): SISO CH0 set for device number 0.

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? Karlheinz
