LimeSDR - Mini on Ubuntu with GQRX
Getting the new LimeSDR Mini working on Ubuntu with GQRX was a bit challenging. These are the rough steps
- Install LimeSuite
- Install udev-rules
- run GQRX with sudo (I've since noticed this doesn't seem to be mandatory.)
- Run GQRX as "other" with device string as "driver=lime,soapy=0"
- Set bandwidth to 20 MHz and input rate to 2.5 Msps
- Set antenna to LNAW
Install Limesuite as follows:
sudo add-apt-repository -y ppa:myriadrf/drivers sudo apt-get update sudo apt-get install limesuite liblimesuite-dev limesuite-udev limesuite-images sudo apt-get install soapysdr soapysdr-module-lms7
Install GQRX as follows:
sudo apt-get purge --auto-remove gqrx sudo apt-get purge --auto-remove gqrx-sdr sudo apt-get purge --auto-remove libgnuradio* sudo add-apt-repository -y ppa:bladerf/bladerf sudo add-apt-repository -y ppa:myriadrf/gnuradio sudo add-apt-repository -y ppa:gqrx/gqrx-sdr sudo apt-get update sudo apt-get install gqrx-sdr
Download udev-rules and install OR build LimeSuite from source. Although i have downloaded the source I am ONLY installing the udev-rules.
https://github.com/myriadrf/LimeSuite.git cd LimeSuite.git cd dev-rules sudo chmod +x install.sh ./install.sh
Start GQRX as sudo. Your LimeSDR-Mini should start flashing its LED green wildly about now. That means GO!
Set up as follows:
For some odd reason if you remove the dongle and re-install it, it may or may not work again. If you do manage to try everything like 10 times and get it to load again every single time you will have to set the Antenna and Hardware AGC. Very odd behavior. The driver is still wonky. And my directions here are not foolproof. Sometimes it works, sometimes it doesn't. I've found myself having to open LimeSuite and connect to the LimeSDR-mini and hitting Default and disconnecting. Not sure if that does something or not. Again as I stated above I've noticed that GQRX doesn't have to be run as sudo. I have found that sometimes all is well the first time you run GQRX and other times you have to open and close the program multiple times before the driver loads correctly.
