It can be used to drive the HackRF and the LimeSDR among others. Required dependencies that need to be installed are, in order: 1. SoapySDR itself from https://github.com/pothosware/SoapySDR -1. The LimeSuite for the LimeSDR from https://github.com/myriadrf/LimeSuite -1. HackRF support for SoapySDR from https://github.com/pothosware/SoapyHackRF +2.
