Python: Check if a string is a valid float

isfloat() function

def isfloat(value):
  try:
    float(value)
    return True
  except ValueError:
    return False

Use:
if(isfloat(arduinoString)):
        data = float(arduinoString)
        dataArray.append(arduinoString)
        index=index+1

HackRF with srsLTE and openlte

HackRF with srsLTE srsLTE supports USRP, bladeRF and SoapySDR. HackRF is interfaced to srsLTE via SoapySDR. 1)First build srsLTE 2)Install SoapySDR and test SoapySDR to detect HackRF One Follow link here: https://github.com/pothosware/SoapyHackRF/wiki Dependencies Install libhackrf - https://github.com/mossmann/hackrf/wiki Install SoapySDR: https://github.com/pothosware/SoapySDR/wiki Or install Hack RF packages on Ubuntu: I have followed this procedure: sudo add-apt-repository -y ppa:myriadrf/drivers sudo apt-get update sudo apt-get install hackrf libhackrf-dev Building Soapy Hack RF The CMake build system will locate libhackrf and SoapySDR development files on your system. The plugin module will be built and installed into the SoapySDR modules directories. git clone https://github.com/pothosware/SoapyHackRF.git cd SoapyHackRF mkdir build cd build cmake .. make sudo make install Probing Soapy Hack RF SoapySDRUtil --probe=...
