  <p>What is the best way hardware to interface both ? 
  via UART ? </p>
  
  <p>Could you provide the hardware link and the way for testing ? </p>
  
  <p>Software side I would like to use python 3 language to interface both.      </p>
  
  <p>Can you provide the code example ?</p>
  
  <p>Thanks</p>
