fibaro-beacon-scanner/enterExit.js

Node.js beacon scanner based on noble that speaks to Fibaro

/*
  Continously scans for peripherals and prints out message when they enter/exit

    In range criteria:      RSSI < threshold
    Out of range criteria:  lastSeen > grace period

  based on code provided by: Mattias Ask (http://www.dittlof.com)
