title: HC-12 detection by Raspberry Pi bluetooth scanner
body: <p>I have bought an HC-12 module, but as much as I have investigated I have not found a way that a Raspberry Pi with a bluetooth detector called bluelog can detect it.</p>
  <p>What do I have to do so that HC-12 wired to a Arduino can be detected with the bluetooth scanner?</p>
  <p>How to set HC-12 in 'discoverable' mode?</p>
  <p>Thank you</p>
