  Most STM and Freescale ARM chips include a unique Serail Number embedded
  in the CPU.  This is a perfect number to use in IoT as a SSID.  I use
  this to produce the WIFi SID so I can walk up with a phone and download
  telemetry.   I found a blog discussion for mbed that suggested using the
  MAC but this assumes mbed hardware whereas this version uses the serial
  number built in to the CPU so it should work on native boards.
