   OpenThread.begin(true) will automatically start a node in a Thread Network
   Full scanning requires the thread node to be at least in Child state.

   This will scan the IEEE 802.14.5 devices in the local area using CLI "scan" command
   As soon as this device turns into a Child, Router or Leader, it will be able to
   scan for Local Thread Networks as well.
