+/* xej-Nucleo-F401RE-and-HC05-Bluetooth.cpp
+  Test Nucleo-F401RE with HC05 Bluetooth adapter
+  
+  Wanted to use it for upload of telemetry
+  type a command and hc053 port and it will be echoed back
+  
+  
+  pin-HC05  Pin-MBed
+   TX   --- PA_12
+   RX   --- PA_11
+   +5V  --- +5 on CN6
+               Also worked on 3.3V on CN6
+   GND  --- GND on CN6
+   STATE--- NC - not connected
+   EN   --- NC - not connected
+  
+   If you cycle power on mbed you may need to close 
+   and re-open the port connection which
+   is pretty easy when using RealTerm.
