    • 115200 baud rate
    • 8 bits of data
    • No parity
    • 1 stop bit
    • No flow control
  3. Start the application.
  4. In the terminal window, the following text should appear:
         -- Low_power Example xxx --
         -- xxxxxx-xx
         -- Compiled: xxx xx xxxx xx:xx:xx --
    
  5. Press one of the keys listed in the menu to perform the corresponding action.
