  9. Software Design Focus part System Architecture Page 9

  10. Software Design • Purpose: • Storage of following information: • User Information • Sensor Status • Read Value and Time Database Design Page 10

  11. System Implementation Desktop Application Serial Connection serialPort = (SerialPort) portId.open("Ardunio", 2000); ArdunioControl reader = new ArdunioControl(); publicvoid serialEvent(SerialPortEvent event) Connection and Query of Database Class.forName("sun.jdbc.odbc.JdbcOdbcDriver"); Connection con=DriverManager.getConnection(url,user,password); Statement stmt=con.createStatement(); ResultSet result=stmt.executeQuery(ls); Java GUI Page 11

  12. System Implementation Desktop Application 1)Main Page Page 12

  13. System Implementation • Desktop Application 2)Read and Query Data Page 13

  14. System Implementation 1)Main Page 2)Searching Device 3)Read Data Android Application Page 14

  15. System Implementation Original Plan: Two Slave devices cannot be paired Implementation: Using Android as a bridge for transmission Pebble Smart Watch Page 15

  16. System Implementation Pebble Smart Watch Message format Example: //content of message: “connected” const uint8_t connectedMsg[30]={0x00, 0x1a, 0x0b, 0xB8, 0x01, 0x00,0x09,0x43, 0x6f, 0x6e, 0x6e , 0x65, 0x63, 0x74, 0x65, 0x64 , 0x0d ,0xFF, 0xFF, 0xFF, 0xFF , 0xFF , 0xFF, 0xFF, 0xFF , 0xFF, 0xFF , 0xFF , 0xFF, 0xFF}; Yellow part: These 6 numbers are fixed for every message. Green part: This hex number is the number of the char included in this message. Blue part: The sequence of hex number is obtained by transform the content of the message into hex format. Red part: The rest of the message packet is filled with “0xFF”, in order to reach 30 hex numbers in each message packet. Page 16

  17. System Implementation 1)Function in Android 2) Display on Pebble Pebble Smart watch Page 17

  18. Conclusion 1) Arduino: • Excellent choice for conducting this project. • Completed Library and easy language • Plug and play Feature • Great potential for development of medical system • Low cost • Good extensibility Page 18

  19. Conclusion 2) Bluetooth: • Meet the system requirement • Communication range • Low cost • Convenient for future development • compatibility Page 19

  20. Conclusion 3) Java: • not an appropriate language for serial communication • Input stream reading: • Byte hex • Better to combine with other language such as C. • Good in development of interface and multimedia Page 20
