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
System Implementation 1)Function in Android 2) Display on Pebble Pebble Smart watch Page 17
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
Conclusion 2) Bluetooth: • Meet the system requirement • Communication range • Low cost • Convenient for future development • compatibility Page 19
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
