通过蓝牙插槽写入输出流

Question

我有这个 -

char[] uploadCommand2 =  {0x7d, 0x4d, 0x01, 0x00, 0x01, 0xcb};

所以我可以使用它 -

 //writing to outputstream
for(int k=0; k < uploadCommand2.length; k++){
try {
    new DataOutputStream(socket.getOutputStream()).writeByte(uploadCommand2[k]);
} catch (IOException e) {
    e.printStackTrace();
}
}

但是现在我有了这个 -

String numberthYear = "0x" + decodeDecToHex(numberOfYears); //Evaluate to 0x0E

String dayYear1 = "0x" + dayYear.substring(0, 2); //Evaluate to 0x01

String dayYear2 = "0x" + dayYear.substring(2, 4); //Evaluate to 0x11

String hour =    "0x" + decodeDecToHex(now.get(Calendar.HOUR_OF_DAY)); //Evaluate to 0x0D

String minute = "0x" + decodeDecToHex(now.get(Calendar.MINUTE)); //Evaluate to 0x04

String second = "0x" + decodeDecToHex(now.get(Calendar.SECOND)); //Evaluate to 0x08

String timeString = "0x7D, 0x54, 0x06, 
"+ numberthYear+", "+dayYear1+","+dayYear2+",
"+hour+","+minute+", "+second+" 0x01, 0x10";

格式与uploadCommand2的格式相同。

但是那么如何将字符串timeString写入outputstream通过套接字，因为writeByte只接受int？
