Under a machine sent 11 bytes starting with fixed data such as 0 xfe 0 xfe 0 XCC 0 xc2 as the beginning of the application in judgment only 0 xfe 0 xfe
Middle including fixed 0 x00 to 0 x00 0 x00 0 x01 0 x00 xd5 0 0 xc2
Bluetooth example of using Google byte& & 0 XFF to unsigned
But only at the beginning to judge the first complete data string won't get back again
