byte[] cbuf = new byte[4];
socketReader.read(cbuf, 0, 4);
int Param_Code = byteArrayToIntBI(cbuf, 0);

public static int byteArrayToIntBI(byte[] b, int offset) {
        int value = 0;
        for (int i = 3; i > -1; i--) {
            int shift = (i) * 8;
            value += (b[i + offset] & 0x000000FF) << shift;
        }
    return value;
   }

• 备选办法1:有时Param_code仅适用于ID

• 备选办法2:有时Param_code对0x40000+ID

• 备选办法3:有时Param_code对0x80000+ID

我的问题是,如何从考虑上述选择的Param_代码中获取ID。

如何使用拜特布耳机?

byte[] cbuf = new byte[4];
socketReader.read(cbuf, 0, 4);
ByteBuffer buffer = ByteBuffer.wrap(cbuf);
int Param_Code = buffer.getInt();
