我一直在尝试使用this BTStack implemented by Bluekitchen通过经典的蓝牙将ESP-32微控制器连接到XBox One S无线控制器。我设法连接了两个设备（以ESP-32作为主机），并且可以从ESP-32上的控制器读取所有值。我现在正在尝试找出如何将有效报告发送到控制器。控制器在连接时报告的描述符是这样的：

当我通过this translator运行此转储时，由于该问题很长，因此我在问题末尾得到了可读的输出。这里只列出了HID描述符的输出报告格式：

我对HID标准的理解将表明描述符的这一部分是无效的，因为Usage (0x70)后跟Report Count (4)，这是我用来调试为什么它不起作用的btstack解析器然后必须尝试将4个字节匹配为单个用法，据我所知无法做到这一点。当前，我要发送给控制器（和调试时解析器）的报告是0x03, 0xF0, 0x64, 0x64, 0x64, 0x64, 0xFF, 0x10, 0x05，其中0x03表示报告ID，以下值表示我要发送的参数控制隆隆声马达。 4个0x64值是应该映射为4种用法的4个字节，但是根据HID描述符，仅对应于1种用法0x70。目前，解析器在找到第一个0x64之后停止并声称已完成。
我认为这个HID描述符无效是我错了吗？如果是，是否有人知道我应该发送什么报告来匹配此HID描述符模板。很抱歉这个问题的冗长。
预先感谢， 理查德

答案 0 :(得分：0)
事实证明，由于电池“电量不足”，控制器已禁用了振动电机，并且将问题中描述的报告（开始时带有0xA2）发送给了我更换电池后的预期效果。我仍然不确定HID描述符实际上在语法上是否有效，但是控制器至少要执行我现在想要的操作！

我知道您已经找到了问题，但是其他人可能对此很感兴趣。我用hidrdd解码了HID描述符（指出错误并提出改进建议）。结果如下：

报告描述符似乎一般都可以。我可以将其从306个字节优化到仅191个字节-表示完全相同的数据流（见下文）。
至于0x70的使用情况，在我看来，可以使用4位DcEnableActuators用法（0x97）启用4个执行器。所以我想您应该发送：
0x03, 0x0F, 0x64, 0x64, 0x64, 0x64, 0xFF, 0x10, 0x05
以启用全部四个，而不是：
0x03, 0xF0, 0x64, 0x64, 0x64, 0x64, 0xFF, 0x10, 0x05
只是为了好玩，这是他们可以改用的报告描述符的优化版本：
