我一直在尝试使用Bluekitchen 实现的 BTStack通过经典蓝牙将我的 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。我现在正在尝试研究如何向控制器发送有效报告。控制器在连接时报告的描述符是这样的：

05 01 09 05 A1 01 85 01 09 01 A1 00 09 30 09 31 15 00 27 FF FF 00 00 95 02 75 10 81 02 C0 09 01 A1 00 09 33 09 34 15 00 27 FF FF 00 00 95 02 75 10 81 02 C0 05 01 09 32 15 00 26 FF 03 95 01 75 0A 81 02 15 00 25 00 75 06 95 01 81 03 05 01 09 35 15 00 26 FF 03 95 01 75 0A 81 02 15 00 25 00 75 06 95 01 81 03 05 01 09 39 15 01 25 08 35 00 46 3B 01 66 14 00 75 04 95 01 81 42 75 04 95 01 15 00 25 00 35 00 45 00 65 00 81 03 05 09 19 01 29 0A 15 00 25 01 75 01 95 0A 81 02 15 00 25 00 75 06 95 01 81 03 05 01 09 80 85 02 A1 00 09 85 15 00 25 01 95 01 75 01 81 02 15 00 25 00 75 07 95 01 81 03 C0 05 0F 09 21 85 03 A1 02 09 97 15 00 25 01 75 04 95 01 91 02 15 00 25 00 75 04 95 01 91 03 09 70 15 00 25 64 75 08 95 04 91 02 09 50 66 01 10 55 0E 15 00 26 FF 00 75 08 95 01 91 02 09 A7 15 00 26 FF 00 75 08 95 01 91 02 65 00 55 00 09 7C 15 00 26 FF 00 75 08 95 01 91 02 C0 85 04 05 06 09 20 15 00 26 FF 00 75 08 95 01 81 02 C0

当我通过这个翻译器运行这个转储时，我得到了一个可读的输出，它包含在问题的末尾，因为它很长。此处仅列出 HID 描述符的输出报告格式：

我对 HID 标准的理解表明描述符的这一部分是无效的，因为Usage (0x70)后面跟着Report Count (4)，我用来调试为什么这不起作用的 btstack 解析器然后必须尝试将 4 个字节与单个用法匹配并且据我所知，无法做到这一点。目前，我尝试发送给控制器（以及在我调试时发送给解析器）的报告是0x03, 0xF0, 0x64, 0x64, 0x64, 0x64, 0xFF, 0x10, 0x05，其中0x03表示报告 ID，以下值表示我发送以控制振动电机的参数。这 4 个0x64值是应该映射到 4 个用法的 4 个字节，但是0x70根据 HID 描述符仅对应于 1 个用法。目前，解析器在找到第一个0x64并声称已完成后停止。

我认为这个 HID 描述符无效是错误的吗？如果我是，有谁知道我应该发送什么报告来匹配这个 HID 描述符模板。对不起这个问题的混乱/长度。

在此先感谢，理查德

我知道你已经发现了这个问题，但这可能会引起其他人的兴趣。我用hidrdd解码了 HID 描述符（它指出了错误并提出了改进建议）。结果如下：

报告描述符似乎一般都可以。我可以将它从 306 字节优化到仅 191 字节——代表完全相同的数据流（见下文）。

至于 0x70 的使用，在我看来有 4 个执行器可以使用 4 位 DcEnableActuators 使用 (0x97) 来启用。所以我猜你应该发送：

0x03, 0x0F, 0x64, 0x64, 0x64, 0x64, 0xFF, 0x10, 0x05

为了启用所有 4 个而不是：

0x03, 0xF0, 0x64, 0x64, 0x64, 0x64, 0xFF, 0x10, 0x05

只是为了好玩，这里是他们可以使用的报告描述符的优化版本：

事实证明，由于电池“电量不足”，控制器已禁用振动电机，并且发送问题中描述的报告（开头为 0xA2）按我更换电池时的预期工作。我仍然不确定 HID 描述符在语法上是否真的有效，但控制器至少现在做了我想要的！
