为什么要获得助听设备的 GATT 规范如此困难？

如何解决为什么要获得助听设备的 GATT 规范如此困难？

我正在尝试查找血糖仪和助听器的蓝牙 GATT 规范。 但我唯一发现的是

https://www.bluetooth.com/specifications/gatt/removed/

或 git hub 上的一些较旧的存储库。

蓝牙对任何人都不是免费的吗？

我想为听力设备开发一个简单的音量控制，例如我可以在这里扫描并找出：

但是没有可用的字典来获取有关特征结构的更深入信息。 助听器是 Amplifon ampli-connect B 5 VS。

感谢任何帮助或建议。

解决方法

不幸的是，在过去几年中，bluetooth.com 变得更加难以搜索。他们已经淘汰了很多观众，你必须阅读 PDF。但数据还在。

有关支持 LE Audio 的助听器，请参阅 Volume Control Profile and Service。有关实际特征值，请参阅 16-bit UUID Numbers Document。例如，音量控制服务是 0x1844，音量状态特征是 0x2B7D。有关详细信息，请参阅文档（并不复杂，但也不明显）。

但是，许多助听器不使用 LE 音频。我相信第一个是在 2014 年左右发布的。许多使用 HFP 和/或 A2DP，Core Bluetooth 无法访问它们。在这种情况下，不支持更改音量的方法。 （您可以使用隐藏的 MPVolumeView 玩游戏并以编程方式找到滑块并移动它，我已经为某些产品这样做了，但我真的不推荐它。它非常脆弱且不受支持。）HFP 通常用于电话，专为语音而设计。 A2DP 提供更高质量的音频，通常用于音乐。在大多数情况下（取决于 AVAudioSession 的配置方式），支持任一设备的设备将自动显示在 iPhone 的控制面板中。

您在此处展示的设备有一堆 128 位 UUID，强烈建议使用自定义协议，可能旨在供听力学家使用制造商提供的软件使用。专有 BLE 协议在耳塞领域（我工作的地方）非常普遍，根据我对助听器的了解，我预计它们在那里也很常见。

Bluetooth.com 不再在其网站中提供 XML 查看器。您需要将配置文件下载为 PDF 文件。

例如：

对于 CGMP - https://www.bluetooth.org/docman/handlers/downloaddoc.ashx?doc_id=310501 对于 CGMS - https://www.bluetooth.org/docman/handlers/downloaddoc.ashx?doc_id=310502

基本上，只需转到 https://www.bluetooth.com/specifications/gatt/ 并点击 1.0.1 编号。

这是您要找的吗？规格/简介？
