截至今天，摩托罗拉开发者门户网站正在将问题重定向到 Stack Overflow 和谷歌 Android 论坛，因此希望摩托罗拉的人正在倾听。

我正在尝试在 ICS 设备（在我的情况下为 Atrix HD）上开发一个简单的应用程序，该应用程序可以查询和写入 GATT 配置文件（不仅仅是心率监测器）。

对于 ICS， http://www.motorola.com/sites/motodev/library/bluetooth_gatt_apis.html上的说明/示例充其量是不完整的。例如 MOT_BTLE_Stubs.jar 不包含在 ICS 下载中。相反，我们有 BluetoothGatt.jar 和 BluetoothGattService.jar。但是这些库没有教程中提到的 BluetoothGatt.connectGatt(...)。

ICS 插件包含一个示例，它引导我生成 ACTION_GATT 意图，但是当我收到以下内容的 NULL 返回时失败：

String[] ObjectPathArray = (String[])intent.getStringArrayExtra(BluetoothDevice.EXTRA_GATT);

一个编写良好的 ICS 示例将为摩托罗拉和规模虽小但不断壮大的 Android BLE 开发者社区提供极大的帮助。

谢谢！

我偶然发现了完全相同的问题。

我有一个更新到 Android ICS (4.0.4) 的 Razr XT910，我正在使用摩托罗拉手机 SDK 插件“ Motorola_ICS_R2”。

我现在谈论的是 SDK 插件示例“Motorola_BLE_profile_sample”，我将其用作配置文件模板来与运行 SimplePeripheral 示例的 TI CC2540 开发套件的 Keyfob 进行通信。

当您创建配置文件服务时，请确保调用 BluetoothGattService(...) 包含您要连接的设备实现的有效GATT 主要服务声明 UUID 。这将解决您使用空 ObjectPathArray 的问题。

例如，我的 Keyfob 使用 UUID 0x180A 实现设备信息服务，您可以在 BLE CC2540 开发套件用户指南 (http://www.ti.com/lit/ug/swru270b/swru270b) 中找到 Keyfob 的此信息.pdf) 在图 20 中的第 14 页。您看到句柄 0x01、0x0C、0x0F 的类型 0x2800，这些都是主要服务。您可以在此处找到 GATT 配置文件属性类型。现在您将您的个人资料模板 (Motorola_BLE_profile_sample) 从

    public static final ParcelUuid HRM = ParcelUuid
        .fromString("0000180D-0000-1000-8000-00805f9b34fb");

至：

    public static final ParcelUuid HRM = ParcelUuid
        .fromString("0000180A-0000-1000-8000-00805f9b34fb");

运行应用程序后，LogCat 如下所示：

完全同意您对摩托罗拉文档、示例和开发人员支持的糟糕程度的看法。

我确实找到了这个：http ://www.tekritisoftware.com/how-to-implement-ble-in-android 这可能会有所帮助，但我仍在等待我的 btle 设备，所以还没有尝试过。
