android - 需要在 Android ICS 上使用摩托罗拉 GATT 配置文件 API 的蓝牙低功耗示例

Question

从今天起，摩托罗拉开发者门户网站将问题重定向到 Stack Overflow 和 Google 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(在我的例子中是 Atrix HD)上开发一个简单的应用程序，它可以查询和写入 GATT 配置文件(不仅仅是心率监测器)。

说明/示例位于 http://www.motorola.com/sites/motodev/library/bluetooth_gatt_apis.html对于 ICS，充其量是不完整的。例如，ICS 下载中不包含 MOT_BTLE_Stubs.jar。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 附加组件包含一个示例，它引导我生成 ACTION_GATT Intent ，但当我为以下内容返回 NULL 时失败了:

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较小但不断发展的 Android BLE 开发者社区提供很好的服务。

谢谢!

我偶然发现了完全相同的问题。

我的 Razr XT910 已更新到 Android ICS (4.0.4)，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 Addon 示例“Motorola_BLE_profile_sample”，我将其用作配置文件模板以与运行 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(...) 包含有效的 GATT Primary Service Declaration UUID您要连接到的设备实现。这将解决空 ObjectPathArray 的问题。

例如，我的 key 扣使用 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.pdf) at page 14 in figure 20. 你看到句柄 0x01, 0x0C, 0x0F 的类型 0x2800 了吗，这些都是主要服务。您可以找到 GATT 配置文件属性类型 here .现在您将配置文件模板 (Motorola_BLE_profile_sample) 从

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

到:

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

运行应用程序后，LogCat 如下所示:
