DA1469x_Custom_BLE_Service示例中的属性权限混淆

你好,对话框,

我正在测试示例“BLE_Central”和“DA1469x_Custom_BLE_Service”，以实现GATT客户端和服务器之间的一些通信。在自定义服务示例中，在peripheral_task.c中，有两个服务分别定义了一个和三个特征。在这里，我为这两个服务的特性设置了一些随机权限。请找到下面附的日志文件。

这些是我设置的特性权限。

请比较所附的输出日志的权限。您可以看到服务1的惟一特性的属性被打印为(-R——I——)，尽管我已经禁用了Read属性。

接下来是第二个服务特征，它们分别打印为(-R- w ----)、(-R------)和(-R------)，这三个特征与我实际给出的权限形成了对比。

根据我给出的内容，只有第二个服务的第二个特征权限被正确打印。

我要求您调查为什么会发生这种情况，并建议我可以做些什么来避免这种情况。这对我的应用非常重要，因为我必须在GATT客户端和服务器之间交换数据。

提前谢谢。

问候，
