Confusion in Properties permission in the DA1469x_Custom_BLE_Service example

Hello Dialog,

我正在测试e examples "BLE_Central" and the "DA1469x_Custom_BLE_Service" to achieve some communication between the GATT client and server. In the custom service example, in the peripheral_task.c, there are two services defined with one and thee characteristics respectively. Here, I have set some random permissions for the characteristics of the both services. Please find the log file attached below.

这些是我所设定的冒充特征权限。

const mcs_characteristic_config_t custom_service_1[] = { /* Initialized Characteristic Attribute */ CHARACTERISTIC_DECLARATION(11111111-0000-0000-0000-000000000001, CHARACTERISTIC_ATTR_VALUE_MAX_BYTES, CHAR_WRITE_PROP_DIS, CHAR_READ_PROP_DIS, CHAR_NOTIF_INDIC_EN, Initialized Characteristic, NULL, NULL, event_sent_cb), }; const mcs_characteristic_config_t custom_service_2[] = { CHARACTERISTIC_DECLARATION(22222222-0000-0000-0000-000000000001, CHARACTERISTIC_ATTR_VALUE_MAX_BYTES, CHAR_WRITE_PROP_EN, CHAR_READ_PROP_DIS, CHAR_NOTIF_NONE, Hello World, NULL, set_var_value_cb, NULL), CHARACTERISTIC_DECLARATION(22222222-0000-0000-0000-000000000002, CHARACTERISTIC_ATTR_VALUE_MAX_BYTES, CHAR_WRITE_PROP_DIS, CHAR_READ_PROP_EN, CHAR_NOTIF_NONE, Hello Dialog, get_var_value_cb, NULL, NULL), CHARACTERISTIC_DECLARATION(22222222-0000-0000-0000-000000000003, 0, CHAR_WRITE_PROP_DIS, CHAR_READ_PROP_DIS, CHAR_NOTIF_NONE, NULL, NULL, NULL, NULL), };

请将附加输出日志的权限进行比较。您可以看到服务1的唯一特征的属性打印为（ - --- i--），即使我已禁用read属性。

Coming to the second service characteristics, They are printed as (-R-W----), (-R------) and (-R------) for the three characteristics respectively which are in contrast with the permissions which I actually gave.

仅根据我给出的内容正确打印第二服务的第二个特征权限。

I request you to investigate about why this happens and suggest me what can I do to avoid this conditions. This is very important for my application as I have to exchange data between the GATT client and the Server.

提前致谢。
