Beginner for DA 14580: Need help to start development

嗨dv，

您可以从SDK中的示例开始。您可以查看邻近示例，然后查看鞍骨筒示例（仅限散布配置文件，只是广告字符串操作），那么您可以查看自定义配置文件示例（ble_app_peripheral和ble app_profile）。此外，您还可以检查新的SDK UM-B-050和UM-B-051的文档。最后，您可以在网站上搜索您的大多数问题。

Thanks MT_dialog

嗨dv，

由于您使用的是SDK 5唯一可用的文档是我上一篇文章中提到的那个，您正在阅读的文档基于SDK 3.也是未能的执行流程和睡眠机制，我会推荐您检查UM-B-006睡眠模式配置。在Proximity Reporter中，您可以在Line〜98中的User_config.h文件中配置广告。创建数据库后，广告从vifult_app_on_db_ini_complete（）一旦创建了数据库，就会开始默认的广告操作。默认的广告操作可以在user_callback_config中配置h。对于main_func检查UM-B-006 to have some insight. About the discovery issued maybe is an application or a device issue, fyi i am able to track the proximity reporter with BLE scanner, have you tried any other application ?

Thanks MT_dialog

嗨dv，

就文件而言，这两个是SDK5的唯一一个，但由于它基于SDK3，基本功能或多或少相同。例如，应该读取描述睡眠功能的UM-B-006 Doc以了解睡眠的概念。关于应用程序，您是否雷竞技安卓下载尝试过另一个电话，设备？

Thanks MT_dialog

嗨dv，

You can see the advertising string with a sniffer but you can't with your phone ? I ve checked with BLE Scanner it discovers and connects to the proximity reporter. What is that you see in your sniffer and doesn't match the advertising data ? Have you tried with any other example the ble_app_peripheral perhaps? You should be able to see in the advertising string the mandatory flags 02 01 06 and then the hex values defined in the USER_ADVERTISE_DATA.

Thanks MT_dialog

嗨dv，

前三个字节是指示广告消息02的类型的强制标志 - 下面的数据的长度 - 遵循的数据的广告标记和标志的06值（LE可发现模式和BR / EDR不支持）。其他未定义的字节是您在代码0C中指定的设备的名称是长度，09是完整的本地名称对话框-PRXR的标签。尽管断开连接，请尝试通过使用嗅探器即可检查断开的原因。如果主机正在终止连接。

嗨dv，

为了改变广告旗,你必须设置the correct configuration in your advertising command. You have to set in the gapm_adv_host struct the mode member in GAP_LIM_DISCOVERABLE. This will set the flag in your advertising data. The limitation of the advertising length is 31 bytes but you have to subtract the 3 mandatory AD flags that indicate the length, if the BR/EDR is supported (which is yes since its not supported) and the advertising mode flag.

Thanks MT_dialog

嗨dv，

广告字符串中的大多数数据由SDK配置在User_Config.h文件中。你想更新什么？如果检查app_easy_gap_undirected_advertise_start_create_msg（）函数，则会看到struct gapm_start_advertise_cmd由user_undircted_advertise_conf struct填充。

1. The USER_ADVERTISE_DATA populates the NVDS structure, in the function i mentioned the code will get the data and populate the advertising string.

2.广告字符串的广告数据空间有限，您必须检查广告数据中是否有足够的可用空间。现在，我想你有足够的空间来放置你的数据，你还必须在广告字符串中设置广告数据的大小，如果你想放置几个Etxra，那么近距离记者的当前长度是“0x09”字节（“0x55，0x55​​”）您必须将长度从“0x09”设置为“0x0b”

3.广告间隔位于.Intv成员中的User_undired_advertise_conf结构中的User_config.h文件中。

嗨dv，

The only documents regarding SDK 5 are the ones that i ve suggested on my seconds post more specific you can go to the 8.2.3.2 paragraph and check all the callbacks for every operation the SDK is using, you can check the definitions of those functions and see how the advertising is performed.

If you want for example to check what kind of advertising the example it performs please check the .default_operation_adv in the user_callback_config.h file that will lead you to the function that instructs the device to advertise. There is a different function for every kind of advertising you want to execute most of the functions are located in app.c file. for example:

- app_easy_gap_undircated_advertise_start（） - 通过调用此功能，您将获得一个无向广告。

- app_easy_gap_dircated_advertise_start（）定向广告

- app_easy_gap_non_connectable_advertise_start（） - 不可连接的广告

您可以更改user_config.h文件中的广告过程的参数。

据更新广告串，鞍骨牌榜样正在做同样的事情请用它作为参考。

Hi

如果可以修改user_device_name，您可以建议吗？

Regards
Nicky

嗨Nicky.Whtsang，

Yes you can change the device's name in the user_config.h file at the USER_DEVICE_NAME definition.
