首先，我学习了一些外围设备，如timer,spi。他们工作得很好。然后在DA14580上运行一些BLE示例。他们还工作。但是我不能理解软件架构，即使我阅读一些pdf文件，如umb - 015_da14580软件架构v4.0或umb -003软件开发指南1.4几天。

我的目标是知道如何根据我自己的应用程序写或改编一个proflie。我怎么能这么做?
>顺便说一下，我想问一个具体的软件问题。我在网上找到了一个例子。It can send the same bytes through BLE when it receive some bytes.The function below plays a leading role.It is in streamdatad_task.c,one of the profiles.I don't know how it works.I can't fine any information about some function it calls like attmdb_att_set_value, atts_write_rsp_send,attmdb_att_update_value.This makes me desprate and more confused.
