1.已经确认没有 调用sl_WlanProfileDel 这个接口。

只是偶尔会丢失 读不到profile文件。 请问有可能是什么情况会导致profile丢失

2.想问下 如果sl_WlanProfileAdd  方式写入了  那么 可以通过css uniflash工具 去查看 文件是否存在吗？（这个profile是默认存在系统中的还是 执行sl_WlanProfileAdd  的时候 生成的新文件）

    WLAN profiles are designed to allow connections to pre-defined stored access-points. A profile provides the information required to connect to a given AP. This information includes the SSID, security-type and security-keys of an AP. Each profile refers to a certain AP. The profiles are stored on the non-volatile memory, and therefore are preserved during device reset.

    ，profile是存在NV memory中的，可以通过"sl_WlanProfileGet"读取，重启不回导致文件丢失

    "sl_WlanProfileGet" - Used for retrieving information of certain stored profile. Index shall be the input parameter
