这段log的意思是在手机上的Wifi服务试图进行扫描时被拒绝，因为它被限流了。在扫描失败后，系统发送了一个广播，通知相关应用有关Wifi扫描结果的变化。接着，设备上的一个客户端（STA）28:c7:09:63:e0:a3从热点（hotspot）断开连接，并在此之后，SoftApManager处理了与连接的客户端数量有关的变化，并安排了一条消息在将来的某个时间进行超时处理。

这段 log 中似乎描述了 WiFi 相关的一些操作。其中，

- "startScan" 和 "Scan request from com.autonavi.amapauto throttled" 描述了有应用请求扫描 WiFi，但是被限制了。
- "STA 28:c7:09:63:e0:a3 IEEE 802.11: disassociated" 和 "Station 28:c7:09:63:e0:a3 disassociated from hotspot" 描述了一个 WiFi 设备 (STA) 从热点 (hotspot) 断开了连接。
- "Number of associated stations changed: 0" 描述了连接到热点的设备数量变为了 0。
- "Timeout message scheduled" 描述了已设置了一个超时消息。

但是，由于这段 log 中缺少上下文信息，我不能提供更多具体的解释。

static_library("iot_wifi") { sources = [ "iot_wifi.c", "iot_netcfg.c", "iot_softap.c", ] cflags = [ "-Wno-unused-variable" ] cflags += [ "-Wno-unused-but-set-variable" ] cflags += [ "-Wno-unused-parameter" ] include_dirs = [ "//kernel/liteos_m/components/net/lwip-2.1/enhancement/include/lwip", "//kernel/liteos_m/components/net/lwip-2.1/porting/include/", "//base/hiviewdfx/hilog_lite/interfaces/native/innerkits/hilog", "//foundation/communication/wifi_lite/interfaces/wifiservice/", "//third_party/mbedtls/include/mbedtls", "//kernel/liteos_m/kal/cmsis", "//third_party/cJSON", "//utils/native/lite/include", "../inc", ] deps = [ "//base/hiviewdfx/hilog_lite/frameworks/featured:hilog_static", ] }

这是一个名为 "iot_wifi" 的静态库的构建配置。它包含了以下源文件：

- iot_wifi.c
- iot_netcfg.c
- iot_softap.c

构建选项中设置了一些编译标志，如忽略未使用的变量和参数。包含的头文件路径如下：

- //kernel/liteos_m/components/net/lwip-2.1/enhancement/include/lwip
- //kernel/liteos_m/components/net/lwip-2.1/porting/include/
- //base/hiviewdfx/hilog_lite/interfaces/native/innerkits/hilog

- //third_party/mbedtls/include/mbedtls
- //kernel/liteos_m/kal/cmsis
- //third_party/cJSON
- //utils/native/lite/include
- ../inc

此外，该静态库依赖于另一个名为 "hilog_static" 的静态库，路径为：

- //base/hiviewdfx/hilog_lite/frameworks/featured:hilog_static
