#### 介绍
存放`RSU demo`案例代码

#### 使用说明

##### 1. 拉取代码到`applications/sample/wifi-iot/app`
```

    ├── sle_uart_server.c
    └── sle_uart_server.h
```

##### 2. 修改`BUILD.gn`
在`applications/sample/wifi-iot/app/BUILD.gn`下添加"rsu:rsu_app"
```
import("//build/lite/config/component/lite_component.gni")

lite_component("app") {
  features = [ 
    "startup",
    "rsu:rsu_app"
  ]
}
```

`applications/sample/wifi-iot/app/rsu/BUILD.gn`选择需要编译的部件打开注释。
```
import("//build/lite/config/component/lite_component.gni")

group("rsu_app") {
  deps = [
    "easy_wifi_demo:easy_wifi_demo",
    "sle_uart_server:sle_uart_server",
    # "sle_uart_client:sle_uart_client",
  ]
}
```
##### 3. 在device/soc/hisilicon/ws63v100/sdkv100/build/config/target_config/ws63/config.py文件的`'ram_component': []`中添加相应的静态库部件，在device/soc/hisilicon/ws63v100/sdkv100/libs_url/ws63cmake/ohos.cmake文件的`set(COMPONENT_LIST)`也进行添加；

config.py
```
        'ram_component': [
            .......
            "sle_uart_server",
            "wifi_demo",
            "easy_wifi",
        ],
```

ohos.cmake
```
elseif(${TARGET_COMMAND} MATCHES "ws63-liteos-app")
set(COMPONENT_LIST "begetutil"   "hilog_lite_static" "samgr_adapter" "bootstrap" "fsmanager_static" "hal_update_static" "hilog_static" "inithook"   "samgr_source"
        "broadcast" "hal_file_static"   "init_log"  "native_file" "udidcomm"
        "cjson_static" "hal_sys_param" "hichainsdk" "hota" "init_utils"  "param_client_lite"
        "hiview_lite_static" "hal_sysparam" "hievent_lite_static" "huks_3.0_sdk"   "samgr" "blackbox_lite" "hal_iothardware" "wifiservice"
        "hidumper_mini" "sle_uart_server" "wifi_demo" "easy_wifi")
```

##### 4. 修改wifi账户密码（需要连接wifi时）
修改`applications/sample/wifi-iot/app/rsu/easy_wifi_demo/demo/wifi_connect_demo.c`的ssid和preSharedKey。
```
static void WifiConnectTask(int *arg)
{
    (void)arg;

    osDelay(TEN);

    // setup your AP params
    // 设置AP参数，包括SSID、预共享密钥、安全类型（PSK）、netID
    WifiDeviceConfig apConfig = {0};
    if (strcpy_s(apConfig.ssid, sizeof(apConfig.ssid), "MERCURY_lijing24876@")) {
        printf("OK");
    }

    if (strcpy_s(apConfig.preSharedKey, sizeof(apConfig.preSharedKey), "lijing24876@")) {
        printf("OK");
    }

    apConfig.securityType = WIFI_SEC_TYPE_PSK;
    ...
}
```

##### 5. 编译烧录

###### nearlink_dk_3863

1. 设置编译产品

```
hb set -p nearlink_dk_3863
```
	
2. 编译

```
hb build -f
```
3. 制品存放在以下路径
```
out/nearlink_dk_3863/nearlink_dk_3863/ws63-liteos-app/
```

###### nearlink_dk_3863_xts

1. 设置编译产品

```
hb set -p nearlink_dk_3863
```
	
2. 编译

```
hb build -f  -b debug --gn-args build_xts=true
```
3. 制品存放在以下路径
```
out/nearlink_dk_3863/nearlink_dk_3863_xts/ws63-liteos-xts/
```

##### 6. Q&A
1. MQTT编译不过的问题:
在 near_link_sdk/device/soc/hisilicon/ws63v100/sdkv100/open_source/mqtt/CMakeLists.txt 中的 set(PRIVATE_DEFINES 添加 宏HIGH_PERFORMANCE
```txt
set(PRIVATE_DEFINES
    ZERO_SOCK_FD_IS_INVALID
    HIGH_PERFORMANCE
)
```
