在 基于 Ai-M61-32S 的AP网页配网实现 Step 2 中已经将 WIFI 信息存储到了 flash当中。

接下来就是读取WIFI信息数据，并连接到WIFI。
创建 WIFI相关代码

main.c增加如下内容：
.......
#include "wifi_event.h"
.......
/**
* @brief void queue_task(void* arg)
* 消息队列循环读取
* @param arg
*/
static void queue_task(void* arg)
{
char* ssid = NULL;
char* password = NULL;

password = flash_get_data(PASS_KEY, 32);
if (ssid!=NULL && strlen(ssid) > 0)
{

int main(void)
{
.......
// 初始化 存储

// 启动WiFi任务
wifi_start_firmware_task();
char* ssid = NULL;

if (ssid!=NULL && strlen(ssid) > 0){
xTaskCreate(queue_task, "queue task", 1024*6, NULL, 2, NULL);
}
.......
}
修改 proj.conf 增加如下内容：
# wifi
set(CONFIG_VIF_MAX 2)
set(CONFIG_STA_MAX 4)
set(CONFIG_MAC_TXQ_DEPTH 32)
set(CONFIG_MAC_RXQ_DEPTH 12)
修改 CMakeLists.txt 增加如下内容：
target_sources(app PRIVATE
wifi/wifi_event.c // 增加wifi相关代码
storage/storage.c
web/cJSON.c
web/mlwip_https.c
)
目前当前方案存在以下问题：
- 中文WIFI名称无法连接
- 设置WIFI信息后AP消失
- WIFI信息填写错误，无法修复并且重新编译也不行
解决方案：
- 尽量使用和连接英文WIFI
- 重新烧写固件
- 擦除芯片内容烧写
flash_prog_cfg.ini 配置文件
将
[cfg] # 0：无擦除，1：程序化截面擦除，2：芯片擦除
0: no erase, 1:programmed section erase, 2: chip erase
erase = 1
改为
[cfg] # 0：无擦除，1：程序化截面擦除，2：芯片擦除
0: no erase, 1:programmed section erase, 2: chip erase
erase = 2
再执行 make flash COMX=COM？【？代表你的COM号】 命令就可以擦除数据了。
到这里基于 Ai-M61-32S 的AP网页配网实现就完成了。
如果觉得还不错的话，可以 给个 
+ 1 哦。
