问 W801的WiFi重连

自动重连建议参考这个demo，通过蓝牙配网成功后也会自动打开自动重连功能。

    u8 auto_reconnect = 0xff;
    tls_wifi_auto_connect_flag(WIFI_AUTO_CNT_FLAG_GET, &auto_reconnect);
    if(auto_reconnect != WIFI_AUTO_CNT_ON)
    {
        auto_reconnect = WIFI_AUTO_CNT_ON;
        tls_wifi_auto_connect_flag(WIFI_AUTO_CNT_FLAG_SET, &auto_reconnect); 
        tls_wifi_connect((u8 *)"w600", strlen("w600"), (u8 *)"12345678", strlen("12345678"));
        printf("--->WIFI_AUTO_CNT_FLAG_SET ON\n");
    }

问 W500是否支持接入中文名AP

W500已经停产了，目前主推是W80X系列，可以支持中文UTF-8编码。
