CC3220SF Launchxl :MQTT_client_server例程代理连接失败

开发板：CC3220SF Lanuchxl                                              例程：MQTT_client_server

SDK：simplelink_cc32xx_sdk_4_20_00_07

hi！你们好，我在使用 CC3220SF 导入例程 rtos/CC3220SF_LAUNCHXL/demos/MQTT_client_server 后，设置好 AP 连接的参数（本地wifi账号密码） ， 烧写进开发板后终端上总显示代理连接失败，连本地的客户端好像也连接失败了，我该如何作出调整才能连接成功呢？

终端显示：

如果有人能帮助我，我将感激不尽！

Viki Shi：

1.除了修改账号密码，其他是否有更改?
2.开发板是官方板还是自制板？

1.除了修改以下部分，其余代码并为修改

/* AP SSID*/
#define SSID_NAME"hopetruly"
/* Security type (OPEN or WEP or WPA)*/
#define SECURITY_TYPESL_WLAN_SEC_TYPE_WPA_WPA2
/* Password of the secured AP*/
#define SECURITY_KEY"12345678"
