atk_8266_wifiap_test函数
作用:ATK-ESP8266 WIFI AP 测试函数

/***********************************************************/
//ATK-ESP8266 WIFI AP 测试
//用于测试TCP/UDP 连接
//返回值:0,正常
//其他,错误代码
u8 atk_8266_wifiap_test(void)
{
  u8 netpro=0;        //网络模式
  u8 key;
  u8 timex=0;   
  u8 ipbuf[16];         //IP 缓存
  u8 *p;
  u16 t=999;        //加速第一次获取链接状态
  u8 res=0;
  u16 rlen=0;
  u8 constate=0;                       //连接状态
  p=mymalloc(SRAMIN,32);              //申请 32字节内存
  ……………                            //省略部分代码
  return res;
}
/***********************************************************/

以上代码,我们省略了大部分与串口 STA 模式类似的代码,仅列出了关键区别代码其中 AT+CWSAP 指令的参数:wifiap_ssid,wifiap_encryption,wifiap_password 等是在common.c里面定义的字符串,如下:

/***********************************************************/
//WIFI AP 模式,模块对外的无线参数,可自行修改.
const u8* wifiap_ssid="ATK-ESP8266";      //对外 SSID 号
const u8* wifiap_encryption="wpawpa2_aes";    //wpa/wpa2 aes加密方式
const u8* wifiap_password="12345678";        //连接密码
/***********************************************************/

以上配置,设置模块的对外无线参数,其中 SSID 为:ATK-ESP8266;加密方式为:WPA/WPA2_AES;密码为:12345678
整个代码实现了对模块串口无线 AP(COM-WIFI AP)模式各个子模式的测试(TCP 服务器、TCP 客户端、UDP)。这里,该函数根据不同的子模式,按照1.1.2节的3 个表格里面的指令来对模块进行配置,从而实现子模式配置。对于客户端模式,还会要求输入远端IP 地址,此时,可以通过触摸屏输入远端IP
剩下的处理,同串口 STA(COM-STA)模式的处理方式
