关于ESP8266的问题，根据原子哥的代码改编了两个函数，但是不好使，求大神指点

void wifiap_init(void)
{
//        u8 netpro=1;        //íøÂçÄ￡ê½
        u8 ipbuf[16] = "192.168.4.2";         //IP»o′æ
        u8 *p;
       
        atk_8266_send_cmd("AT+CWMODE=2","OK",20);
        atk_8266_send_cmd("AT+RST","OK",20);
        sprintf((char*)p,"AT+CWSAP=\"%s\",\"%s\",1,4",wifiap_ssid,wifiap_password);    //ÅäÖÃÄ￡¿éAPÄ￡ê½ÎTÏß2Îêy

现象是程序卡死，接收方接不到数据
