在原子哥的例程上稍微改动了一下，建立STA TCP client 模式下与电脑的通信。接收数据没有问题，但是发送数据只有第一次成功，之后总是连接不上。不知道什么问题，还请大家赐教。
发送数据部分代码如下：- //WIFI STA ·¢ËÍÊý¾Ý
- //length :·¢ËÍÊý¾Ý³¤¶È
- //pointer:Ö¸Ïò·¢ËÍÊý¾Ý £¡£¡£¡£¡£¡£¡£¡£¡Ö¸ÕëÀàÐ͸ù¾ÝÊý¾Ý²»Í¬¿ÉÄÜÒª¸Ä£¡£¡£¡
- void atk_8266_wifista_send(u8 length,char *pointer)
- {
- u8 *q;
- u8 j;
- q=mymalloc(32); //ÉêÇë32×Ö½ÚÄÚ´æ
- atk_8266_quit_trans();
- while(atk_8266_send_cmd("AT+CIPSEND","OK",20)); //¿ªÊ¼Í¸´«
- {
- if(!atk_8266_send_cmd("AT+CIPSEND","ERROR",20))//Èô¶Ï¿ª£¬ÔòÖØÐÂÁ¬½Ó
- {
- sprintf((char*)q,"AT+CIPSTART="TCP","%s",%s","192.168.43.186","8080"); //ÅäÖÃÄ¿±êTCP·þÎñÆ÷
- while(atk_8266_send_cmd(q,"OK",200));
-
- atk_8266_send_cmd("AT+CIPMODE=1","OK",200); //´«ÊäģʽΪ£ºÍ¸´«
- USART2_RX_STA=0;
- atk_8266_quit_trans();
- }
- }
- for(j=0;j<length;j++) //Ñ»··¢ËÍÊý¾Ý
- {
- while(USART_GetFlagStatus(USART2,USART_FLAG_TC)==RESET); //Ñ»··¢ËÍ,Ö±µ½·¢ËÍÍê±Ï
- USART_SendData(USART2,*(pointer++));
- }
-
- myfree(q); //ÊÍ·ÅÄÚ´æ
-
- }
仿真死在这一步：- while(atk_8266_send_cmd("AT+CIPSEND","OK",20)); //¿ªÊ¼Í¸´«
- {
- if(!atk_8266_send_cmd("AT+CIPSEND","ERROR",20))//Èô¶Ï¿ª£¬ÔòÖØÐÂÁ¬½Ó
- {
- sprintf((char*)q,"AT+CIPSTART="TCP","%s",%s","192.168.43.186","8080"); //ÅäÖÃÄ¿±êTCP·þÎñÆ÷
- while(atk_8266_send_cmd(q,"OK",200));
-
- atk_8266_send_cmd("AT+CIPMODE=1","OK",200); //´«ÊäģʽΪ£ºÍ¸´«
- USART2_RX_STA=0;
- atk_8266_quit_trans();
- }
- }
电脑接收结果如下：- 【Receive from 192.168.43.254 : 25700】：
- AT+CIPSEND
- L0E+++
- AT
- AT+CIPSEND
- AT+CIPSEND
- AT+CIPSEND
- AT+CIPSEND
- AT+CIPSEND
- AT+CIPSEND
- AT+CIPSEND
- AT+CIPSEND
