STM32 ESP8266 STA client 与电脑通讯，发送数据失败

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 ·￠Ëíêy¾Y
//length :·￠Ëíêy¾Y3¤¶è
//pointer:Ö¸Ïò·￠Ëíêy¾Y ￡¡￡¡￡¡￡¡￡¡￡¡￡¡￡¡Ö¸ÕëààDí¸ù¾Yêy¾Y2»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￡¬ÔòÖØDÂá¬½ó
{
sprintf((char*)q,"AT+CIPSTART=\"TCP\",\"%s\",%s","192.168.43.186","8080"); //ÅäÖÃÄ¿±êTCP·tÎñÆ÷
while(atk_8266_send_cmd(q,"OK",200));
atk_8266_send_cmd("AT+CIPMODE=1","OK",200); //′«êäÄ￡ê½Îa￡oí¸′«
USART2_RX_STA=0;
atk_8266_quit_trans();
}
}
for(j=0;j<length;j++) //Ñ-»··￠Ëíêy¾Y
{
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￡¬ÔòÖØDÂá¬½ó
{
sprintf((char*)q,"AT+CIPSTART=\"TCP\",\"%s\",%s","192.168.43.186","8080"); //ÅäÖÃÄ¿±êTCP·tÎñÆ÷
while(atk_8266_send_cmd(q,"OK",200));
atk_8266_send_cmd("AT+CIPMODE=1","OK",200); //′«êäÄ￡ê½Îa￡oí¸′«
USART2_RX_STA=0;
atk_8266_quit_trans();
}
}
