下面是socket的建立源码
signed char appSocketConnect(void) { smtpSocket = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP); if (smtpSocket == -1) { wlan_stop(); return -1; } tSocketAddr.sa_family = AF_INET; tSocketAddr.sa_data[0] = (port & 0xFF00) >> 8; tSocketAddr.sa_data[1] = (port & 0x00FF); //correcting the endianess tSocketAddr.sa_data[2] = smtpServerIP[0]; // First octet of destination IP tSocketAddr.sa_data[3] = smtpServerIP[1]; // Second Octet of destination IP tSocketAddr.sa_data[4] = smtpServerIP[2]; // Third Octet of destination IP tSocketAddr.sa_data[5] = smtpServerIP[3]; // Fourth Octet of destination IP smtpServerFlag = connect(smtpSocket, &tSocketAddr, sizeof(tSocketAddr)); if (smtpServerFlag < 0) { // Unable to connect return -1; } else { smtpServerFlag = 1; //success } // Success return 0; }
下面是发送源码
send(smtpSocket,"Hello",6,0);
网络调试助手能收到消息。但是CC3000在发送完之后就会进入死循环,调试原因发现是进入了
if (wlan_tx_buffer[CC3000_TX_BUFFER_SIZE - 1] != CC3000_BUFFER_MAGIC_NUMBER)
wlan_tx_buffer这个buf的第58个字节被覆盖为0x01了
然后官方给的处理是死循环。但是我吧while注释完之后,也能正常的连续发送。
请问下这是什么原因导致的。
非常感谢!!!
