你好,我这边有关于TCP协议栈BUG,回包的问题。
SDK版本:1.5.2
服务器IP:121.41.89.229
ESP8266IP:115.214.236.176
见上图,服务器不断发送ACK=82,ESP8266一直不回应82,到最后ESP8266自己RST了。
请问这个是什么原因

请问您在 ESP8266 端是否使能了 keep alive 功能?
没有使能keep alive功能。
是数据包重发导致keep alive的。
我们服务端和ESP8266都没有用keep alvie这个功能的。
Code: Select all
LOCAL void ICACHE_FLASH_ATTR
gw_connect_cb(void *arg)
{
struct espconn *pespconn = arg;
TcpPrint("gw_connect_cb\n");
os_timer_disarm(&check_timer);
espconn_regist_recvcb(pespconn, gw_recv_cb);
espconn_regist_sentcb(pespconn,gw_sent_cb);
espconn_set_opt(pespconn,0x04);
espconn_regist_write_finish(pespconn,gw_write_finish);
init_fddat(fd);
fd->PacketLen = T16(PACK_SIZE(32));
fd->CMDID = T16(CMD_TOKEN);
memcpy(fd->uCmdRsp.tokeninf.Token,Token,MAX_TOKEN);
set_timestamp(&fd->uCmdRsp.tokeninf.tm);
espconn_send(pespconn,(uint8*)fd,PACK_SIZE(32));
os_timer_setfn(&check_timer, (os_timer_func_t *)heart_beat_timer, &gw_conn);
os_timer_arm(&check_timer, 500, 0);
//send_data(PACK_SIZE(32),(char *)fd);
}
