回覆： Re: [lwip-users] HELP! About the RAW API

[陳 小擁]

Hi Prateek :

    I have got the pcb yet ! i find that i just can sent the data for several times . After i skipped the LwIP Code . i find that the pcb->queuelen don't decreased . It means that LwIP didn't get the ACKs from PC . I don't know why . Can you help me or give me some advice ? Thanks !

Prateek Jain <address@hidden> 說：

Use tcp_write API

     iErr = tcp_write(pcb, (void *)iSendBuf, (u16_t)strlen((char *) iSendBuf), 1);

You must be having the pcb (which is used to recv the data)

 

Thanks

Prateek Jain
