Hi, yesterday i forgot to attach the screen shot of how i configured this Software platform for my project, now I am resending it with the attachment. Hope that explains or else let me know! In the mean time I have switched over to lwIP RAW API and ported the code. Now what i can see is that the value of err = 0 in the below statement err = tcp_connect(pcb, &ServAddr, 7777, client_connected); and at the same time in the conditional statement if(err == ERR_OK) is satisfied that means I got connected to my server. But the problem arises with writing to the server with this block static err_t client_connected(void *arg, struct tcp_pcb *pcb, err_t err) { char string[] = "Hello!"; LWIP_UNUSED_ARG(arg); if(err != ERR_OK) printf("\n client connected(): err argument not set to ERR_OK, but the value is %d\n", err); else { printf("\n client connected \n"); tcp_sent(pcb, client_sent); tcp_write(pcb, string, sizeof(string), 0); } return err; } where I have asked the client to sending the string "Hello!" to the server. If it is sending to the server how can i find out that it is sending the data. Please feel free to ask any more information you need in this case, since I am a newbie I may not have understood your previous questions correctly.
