I set the arm as the client and received the data using socket\_read\_ascii\_float();  
My server code is:  
char sendBuf[80] = “(0.46, 0.1, 0.4, 3.14, 0, 0 )”;  
send(sClient, sendBuf, strlen(sendBuf), 0);  
What should I change the code of my server side to make my robot arm receive data ?

You should use printf to add ‘\n’ in the end.
