Hello everybody
this is my "server-code":
int client = accept(sock, (struct sockaddr *)&addr, &alen))
char out[] = "200 100";
send(client, out, strlen(out), 0);
// sleep(2);
close(client);
I wrote a little client with the avetana library on my laptop and i'm able
to receive the message "200 100".
I tested it with my mobile phone (with exactly the same code as with the
avetana library). Here I'm unable to receive the data. as soon as i try to
open the inputstream, an exception ("connection already closed") is thrown.
If I uncommend the sleep, it works an i get "200 100".
I now don't know where the source of the problem could be. Do I miss
something important? Mobile Phone bug?
btw, I tested it with the bluetooth-terminal from kde and only receive "200
10". -> where is the last "0"?
kind regards
Marco Trudel

I have no idea with the Java problem, but if you send only strlen()
bytes then you miss the null byte at the the end. So even for a char
array you should use sizeof(). If this is a text based protocol you
start to run over RFCOMM send add "\r\n" may also be a good idea.
