Hi Marco!
I've put some functions you posted before into my main program. As I wish to write the program to act as server, I wrote like this:
int main (int argc, char **argv)
{
//variable declaration...
addr.rc_family = AF_BLUETOOTH;
bacpy(&addr.rc_bdaddr, BDADDR_ANY);
addr.rc_channel = 4;
alen = sizeof(addr);
//mysql initialization....
while (1)
{
// request a socket from the operating system
if((sock = socket(AF_BLUETOOTH, SOCK_STREAM, BTPROTO_RFCOMM)) < 0)
{
printf("socket(...) failed");
exit(1);
}
// bind the socket to the system
if(bind(sock, (struct sockaddr *)&addr, alen) < 0)
{
printf("bind(...) failed\n");
exit(2);
}
// set the socket into listen mode. handle 10 (QUEUE) connections.
if(listen(sock, 10) < 0)
{
printf("listen(...) failed\n");
exit(3);
}
while(client = accept(sock, (struct sockaddr *)&addr, &alen))
{
char remoteAddr[18];
ba2str(&addr.rc_bdaddr,
remoteAddr);
printf("connection from %s:\n", remoteAddr);
// send a "hello from server" to client
char out[] = "hello from server";
send(client, out, strlen(out), 0);
printf("> %s\n", out);
// read the answer
char buffer[101]; // buffer size 100, 1 for '\0'
int noReadChars = recv(client, buffer, sizeof(buffer)-1, 0);
buffer[noReadChars] = '\0'; // here the received answer ends
printf("< %s\n", buffer);
while (1)
{
.......
After I ran it, the sock, bind and listen functions were all passed. But after that, I couldn't see any result about it. Then I wish to fiind out how to connect SE T610 to bluez in my PC, but I couldn't find the method. And the strange thing is that the phone could search my PC and then added it on the "My device" list, I was wondering why couldn't the phone initialize the connection to PC. I'm very surprising that Jay Summet said that T610 cannot connect to bluez in Linux PC. So I wish Jay also to explain why, and does it mean that there is no method that T610 can really initialize the connection to PC?
By the way, after I looked at the specification of the bluetooth system, I could not find any way to write sdp program. So, can you and other mail users suggest a method for me to do? I really thank you very much for your kindness.

this has nothing to do with it. i think you tutor is wrong...
if your pc is listening on a rfcomm channel, then you can connect with a
url like btspp://0123456789AB:4
the first part is the protocol, the second the mac address, the last one
the channel number.
have you tried/understood my last post to you:
http://sourceforge.net/mailarchive/message.php?msg_id=10756581
you need a sdp-entry only if the mobile phone wants to do a service search
(paging) what's not needed. a inquiry could get you the mac address and you
then can connect to the listening port in your program.
if it still doesn'
t work,
please send a description of what you exactly do
and what the exact results are. please use hcidump as well...
regards
Marco
