Dear all
I am new to this place. Thanks for any help first.
I have tried to fork two process, One use socket system call -
accept at rfcomm channel 2, and another try to connect to a bluetooth
device thought channel 3. But i found that i can not use a 3rd device to
connect to the listen channel 2 at the same time.
I am using bluez-lib-2.6, utils-2.6. ,hci-uart and linux-2.4.18
patched with patch-2.4.18-mh15.
My question is simple, Could bluez be multi-tasking?
best regard
Mike,Lee

show us the source code for that.

The bluez-libs and bluez-utils are at version 2.11 and you should update
both of them.

You may not be able to do some crazy things, but in general yes.

Dear Marcel
Thanks for helping.
Here is code fragment. I use usual fork practise to run these two
func do_connect and do_listen. I hard code the bluetooth device to be
connected just because code is under testing.
And these two func are using different channel, it can be connected
when do_connect retry more than 3 times.
So i do not why it can not be connected when it is trying to connect
another device.
int *do_connect*(TPVSerial_State_t *stateData)
{
struct sockaddr_rc sa;
int sk,retry;
// Create RFCOMM socket
sk = socket(AF_BLUETOOTH, SOCK_STREAM, BTPROTO_RFCOMM);
sa.rc_family = AF_BLUETOOTH;
sa.rc_channel = 3;
str2ba("00:e0:07:cb:15:68",&sa.rc_bdaddr);
retry = 3;
while(retry--)
{
int ret, alen = sizeof(sa);
DEBPRINT("Conecting...\n");
ret = connect(sk, (struct sockaddr *) &sa, alen);
DEBPRINT("Connected\n");
ba2str(&sa.rc_bdaddr, ba);
syslog(LOG_INFO, "New connection from %s", ba);
// to handle the SPP connection
sp_open_connection(sk, stateData);
close(sk);
}
return 0;
}
int *do_listen*(TPVSerial_State_t *stateData)
{
struct sockaddr_rc sa;
int sk;
fd_set netfd;
// Create RFCOMM socket
sk = socket(AF_BLUETOOTH, SOCK_STREAM, BTPROTO_RFCOMM);
sa.rc_family = AF_BLUETOOTH;
sa.rc_channel = 2
sa.rc_bdaddr = src_addr;
if (bind(sk, (struct sockaddr *) &sa, sizeof(sa)))
{
syslog(LOG_ERR, "Bind failed. %s(%d)", strerror(errno), errno);
return -1;
}
listen(sk, 10);
FD_ZERO(&netfd);
terminate = 0;
while(!terminate)
{
int alen = sizeof(sa), nsk;
FD_SET(sk,&netfd);
syslog(LOG_INFO, "Waiting for connection...");
DEBPRINT("wait Accept\n");
select(sk+1,&netfd,NULL,NULL,NULL)
if(FD_ISSET(sk,&netfd)){
nsk = accept(sk, (struct sockaddr *) &sa, &alen);
DEBPRINT("Accepted\n");
ba2str(&sa.rc_bdaddr, ba);
syslog(LOG_INFO, "New connection from %s", ba);
// to handle the SPP connection
sp_open_connection(nsk, stateData);
close(nsk);
}
}
return 0;
}

Hi Mike,
you posted your request to both mailing lists. Don't do any cross
posting.

I don't get your point. Make it clear who is connecting to whom.
And if you don't set your socket to non-blocking the use of select makes
no sense. Show us the full code.

Marcel

Dear Marcel
Thanks for helping. and sorry for disturbing two mailing list.
Here are the codes generate problems.(i omitted some codes because
of the size)
My english is no good, I try to make it clear.
There are 3 device, Target device, computer A, computer B. Target device
is running the code below i.e. connect to computer A through channel 3
and listen at channel 2. It supposed that computer B can connect to
target device when target device is connecting others, but it fails. And
when target stop connecting computer A, computer B can then connect to
target with channel 2!
int main(void)
{
if ((connect_pid=fork())==0)
{
DEBPRINT("Connect process %d\n",getpid());
printf("Start connecting...\n");
do_connect(&stateData);
return 0;
}
else
{
DEBPRINT("RTSP listen process %d\n",getpid());
// waiting phone to connect
printf("Start listening...\n");
do_listen(&stateData);
}

what are the outputs of "hciconfig -a" for these three devices?

this one is fine, because it is a HCI 18.x firmware.

This one is HCI 14.7 and previous HCI 16.x which is not good.

You can, use "hcitool info ..." as root.

using the latest version is always a good idea, but however the old CSR
firmware before HCI 16.4 can also cause the problems.

the 2.4.18-mh15 contains the newest Bluetooth subsystem you will get for
a 2.4 kernel. Why don't you use a 2.6 kernel?

fine with me, but I think the 2.4 kernel misses at least 30 patches that
are merged with the 2.6 series.

Hi Mike,
> You mean that i can patch the 2.4 to 2.6? from kernel.org?
no. You already use the newest Bluetooth subsystem available for 2.4 and
if you wanna use the Bluetooth subsystem of 2.6, you have to backport
over 30 patches. It is a doable job, but not an easy one.

Marcel

Hi Mike,

no, because RFCOMM is a stream. All MTU stuff is hidden inside the
implementation.

# ls bluez-libs-2.12/src
bluetooth.c hci.c Makefile.am Makefile.in sdp.c
So I guess libbluetooth contains sdp.

the SDP library is part of the Bluetooth library now. I did this change
some time ago. May you should start reading the changelogs.
