Subject: [Bluez-users] rfcomm question 2-AT command

Hi Marcel!
I have written a program that the menu can be sent to T610 by AT command. However, I face a problem. When I send one menu to the mobile, there is 4-5 seconds delay. The syntax of my program is:
sprintf(command, "AT*EASM=\"Bt-IrConverter\",1,1,%d", item_brand+1);
ret_code=put_command (command, answer, sizeof (answer), 5, 0);
for (j=0; j<item_brand; j++)
{
sprintf(command, ",\"%s\"", device[j]);
ret_code=put_command (command, answer, sizeof (answer), 5, 0);
}
sprintf(command, ",\"quit\",\r");
where the variable device[j] stores the string extracted from MySQL db. So, why is that? And how can I reduce the delay?
Thank you very much.
Michael

run it with "hcidump -t -X" and make sure that your email client don't
insert any line breaks in the dump. And you need to also get the initial
creation of the connection. Otherwise the PSM tracking won't work and
the RFCOMM decoder is not working.

Regards

Marcel

Hi Marcel!
When I ran my main program with "hcidump -t"
running in other terminal, the following occurs:
When I choose an item and then the other menu, for
which the items are found in MySQL DB, is generated,
the hcidump -t shows

Then does it mean that the items are too much that
the sending of AT command from PC to T610 has delay?
And what is the cause of the delay?
