Hi
I used open function to open bluetooth port on
MacOS 10.5.1. (configured bluetooth port as RS-232)
My code is as below
int fd = -1;
fd = open(Bluetooth port
path,O_RDWR + O_NOCTTY + O_NONBLOCK + O_EXLOCK); // it open port
successfully
if(fd == -1)
printf("\nPort open failed..");
else
{
printf("\nPort successfully opened..);
close(fd);
fd = -1;
}
fd = open(Bluetooth port path,O_RDWR + O_NOCTTY +
O_NONBLOCK + O_EXLOCK); // it blocks (no return).
I do operation in sequence open then close then
again open immediately...
first time it open successfully .. second time
it block in open. (open function block) ...after that open blocks all the
time
Note :: Same thing works on MacOS 10.4
successfully
What may be the problem ?
