Subject: [Bluez-users] reconnect if a remote device quits

Hello everybody

I connect from a PC to another like this:
sock = socket(...)
bind(sock, ...)
connect(sock, ...)
// here the data is exchanged


I now wish to automatic reconnect if the other PC closes the connection
(reboot for example), so I do:

while(true)
{
sock = socket(...)
bind(sock, ...)
connect(sock, ...)
// here the data is exchanged until the remote device quits
sleep(a little);
}

this works fine. but actually i expected this to be enough:

sock = socket(...)
bind(sock, ...)
while(true)
{
connect(sock, ...)
// here the data is exchanged
sleep(a little);
}

but this won't reconnect...
why is socket() and bind() required again? don't they stay the same if I
try to connect to the same bluetooth device again?


regards
Marco

you need to do the full stuff, because close() means closed.
