Dear all
When i bind a rfcomm tty socket, Could i serve mulitple connections
at the same time? And how about rfcomm raw socket? if the answer is no,
that mean i need to open a new channel to listen.
Also , could i connect the rfcomm channel in the same computer?
best regard
Mike,Lee

this works if the two client connections are from different devices. If
they are coming from the same device then this won't work and you need a
second server on a different channel.

Sorry for my bad english, may be i describe more.
I am now writing a server program to accept 2 rfcomm connections. I
found that it is not possible to accept 2 connections with same channel.
Why i ask this because, in tcp socket, a server create a socket with
e.g. 80 port. It can then accept multiple connections with the same port
number. The behavior is different between channel and socket.
So, if i want to make multiple connections with rfcomm, i need to
bind, listen and accept in another rfcomm socket. Does this thinking
correct?
I hope i can describe more clearly.

be more specific in what you are trying to do. I can't follow you.
