With WCL library, is 1:n communication possible?
It seems that samples in wcl have only 1:1 s/c.
Thank a lot.

Hello,
You mean send from PC to more than 1 device? Yes, its possible. Take a look on ProximitySender demo. If you want to use wclClient/wclOPPClient/wclFTPClient instead of ProximitySender then you have to use 1 client per one connected device.

I mean that s/c model have a server and more than one clients.
BlueChatClient / BlueChatServer is same as 1:1, but no 1:n.
What's wrong?

What is s/c model? Client/Server?
All is absolutely correct, there is nothing wrong. As I wrote use more than 1 client, more than 1 server. Bluetooth is not TCP/IP and each server must listen on different channel with different SDP record.

Yes, s/c means server/client!
For example, is it possible that have a BlueChatServer and more than one BlueChatClient?
If not, how to do it?
Thank a lot.

Yes it is possible. Take a look on MultyBtOppServer demo. In few words: you have to use more than 1 server. 1 per incomming connection.

Yes and No. Bluetooth before 2.0 has limitation to maximum 7 connections. Bluetooth 2.0 and high has no such limitation but usualy HW developers don't expand it. So most dongles can establish only 7 concurrent connections.
