1, that a Bluetooth device pairing is not possible, or that can not be directly connected to skip pairing, right?
2, I use the company's own research and development of our logistics machine equipment, I was learning Bluetoothchat demo, but the demo is used to manage these three threads, I want to ignore the thread, but there will always be a problem, that is return data when a client sends data to the server, the server is able to receive data, but I would like to receive the data at the server to the client again, this time the client is not receiving the

In fact, this process I know, I now have a little do not understand, please cattle little guidance about:

Client creates a connection request, the request Server instance of an object through a call to connect method BluetoothSocket received the request to call the accept method by BluetoothServerSocket Server instance object and returns a BluetoothSocket object returnSocket, in this returnSocket Demo is entrusted to a thread, read and write input and output streams in the thread. A process is this request as Client B, and the first send a data "This is A" to B, when B receives this data, you need to return a piece of data to A, for example, "has received a letter from A's" , and this is how data is parsed A? I hope Daniel guidance
