Server: Here I declare four BluetoothSockets. Because accept () is a blocking operation, once the connection is successful, it will return to BluetoothSocket, and then continue to wait for the next connection. In this way, we have achieved multiple connections. UUID is the identifier of the server. After obtaining the BluetoothSocket, we can perform related operations to obtain input and output streams. To communicate with each other. by there
