在 Python 中可以使用`pybluez`库实现蓝牙数据的接收和发送。以下是一个示例代码，展示了如何实现一个简单的蓝牙服务器和客户端程序。 #### 蓝牙服务器端代码 ```python import bluetooth server_sock = bluetooth.BluetoothSocket(bluetooth.RFCOMM) server_sock.bind(("", bluetooth.PORT_ANY)) server_sock.listen(1) port = server_sock.getsockname()[1] uuid = "1e0ca4ea-299d-4335-93eb-27fcfe7fa848" bluetooth.advertise_service(server_sock, "SampleServer", service_id=uuid, service_classes=[uuid, bluetooth.SERIAL_PORT_CLASS], profiles=[bluetooth.SERIAL_PORT_PROFILE]) print(f"Waiting for connection on RFCOMM channel {port}") client_sock, client_info = server_sock.accept() print(f"Accepted connection from {client_info}") try: while True: data = client_sock.recv(1024) if not data: break print(f"Received: {data.decode()}") # 发送响应数据 response = "Message received" client_sock.send(response.encode()) except OSError: pass print("Disconnected.") client_sock.close() server_sock.close() ``` #### 蓝牙客户端代码 ```python import bluetooth target_address = "XX:XX:XX:XX:XX:XX" # 替换为实际的蓝牙设备地址 port = 1 sock = bluetooth.BluetoothSocket(bluetooth.RFCOMM) try: sock.connect((target_address, port)) print("Connected to the server") # 发送数据 message = "Hello, server!" sock.send(message.encode()) # 接收响应 response = sock.recv(1024) print(f"Received response: {response.decode()}") except bluetooth.btcommon.BluetoothError as err: print(f"Bluetooth error: {err}") finally: sock.close() ``` ### 代码解释 - **服务器端**：创建一个蓝牙套接字并绑定到一个端口，开始监听连接。当有客户端连接时，接收客户端发送的数据并发送响应。 - **客户端**：创建一个蓝牙套接字并连接到服务器，发送数据并接收服务器的响应。
