要使用易编程蓝牙控制器,您需要遵循以下步骤:
安装PyBluez
Windows:使用pip安装:
```
pip install pybluez
```
Linux (Ubuntu/Debian):
```
sudo apt-get install libbluetooth-dev
pip install pybluez
```
Mac OS:
```
brew install boost
brew install boost-python3
pip install pybluez
```
搜索附近的蓝牙设备
```python
import bluetooth
def scan_devices():
print("Scanning for Bluetooth devices...")
devices = bluetooth.discover_devices(duration=8, lookup_names=True, flush_cache=True, lookup_class=False)
print(f"Found {len(devices)} devices.")
for addr, name in devices:
print(f"{addr} - {name}")
if __name__ == "__main__":
scan_devices()
```
连接蓝牙设备
```python
import bluetooth
def connect_device(address):
port = 1 Bluetooth RFCOMM ports
try:
sock = bluetooth.BluetoothSocket(bluetooth.RFCOMM)
sock.connect((address, port))
print(f"Connected to {address} on port {port}")
return sock
except bluetooth.btcommon.BluetoothError as err:
print(f"Error connecting: {err}")
return None
if __name__ == "__main__":
address = "XX:XX:XX:XX:XX:XX" Replace with the address of the device you want to connect to
sock = connect_device(address)
if sock:
You can now use the sock object to send and receive data
sock.close()
```
发送和接收数据
```python
import bluetooth
def send_data(sock, data):
try:
sock.send(data)
print(f"Sent: {data}")
except Exception as err:
print(f"Error sending data: {err}")
def receive_data(sock):
try:
data = sock.recv(1024)
if data:
print(f"Received: {data}")
else:
print("No data received")
except Exception as err:
print(f"Error receiving data: {err}")
if __name__ == "__main__":
address = "XX:XX:XX:XX:XX:XX" Replace with the address of the device you want to connect to
port = 1 Bluetooth RFCOMM ports
sock = connect_device(address)
if sock:
send_data(sock, "Hello, Bluetooth!")
receive_data(sock)
sock.close()
```
这些示例代码展示了如何使用PyBluez库来搜索和连接蓝牙设备,以及发送和接收数据。您可以根据自己的需求修改这些代码,以适应不同的蓝牙设备和应用场景。
