在Python中,控制蓝牙音响通常会使用`pybluez`库,这是一个用于访问蓝牙设备的库。以下是一个简单的例子,展示如何使用Python连接到蓝牙音响并播放音频:
```python
import asyncio
from bleak import BleakClient, BleakScanner
# 扫描蓝牙设备
async def scan_for_bluetooth():
scanner = BleakScanner()
devices = await scanner.discover()
for d in devices:
print(f"Name: {d.name}, Address: {d.address}")
# 假设你找到了一个设备名为"BluetoothSpeaker"
target_device_address = "AA:BB:CC:DD:EE:FF" # 替换为你的设备地址
return target_device_address
# 连接到蓝牙音响并发送命令(这里假设有个特征ID是0x0001)
async def connect_and_play(device_address):
async with BleakClient(device_address, timeout=10.0) as client:
# 假设音响有一个服务UUID和特征UUID用于播放音乐
service_uuid = "00001101-0000-1000-8000-00805F9B34FB"
characteristic_uuid = "00002A06-0000-1000-8000-00805F9B34FB"
# 发送播放命令,具体格式可能因音响厂商而异
await client.write_gatt_char(characteristic_uuid, b'\x01\x02\x03') # 示例数据
# 主程序
async def main():
device_address = await scan_for_bluetooth()
if device_address:
try:
await connect_and_play(device_address)
print("Successfully connected and played audio.")
except Exception as e:
print(f"Error: {e}")
else:
print("No Bluetooth speaker found.")
if __name__ == "__main__":
asyncio.run(main())
```
请注意,这个示例是基于假设的,实际的蓝牙设备和服务、特征UUID可能会有所不同。在使用前,你需要查找你的蓝牙音响的确切UUID。另外,不同设备的通信协议和命令格式也可能不同。
