下面是一份代码供参考:
```python
import bluetooth
import time
target_name = "your_bluetooth_device_name"
target_address = None
while True:
nearby_devices = bluetooth.discover_devices()
for mac_address in nearby_devices:
if target_name == bluetooth.lookup_name(mac_address):
target_address = mac_address
break
if target_address is not None:
print("Found target bluetooth device with address ", target_address)
while True:
try:
sock = bluetooth.BluetoothSocket(bluetooth.RFCOMM)
sock.connect((target_address, 1))
print("Bluetooth Device connected")
# 进行你需要的操作
time.sleep(5) # 等待五秒钟
sock.close()
print("Bluetooth Device disconnected")
break
except:
print("Cannot connect to the device. Try again...")
time.sleep(5) # 等待五秒钟再次尝试连接
else:
print("Could not find target bluetooth device nearby. Trying again...")
time.sleep(5) # 等待五秒钟再次扫描
```
这份代码会不断扫描周围的蓝牙设备,如果找到了目标设备,会尝试连接并进行你需要的操作。如果连接失败,会等待五秒钟再次尝试连接。如果找不到目标设备,会等待五秒钟再次扫描。
请注意,这份代码只是一份简单的示例代码,你需要根据你的实际需求进行修改。
