python实现数据获取代码
以下是使用bleak库获取特定mac的ble设备广播出来的原始数据的Python代码:
```python
import asyncio
from bleak import BleakScanner
async def scan_for_device(mac_address):
device_data = None
while device_data is None:
devices = await BleakScanner.discover()
for d in devices:
if d.address == mac_address:
device_data = d
break
return device_data
async def main(mac_address):
device_data = await scan_for_device(mac_address)
async with BleakScanner() as scanner:
async with scanner.connect(device_data.address) as conn:
while True:
data = await conn.read_gatt_char(0x0010)
print(data)
if __name__ == "__main__":
mac_address = "00:11:22:33:44:55" # replace with your target device's mac address
loop = asyncio.get_event_loop()
loop.run_until_complete(main(mac_address))
```
在这个代码中,我们使用BleakScanner来扫描可用的BLE设备,然后连接到特定的设备,最后读取GATT特征的值。在这个示例中,我们读取的特征是0x0010。你可以将它替换为你需要读取的特征的UUID。
