我可以在 Raspberry Pi 3 上使用带有 Python 3 的信标工具吗？

Question

I'm trying to use beacontools lib. It works perfectly with python 2.7, but does not with 3.5.

I'm trying to test it with a code provided in examples

import time
from beacontools import BeaconScanner, IBeaconFilter

def callback(bt_addr, rssi, packet, additional_info):
    print("<%s, %d> %s %s" % (bt_addr, rssi, packet, additional_info))

# scan for all iBeacon advertisements from beacons with the specified uuid
scanner = BeaconScanner(callback,
    device_filter=IBeaconFilter(uuid="05f62a3d-f60f-44bc-b36e-2b80fd6c9679")
)
scanner.start()
time.sleep(5)
scanner.stop()

What I have got is:

Traceback (most recent call last): File "/usr/lib/python3.5/threading.py", line 914, in _bootstrap_inner self.run() File "/home/pi/.local/lib/python3.5/site-packages/beacontools/scanner.py", lin e 98, in run self.set_scan_parameters() File "/home/pi/.local/lib/python3.5/site-packages/beacontools/scanner.py", lin e 151, in set_scan_parameters scan_parameter_pkg) _bluetooth.error: (1, 'Operation not permitted')

What is the reason of 'Operation not permitted'? The same code works with python 2.7

Answer 1

I'm not sure about the Python version, but I faced the same issue too. Running the script with sudo worked.

Answer 2

您需要以 root 身份运行 python，例如：

$ sudo python3 <your main.py>
