Python lightblue : "AttributeError: module 'lightblue' has no attribute 'finddevices'"

Question

.

Hi everyone, hope you're doing well!

I am trying to write a Python (3.8.9) script so that my computer detects every Bluetooth device it can find and provides me with the list of devices it has found. Then, I installed pybluez and lightblue with

pip3 install pybluez

and

pip3 install python-lightblue

python-lightblue has the version 1.0.3. Now, here's my code :

import bluetooth

def scan():
    print("Scanning for bluetooth devices:")
    devices = bluetooth.discover_devices(lookup_names = True, lookup_class = True)
    number_of_devices = len(devices)
    print(number_of_devices," devices found")
    for addr, name, device_class in devices:
        print("\n")
        print("Device:")
        print("Device Name: %s" % (name))

When I run this, I get the following mistake :

Traceback (most recent call last):
  File "bluetooth_detect.py", line 16, in <module>
    scan()
  File "bluetooth_detect.py", line 5, in scan
    devices = bluetooth.discover_devices(lookup_names = True, lookup_class = True)
  File "/Users/<my_name>/Library/Python/3.8/lib/python/site-packages/bluetooth/macos.py", line 12, in discover_devices
    devices = lightblue.finddevices(getnames=lookup_names, length=duration)
AttributeError: module 'lightblue' has no attribute 'finddevices'

Yet, when I check the documentation on the Internet, the module lightblue does have the attribute finddevices, and I can't find any mention of this problem on another forum (maybe I didn't look up long enough ?)

Would anyone have any idea ? Thank you in advance ! :-)
