macOS 12 Arm M1 MAX script aborts #768
Description
- bleak version: 0.12.1
- Python version: 3.9
- Operating System: macOS 12 Arm M1 MAX and macOS (probably version 12) standard
- BlueZ version (
bluetoothctl -v) in case of Linux: -
Description
I would like to run the program on the new architecture - macOS 12 ARM M1, unfortunately the program crashes. It works correctly on WIN10 and macOS Intel.
What I Did
In order to locate the error I try to run an example from the repository - disconnect_callback.py. In the example I changed only the debug level (line 7):
import asyncio
from bleak import BleakScanner
from bleak.backends.device import BLEDevice
from bleak.backends.scanner import AdvertisementData
import logging
logging.basicConfig(format='[%(name)s - %(levelname)s] %(message)s', level=logging.DEBUG)
def simple_callback(device: BLEDevice, advertisement_data: AdvertisementData):
print(device.address, "RSSI:", device.rssi, advertisement_data)
async def run():
scanner = BleakScanner()
scanner.register_detection_callback(simple_callback)
while True:
await scanner.start()
await asyncio.sleep(5.0)
await scanner.stop()
loop = asyncio.get_event_loop()
loop.run_until_complete(run())
Running the example on macOS ARM M1 (standard, not MAX) then I get the message:

The program supposedly works, but it does not find any device, even though there are a lot of devices with BLE around. I have seen similar problems that are solved by migrating to the latest version of the library, tomorrow i will update library, but...
I am now trying to run the same example on macOS 12 ARM M1 MAX:
In this case, the program crashes immediately. You can see that the program starts because the DEBUG log is displayed, but after a while it is aborted without any message. And it's strange, different behavior than before - I couldn't find a similar issues on the forum.
I found on the forum that macOS 12 needs a library update - fix in version 0.14.0 and higher but script running on MAX version is aborted immediately ?
If I am duplicating the problem I apologize but I have limited access to these two machines for testing so I would like to make sure if it is the fault of the library version possibly try something new. Tomorrow I will update the library to the latest version and see if it worked.
