iOS read system notification

[vaskomichal]

• bleak version: 0.10.0
• Python version: Python 3.7.3
• Operating System: NAME="Raspbian GNU/Linux" VERSION_ID="10" (raspberry pi zero W)
• BlueZ version (bluetoothctl -v) in case of Linux: bluetoothctl: 5.5

Description

I want to create a script which will be read system notification from iPhone. I don't want to create custom characteristics read-write data only read notification like a smart watch on raspberry.

If I understand it correctly it is necessary to set service with UUID 7905F431-B5CE-4E99-A40F-4B1E122D00D0 (The Apple Notification Center Service is a primary service whose service UUID is 7905F431-B5CE-4E99-A40F-4B1E122D00D0) and then set characteristics to 9FBF120D-6301-42D9-8C58-25E699A21DBD (In its basic form, the ANCS exposes three characteristics: Notification Source: UUID 9FBF120D-6301-42D9-8C58-25E699A21DBD (notifiable) )

What I Did

1. sudo bluetoothctl Agent registered
2. Pair raspberry with iPhone
3. Find my iPhone address F8:2D:7C:95:18:6E
4. Copy example enable_notifications.py
5. Changed CHARACTERISTIC_UUID to 9FBF120D-6301-42D9-8C58-25E699A21DBD from apple documentation
6. Changed device address to F8:2D:7C:95:18:6E
7. pip install bleak
8. Enable Bluetooth on my iPhone
9. Run python enable_notifications.py

I assumed that I had to set the service id UUID 7905F431-B5CE-4E99-A40F-4B1E122D00D0 from apple doc somewhere but I don't find the place in the example.

Here is my response when I try to run it.

 bleak.exc.BleakError: Device with address F8:2D:7C:95:18:6E was not found.

Did I forget something? And If I need it how is it possible to set service uuid ?

Here is my source code
