Unable to Discover/Connect to iOS Devices

[stevennyman]

• bleak version: 0.4.0
• Python version: 3.7.3
• Operating System: Windows 10 version 1809

Description

I tried running the discover.py example, and my iOS 12.1.4 iPhone SE was not recognized. I had the Bluetooth menu open on the device so it would be discoverable.

I tried getting the device's services by using the get_services.py example with the iOS device's Bluetooth address filled into the script. The iOS device was opened to the Bluetooth menu. The device was not found. Traceback for get_services.py:

Traceback (most recent call last):

Note that when typically attempting to pair Windows and iOS a code and confirmation prompt are displayed on both devices. I'm not sure if this is required for iOS pairing.

Bleak is a Bluetooth Low Energy communication package, only capable of communicating to devices exposing services via that technology. Pairing with you iOS device would typically be done via regular Bluetooth, so this package is regrettably not capable of helping you.

[stevennyman]

The documentation for the API I would like to work with specifically mentions Bluetooth LE: https://developer.apple.com/library/archive/documentation/CoreBluetooth/Reference/AppleNotificationCenterServiceSpecification/Introduction/Introduction.html. @hbldh

Ok, apparently I was premature in closing this. I did not understand what you actually wanted to do.

I can detect multiple iOS devices using the discover method, but strangely enough not my own. I was also capable of connecting to an iOS device and request some data, but not from all characteristics, so I think there needs to be some modifications in the code to allow for handling access.

I will try to find out why all devices does not show up.

It is possible to connect and get services from iOS devices with Bleak now. This is output from service_explorer.py example:

I have not succeded in pairing with one yet though (I think it requires PIN codes and such like, which Bleak does not handle yet), so some characteristics are off limits. However, I will close the issue since it is possible at least.

[athar1001]

i am trying to connect IOS device with service_explorer.py but getting timeout error can you please help on this issue.

[hbldh]

@athar1001 Try setting the timeout to a higher value. Change line 28 of service_explorer.py to

async with BleakClient(address, timeout=30) as client:

Did you fix the problem? I paired my device with raspberry but still I had the same error Device with address XX:XX:XX:XX:XX:XX was not found. was not found.
