Hey @digitalbirdo,

Are you still supporting LinkkeySync? I read on a forum that instead of Link Keys, BT 4.0 devices actually use EDIV, IRK and LTK. I didn't test this because this whole process is too time consuming for the setting to be lost if something where to happen (if I need to re-pair the devices due to some issue).

Anyway, I'm at a loss on how to succeed on this endeavor of dual booting my 4.0 BT devices. Any assistance would be greatly appreciated!

Thank you.

Regards

Moue paired & working, but keys are empty

Success, special thanks!
System is: OS X 10.11.6, windows 10; BCM94352HMB
Three devices to switch between dual systems can be used without re-pairing.
Device 1: Microsoft Sculpt Comfort Mouse
Device 2: philips 24in with Bluetooth audio display
Device 3: iphone SE

Dear ,

Thanks so much for your guide.

could you tell me how to use asus BT400 and apple keyboard to change OS on clover.

i install mac os 10.12 and windows 7 too.

I just made my BLE MS Designer mouse work on both Windows and macOS.
Steps are as follows:

• Pair on macOS first, and then on Windows.
• Export HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\BTHPORT\Parameters\Keys\{bluetooth adapter MAC}\{BLE device MAC} to a reg file and reboot into macOS.
• Disable Bluetooth.
• Modify /Library/Preferences/com.apple.Bluetooth.plist replacing all instances of the previous MAC address of the BLE device with the new one, and also modify /private/var/root/Library/Preferences/blued.plist (up to Sierra) or /private/var/root/Library/Preferences/com.apple.Bluetooth.plist (High Sierra onwards) as follows:
  -- Expand SMPDistributionKeys, and expand again the dictionary named after the bluetooth adapter MAC, you'll find one sub-dictionary for each BLE device, named after their MACs. Replace the MAC of the device you're dealing with with the new one, and expand that dictionary.
  -- LTK, RAND, IRK, address and EDIV need to be changed. They're respectively LTK, ERand, IRK, Address and EDIV from the reg file, nothing needs to be endian swapped except for the EDIV (as an example, "EDIV"=dword:000080b4 in the reg file means the macOS EDIV is b480) and the Address (as an example, "Address"=hex(b):46,78,f9,ba,1a,db,00,00 in the reg file means the macOS Address is db1abaf9 7846).
• Save the files and reboot, re-enable Bluetooth.

I have this error

blued.plist.zip
File "/Users/fabien/Desktop/BT-LinkkeySync.py", line 40, in
print(" Bluetooth 2.0: "+str(len(pl["LinkKeys"].keys()))+ " Links keys found")
KeyError: 'LinkKeys'

Thanks for your aid

I import btkeys.reg in windows but mouse still does not work. What is the reason.

I just did this manually and it was pretty straightforward.

From a paired device in Windows 10 (the Bose 700s, which interestingly support LE but were not paired by LE), I exported the link key data, changed the endianness to MacOS, then replaced this in the Mojave /private/var/root/Library/Preferences/com.apple.bluetoothd.plist (I used a hex editor to find and replace the existing paired key with Windows').

The only gotcha was that I had to not only disable Bluetooth before modifying the plist file, but also perform a system reboot before starting Bluetooth again. Otherwise, something was reverting the key change to the plist file. I tried to see if I could figure out which specific service was doing this but didn't have any luck.

I appreciate that perhaps replacing the key on Windows is easier than the above but wanted to share that it is indeed possible nevertheless.

I've ran on 10.13 but the key has nothing in it.
therefore cannot import on windows

Is it possible to support Linux OS as well?

It does not work on my computer with macOS 12 Monterey, I can't find /private/var/root/Library/Preferences/com.apple.bluetoothd.plist.

I'm currently using MacOS Majave 10.14 beta.

Please update for this device!

Any chance of updating this to work in Catalina?

In line 15 of the python script I would propose changing true into True, because otherwise you run into an syntax error if you change False against true. A simple-hearted as me made that experience ...
