added bt 5.1 support

[Simon128]

Hi, I had the same issue like #7 for a BT 5.1 device. So I've added support for that. Check it out :)

Thanks!
@x2es could we merge it in?

If there is no response from upstream, maybe it's time to fork the project then?

FYI In latest Arch Linux / Fedora installations it seems to be SlaveLongTermKey so this PR unfortunately doesn't work on such systems. Altough it was a simple fix to get it working, great work!

Is there any fork that works with BLE devices?

To make things worse:

https://github.com/bluez/bluez/blob/6fc599e334cead9cbd014f7830753bc28ee5868b/src/adapter.c#L4100

Later releases will change the key name to "PeripheralLongTermKey"

And I just checked my /var/lib/bluetooth info files, all three variants are there:

• LongTermKey
• SlaveLongTermKey
• PeripheralLongTermKey

And they're all different.

This runs for me without the nasty errors of the main branch, but fails to actually sync my devices.

• Orochi V2 (Mouse)
• JBL Extreme 2 (Speaker)

In the /var/lib/bluetooth info files, the JBL speaker has a LinkKey section and the Orochi mouse has Key sections titled IdentityResolvingKey, PeripheralLongTermKey and SlaveLongTermKey.

I can provide more info and testing if that's helpful.

Not a fork, but a script to similar effects
