bluetooth pairing keys install

[bam80]

I would like to install pre-existing bluetooth pairing keys with Ansible to make BT mouse work after system install.
Is it possible?

How do you copy the keys without Ansible? Post a script.

[bam80]

I don't have such a script, but here is the code to copy BLE keys from Linux to Windows:

Quote: "Sync Bluetooth for dual-boot Linux and Windows"

If you install bt-dualboot the simple task below should do the job

- hosts: all
  tasks:
    - command: 'sudo bt-dualboot --sync-all'

Let me know if this works for you. We can add it to the role then.

[bam80]

What I can see from the doc, --sync-all is suitable for syncing all the devices between Linux and Windows.
What I need is:

• pull the keys from existing Linux hosts as a backup measure
• sync the backed up keys with Linux hosts needed

[vbotka]

I see. Unfortunately, I have no Linux/Windows dual-boot to test it. Still the same Let me know if bt-dualboot is working for you. Feel free to submit a PR.

the syncing between Linux and Windows works fine, I tested it

[vbotka]

Good to know. Feel free to submit a PR.

I thought maybe the measures to gather bt keys as part of other hw info are already exist?
That would be start I guess. And then the copy itself.
I'm not familiar with Ansible architecture enough to say that.

[bam80]

Alternatively, if it possible to forcibly set a key for BT connection, that would be good to know

BT keys are not part of HW info the same way any other keys (ssh, gpg, ...) are not.

You can ask this in the bt-dualboot project.

OK, so the idea is to handle it the same way as WiFi key then.
IIUC, the script above does reading the key from Linux configs, we would need to rework it so it could write instead.
I'm not a python programmer so some help would be welcomed.

There are also many approaches supporting Windows to Linux sync, those might be more interesting for our case as they support "write" to Linux from exported file:

We would need to investigate which of the projects suits best for our needs.
