Sync Bluetooth Key

Script to copy Bluetooth Key and MAC address of a device from Windows to Linux so that the device can work in both systems without re-paring.

I create this for personal use since bt-dualboot has not yet worked with my Bluetooth LE (Low Energy) devices. I try to keep it as simple as possible so for specific case you might want to check this ArchWiki page first.

Using

1. Pair and connect the device in Linux FIRST

2. Pair and connect the device in Windows

3. Boot to Linux

4. Mount Windows partition

5. Install chntpw on Linux to read registry file

   sudo apt install chntpw 
   

6. Download dbBluetooth.py and requirement.txt and save it to a new folder

7. In this folder, create a virtual environment to install required packages

   python3 -m venv .venv
   source .venv/bin/activate
   pip install -r requirements.txt
   

8. Still in the folder, run script with sudo privileges (to gain access to /var/lib/bluetooth/)

   sudo ./dbBluetooth.py
   

9. Rebooting

   (You can try restart bluetooth service first using systemctl restart bluetooth but in my case the device only works after rebooting)
