Bluetooth Low Energy (BLE) devices pairing keys are managed differently than standard bluetooth devices.
Since I don't own any BLE device I'am unable to add support for them.

If you have a BLE device and you want their support to be implemented, you can help by posting the info i need:

The info file of the BLE device in linux:

sudo cat "/var/lib/bluetooth/${bt_controller_macaddr}/${bt_device_macaddr}/info"

• where ${bt_controller_macaddr} is the MAC Address of the bluetooth controller and ${bt_device_macaddr} is the MAC Address of the BLE device.

The exported registry file of windows containing the BLE device credentials.

To obtain this file:

• install chntpw
  sudo apt install chntpw
• Mount the windows partition
• Locate the SYSTEM hive file in the windows partition, usually is something like "<windows_mount_point>/Windows/System32/config/SYSTEM"
• Export the keys
  sudo reged -x "<windows_mount_point>/Windows/System32/config/SYSTEM" "HKEY_LOCAL_MACHINE\SYSTEM" "ControlSet001\Services\BTHPORT\Parameters\Keys" "/tmp/exported_keys.reg"
• print the exported registry
  cat "/tmp/exported_keys.reg"

I need these in order to compare the formats between the linux info file and the exported windows registry file.

Please do not hesitate to post here for any questions or difficulty you may have about this issue.

Thanks and best regards!
