If you are using iTerm2, you need to ensure the terminal itself has permission to Bluetooth.
Open System Settings (or System Preferences).
Go to Privacy & Security > Bluetooth and Grant Access to iTerm2.
python -m venv .venv

An Organizationally Unique Identifier (OUI) is a 24-bit (three-byte) number, managed by the IEEE, that uniquely identifies a manufacturer or organization for network devices, forming the first half of a device's MAC address to ensure global uniqueness
The uuid.UUID class in Python strictly validates strings against the RFC 4122 standard. Specifically, it looks for a "version" digit at a specific position in the string.
Why it's failing In a standard UUID, the first digit of the third group (e.g., xxxx-xxxx-Nxxx-xxxx) must be a number from 1 to 5 (representing the version).
Looking at your data:
D5D93B6E-C324-FD7B... -> The version digit is F.
6ADBBD89-CBFF-0FE8... -> The version digit is 0.
Since F and 0 are not valid RFC 4122 versions (1-5), Python throws a ValueError: badly formed hexadecimal UUID string.
