"""
The Bluetooth compile error says something Velxio can answer better.

arduino-pico gates its BT libraries behind a static_assert telling the user to
use the Arduino IDE's "Tools->IP/Bluetooth Stack" menu. In Velxio that menu does
not exist, so the message reads like a setting we forgot to expose rather than
what it is: the CYW43439's Bluetooth side is not emulated at all.
