- Fix: the Bluetooth MIDI section no longer disappears when the radio comes up a moment after boot. The hub used to check the Bluetooth radio only once at startup; on a Pi 3 B+ (whose Bluetooth firmware loads slightly later) that check could land before the radio finished powering on, hiding the Scan button for the whole session even though Bluetooth was actually fine. The radio is now re-checked each time you open the Add overlay, so the section reappears on its own once the radio is up — no reboot needed. (The check stays read-only while a device is connected; it never disturbs a live BLE link.)
