Root cause: Arduino Core 3.x breaks cross-core NimBLE API calls. Calling BLEMidiServer.controlChange() from loop() on Core 1 while NimBLE host runs on Core 0 causes immediate crash. Fix: - Move ble_midi_transport.begin() to ble_init_task on Core 0 - All BLE MIDI sends use queue_cc() (cross-core safe flag setter) - ble_midi_transport.update() processes queued sends on Core 0 - Pin NimBLE-Arduino to v1.4.3 (stable LTS for BLE MIDI) - Keep CONFIG_BT_ENABLED out of sdkconfig.h (causes double-init)
