This approach is insufficient for modern real-time applications where a high-priority sensor alert (BLE notification) may be queued behind a low-priority bulk firmware update (ACL transfer). We propose , a driver topology that implements a "Top" hierarchy policy. This policy mandates that the driver’s entry point (the "top" of the stack) dictates the scheduling logic, ensuring that QoS requirements defined by the user application propagate down to the hardware transport layer without obstruction.
