Short-Range Wireless Drivers
The host, radio, profile, and endpoint layers behind nearby wireless connections.
Radio and profile are different
A short-range wireless stack includes a radio transport plus profiles or services that describe what connected devices do. The radio driver represents hardware and link behavior; profile layers represent functions such as input or audio.
Pairing is a relationship
Identity, addressing, keys, capabilities, and profile selection form a relationship between nearby devices. A visible radio or discovered device is not the same state as an active application service.
Transport has variable timing
Wireless links coordinate discovery, channel use, power states, retransmission, and endpoint queues. Those mechanisms differ from the higher-level semantics of files, audio streams, or input reports.
Separate evidence
Radio identity, protocol version, profile support, endpoint state, and application session each describe a different layer. Keeping them separate avoids broad compatibility claims based on proximity alone.
Reference facts
- Stack
- Radio transport, protocol, profile, endpoint, and application service.
- State distinction
- Discovery, relationship, active link, profile, and session are not interchangeable.
Questions and answers
Does discovering a wireless device make its service available?
No. Discovery identifies a nearby device; relationship, profile support, link state, and service readiness are separate stages.
Can wireless audio and input share a radio?
They can share radio hardware while exposing separate profiles, endpoints, queues, and software interfaces.
