However, standard CS usage remains tied to per-pair LE asynchronous connection logical transport (LE ACL) connections, which adds initiation overhead, limits concurrent partners, and transfers results over the connection itself. We present a connectionless CS architecture that combines the LE CS Test command with Periodic Advertising with Responses (PAwR).
