3.1.4 Higher-Layer Triggered Events

To successfully establish a connection, the protocol relies on three higher-layer events:

  1. A higher layer publishes advertisement IE content which causes a device to be discoverable to proximate devices.

  2. A higher-layer initiates searching for proximate devices which causes Probe Requests to be sent to proximate devices. In reply, Probe Responses are received from the proximate devices and these contain the advertisement IEs for the devices.

  3. A higher-layer selects a proximate device to connect with which causes the sending and receiving of Connection data.
