回溯寫入帳戶金鑰
如果 Looker 透過傳統方式 (例如透過藍牙設定) 執行配對,而非透過快速配對進入點,則不會寫入供應商外掛程式的帳戶金鑰。在這種情況下,即使使用快速配對裝置,使用者也無法查看或使用任何快速配對功能。為了讓使用者享有「快速配對」的好處,供應商可以在配對完成後,立即使用靜音訊息金鑰撰寫帳號。
- 如果供應器繫結時,不會進行快速配對流程,則允許透過金鑰式配對方法寫入新的帳戶金鑰,時間最長為一分鐘。在這段期間,你只會寫入一個帳戶金鑰。
- RFCOMM 版本建立完成後,供應器應透過 Message Stream 將模型 ID 和 BLE 位址傳送至 Seeker,此時 Looker 就會建立 GATT 連線,並啟動金鑰配對配對程序。
- 如果收到含有旗標位元 3 設定的「原始要求」,提供者應驗證已繫結裝置的 BR/EDR 位址是否與要求中所含的內容相同。如果不是,請拒絕要求。
- 由於裝置已繫結,BR/EDR 保證與密碼金鑰驗證(程序中的步驟 8 - 17)就會略過,而共用者建立共用密鑰後,系統會直接將帳戶金鑰寫入供應器。
