The host controller interface (HCI) layer (HCI) ke lera le tšesaane le tsamaisang litaelo le liketsahalo lipakeng tsa moamoheli le likarolo tsa taolo ea stack ea protocol ea Bluetooth. Ts'ebetsong e hloekileng ea processor ea marang-rang, lera la HCI le kengoa ts'ebetsong ka protocol ea lipalangoang joalo ka SPI kapa UART.
Sesebelisoa sa HCI
Puisano pakeng tsa Moamoheli (khomphutha kapa MCU) le Host Controller (e leng Bluetooth chipset ea sebele) e latela Host Controller Interface (HCI).
HCI e hlalosa hore na litaelo, liketsahalo, lipakete tsa data tsa asynchronous le synchronous li fapanyetsanoa joang. Lipakete tsa Asynchronous (ACL) li sebelisoa bakeng sa phetisetso ea data, ha lipakete tsa synchronous (SCO) li sebelisoa bakeng sa Voice with the Headset le Hands-Free Profiles.
Bluetooth HCI e sebetsa joang?
HCI e fana ka sebopeho sa taelo ho molaoli oa baseband le mookameli oa lihokelo, le phihlello ea maemo a Hardware le lirekoto tsa taolo. Ha e le hantle sebopeho sena se fana ka mokhoa o ts'oanang oa ho fihlella bokhoni ba Bluetooth baseband.HCI e teng ho pholletsa le likarolo tse 3, Host - Transport Layer - Host Controller. E 'ngoe le e' ngoe ea likarolo e na le karolo e fapaneng eo e lokelang ho e bapala tsamaisong ea HCI.
Feasycom hajoale e na le limmojule tse tšehetsang Bluetooth HCI:
