Lub party controller interface (HCI) txheej yog txheej nyias uas thauj cov lus txib thiab cov xwm txheej ntawm tus tswv tsev thiab tus tswj hwm ntawm Bluetooth raws tu qauv pawg. Hauv daim ntawv thov kev sib txuas lus ntshiab, HCI txheej yog siv los ntawm kev thauj mus los xws li SPI lossis UART.
HCI Interface
Kev sib txuas lus ntawm tus tswv (lub khoos phis tawj lossis MCU) thiab Tus Thawj Tswj Hwm (qhov tseeb Bluetooth chipset) ua raws li Tus Thawj Tswj Tswj Kev Sib Tham (HCI).
HCI txhais li cas cov lus txib, txheej xwm, asynchronous thiab synchronous cov ntaub ntawv pob khoom sib pauv. Asynchronous packets (ACL) yog siv rau kev hloov cov ntaub ntawv, thaum synchronous pob ntawv (SCO) yog siv rau lub suab nrog lub mloog pob ntseg thiab Hands-Free Profiles.
Bluetooth HCI ua haujlwm li cas?
HCI muab cov lus txib cuam tshuam rau tus tswj hwm lub hauv paus thiab txuas tus tswj hwm, thiab nkag mus rau cov xwm txheej kho vajtse thiab tswj cov ntawv sau npe. Qhov tseem ceeb no interface muab cov txheej txheem sib xws ntawm kev nkag mus rau Bluetooth baseband peev xwm.HCI muaj nyob thoob 3 ntu, Tus Tswv Cuab - Thauj Txheej - Tus Tswv Tswj. Txhua ntu muaj lub luag haujlwm sib txawv los ua si hauv HCI system.
