Iyo host controller interface (HCI) layer idenda rakatetepa iro rinotakura mirairo uye zviitiko pakati peanotambira uye controller zvinhu zveBluetooth protocol stack. Mune yakachena network processor application, iyo HCI layer inoitwa kuburikidza neyekufambisa protocol senge SPI kana UART.
HCI Interface
Kukurukurirana pakati peMugamuchiri (kombuta kana MCU) neMutariri Wekugamuchira (iyo chaiyo Bluetooth chipset) inotevera Host Controller Interface (HCI).
HCI inotsanangura kuti mirairo, zviitiko, asynchronous uye synchronous data mapaketi anotsinhaniswa sei. Asynchronous mapaketi (ACL) anoshandiswa kuendesa data, nepo synchronous mapaketi (SCO) anoshandiswa kuIzwi neHeadset uye Maoko Emahara Profiles.
Bluetooth HCI inoshanda sei?
Iyo HCI inopa chinongedzo chekuraira kune baseband controller uye chinongedzo maneja, uye kuwana kune Hardware mamiriro uye kutonga marejista. Zvikurukuru iyi interface inopa yunifomu nzira yekuwana iyo Bluetooth baseband kugona.I HCI iripo muzvikamu zvitatu, iyo Host - Transport Layer - Host Controller. Chimwe nechimwe chezvikamu chine basa rakasiyana rekuita muHCI system.
