The host controller interface (HCI) wosanjikiza ndi wosanjikiza woonda womwe umanyamula malamulo ndi zochitika pakati pa zowongolera ndi zowongolera za Bluetooth protocol stack. Mu pulogalamu yapaintaneti yoyera, wosanjikiza wa HCI umakhazikitsidwa kudzera mu protocol yamayendedwe monga SPI kapena UART.
Chithunzi cha HCI
Kulankhulana pakati pa Host (kompyuta kapena MCU) ndi Host Controller (chipset chenicheni cha Bluetooth) kumatsatira Host Controller Interface (HCI).
HCI imatanthawuza momwe malamulo, zochitika, asynchronous ndi synchronous data paketi amasinthidwa. Mapaketi a Asynchronous (ACL) amagwiritsidwa ntchito kusamutsa deta, pomwe mapaketi a synchronous (SCO) amagwiritsidwa ntchito pa Voice yokhala ndi Headset ndi Mbiri Zaulere Pamanja.
Kodi Bluetooth HCI imagwira ntchito bwanji?
HCI imapereka mawonekedwe olamulira kwa olamulira a baseband ndi manejala wamaulalo, ndi mwayi wopeza mawonekedwe a hardware ndi zolembera zowongolera. Kwenikweni mawonekedwewa amapereka njira yofananira yopezera mphamvu za Bluetooth baseband.HCI ilipo pazigawo za 3, Host - Transport Layer - Host Controller. Chigawo chilichonse chili ndi ntchito yosiyana mu dongosolo la HCI.
Feasycom panopa zigawo kuti kuthandiza Bluetooth HCI:
