Layin mai sarrafa mai watsa shiri (HCI) wani sirara ce mai ɗaukar umarni da abubuwan da suka faru tsakanin mai watsa shiri da abubuwan sarrafawa na tari na yarjejeniya ta Bluetooth. A cikin aikace-aikacen sarrafa cibiyar sadarwa mai tsafta, ana aiwatar da Layer HCI ta hanyar ka'idar sufuri kamar SPI ko UART.
HCI Interface
Sadarwa tsakanin Mai watsa shiri (kwamfuta ko MCU) da Host Controller (ainihin chipset na Bluetooth) yana biye da Host Controller Interface (HCI).
HCI tana bayyana yadda ake musayar umarni, abubuwan da suka faru, asynchronous da fakitin bayanai masu aiki tare. Ana amfani da fakitin Asynchronous (ACL) don canja wurin bayanai, yayin da fakiti masu aiki tare (SCO) ana amfani da su don Murya tare da naúrar kai da Bayanan Bayanan Hannun-Kyauta.
Ta yaya Bluetooth HCI ke aiki?
HCI yana ba da umarnin umarni ga mai sarrafa baseband da manajan haɗin gwiwa, da samun damar matsayin kayan aiki da rijistar sarrafawa. Mahimmanci wannan keɓancewa yana ba da tsari iri ɗaya don samun damar damar haɗin ginin Bluetooth. HCI yana wanzuwa a cikin sassan 3, Mai watsa shiri - Layer Transport - Mai Gudanarwa. Kowane ɓangaren yana da rawar da zai taka a cikin tsarin HCI.
Feasycom a halin yanzu yana da kayayyaki masu goyan bayan HCI na Bluetooth:
