Layer olutona oluṣakoso (HCI) jẹ Layer tinrin eyiti o gbe awọn aṣẹ ati awọn iṣẹlẹ lọ laarin agbalejo ati awọn eroja oludari ti akopọ Ilana Bluetooth. Ninu ohun elo ero isise nẹtiwọọki mimọ, Layer HCI ti wa ni imuse nipasẹ ilana gbigbe gẹgẹbi SPI tabi UART.
HCI Interface
Ibaraẹnisọrọ laarin Olugbalejo (kọmputa kan tabi MCU) ati Olutọju Olupese (Petcell Bluetooth gangan) tẹle Olutọju Alakoso (HCI).
HCI n ṣalaye bi awọn aṣẹ, awọn iṣẹlẹ, asynchronous ati awọn apo-iwe data amuṣiṣẹpọ ṣe paarọ. Awọn apo-iwe Asynchronous (ACL) ni a lo fun gbigbe data, lakoko ti awọn apo-iwe amuṣiṣẹpọ (SCO) jẹ lilo fun Ohun pẹlu Agbekọri ati Awọn profaili Ọwọ Ọwọ.
Bawo ni Bluetooth HCI ṣiṣẹ?
HCI n pese wiwo pipaṣẹ si oluṣakoso baseband ati oluṣakoso ọna asopọ, ati iraye si ipo ohun elo ati awọn iforukọsilẹ iṣakoso. Ni pataki ni wiwo yii n pese ọna aṣọ kan ti iraye si awọn agbara baseband Bluetooth. HCI wa kọja awọn apakan 3, Olugbalejo – Layer Transport – Olutọju Gbalejo. Ọkọọkan awọn apakan ni ipa ti o yatọ lati ṣe ninu eto HCI.
