I-host controller interface (HCI) umaleko ngumaleko obhityileyo othutha imiyalelo kunye neziganeko phakathi komkhosi kunye nezinto zokulawula ze-Bluetooth protocol stack. Kwinkqubo yenkqubo yenethiwekhi ecocekileyo, i-HCI layer iphunyezwa ngeprotocol yezothutho efana ne-SPI okanye i-UART.
HCI Interface
Unxibelelwano phakathi koMamkeli (ikhompyutha okanye i-MCU) kunye ne-Host Controller (eyona Bluetooth chipset) ilandela i-Host Controller Interface (HCI).
I-HCI ichaza indlela imiyalelo, iziganeko, i-asynchronous kunye ne-synchronous data packets zitshintshwa. Iipakethi ze-Asynchronous (ACL) zisetyenziselwa ukudluliselwa kwedatha, ngelixa iipakethi ze-synchronous (SCO) zisetyenziselwa i-Voice kunye ne-Headset kunye neeProfayili ze-Hands-Free.
Isebenza njani iBluetooth HCI?
I-HCI inikezela nge-interface yomyalelo kumlawuli we-baseband kunye nomphathi wekhonkco, kunye nokufikelela kwisimo se-hardware kunye neerejista zokulawula. Ngokusisiseko olu jongano lubonelela ngendlela efanayo yokufikelela kwi-Bluetooth baseband capabilities.I-HCI ikhona kuwo onke amacandelo e-3, i-Host -Layer yezoThutho - i-Host Controller. Icandelo ngalinye linendima eyahlukileyo yokudlala kwinkqubo yeHCI.
I-Feasycom okwangoku ineemodyuli ezixhasa iBluetooth HCI:
Umzekelo: FSC-BT825B
- Inguqulo yeBluetooth: Bluetooth 5.0 imowudi ezimbini
- Ubungakanani: 10.8mm x 13.5mm x 1.8mm
- Iiprofayili: SPP, BLE (Standard), ANCS, HFP, A2DP, AVRCP, MAP(uyazikhethela)
- Ujongano: UART, PCM
- Iziqinisekiso:FCC
- Amanqaku abalulekileyo: I-Bluetooth 5.0 i-Dual-Mode, ubungakanani obuncinci, ixabiso elisebenzayo
