Rafu ya Itifaki ya Bluetooth ni nini
Rafu ya Bluetooth, pia inajulikana kama Rafu ya itifaki ya Bluetooth, ni mkusanyiko wa itifaki za programu ambazo vifaa vya Bluetooth hutumia kuwasiliana. Stack ina tabaka kadhaa, kila moja inawajibika kwa kazi maalum. Tabaka hizi hufanya kazi pamoja ili kuanzisha na kudumisha muunganisho kati ya vifaa viwili au zaidi vya Bluetooth na kuwezesha mawasiliano kati yao. Baadhi ya utendakazi ambazo rafu ya Bluetooth hufanya ni pamoja na ugunduzi wa kifaa, kuanzisha muunganisho na uhamisho wa data. Mifumo na vifaa tofauti vya uendeshaji vinaweza kutumia rafu tofauti za Bluetooth, na itifaki kadhaa tofauti zinaweza kutumika ndani ya kila rafu.
Jinsi ya Kuchagua Ratiba ya Itifaki ya Bluetooth/Moduli ya RF Inayofaa ya Gari
Kwa kawaida, tunapochagua moduli ya Bluetooth Protocol Stack/RF kwa ajili ya programu za gari, pointi zifuatazo zinahitajika kuthibitishwa:
1. Mfumo wa uendeshaji (OS): Android/Linux, nk.
2. Toleo la Kernel
3. Mahitaji ya kiolesura: kama vile UART, SDIO, PCle, n.k.
4. Matukio ya kina ya maombi
