Qaybta dekedda serial ee Bluetooth waxay ku salaysan tahay Serial Port Profile (SPP), oo ah aalad abuuri karta xidhiidhka SPP iyo aaladaha kale ee Bluetooth ee gudbinta xogta, waxaana si weyn loogu isticmaalaa aaladaha elegtarooniga ah ee leh shaqooyinka Bluetooth-ka.
Sida moduleka isgaarsiinta guud ee wireless-ka, moduleka dekedda serial ee Bluetooth wuxuu leeyahay sifooyinka horumarinta fudud iyo hawlgal sahlan. Haddii wax soo saaruhu uu qaato moduleka dekeda taxan ee Bluetooth-ka + MCU si uu u horumariyo alaabada leh shaqada Bluetooth-ka, soo-saareyaasha/injineerada alaabada elektiroonigga ah waxay si fudud u bixin karaan badeecadaha elegtarooniga ah ee dekedaha taxanaha ah ee MCU iyaga oo aan lahayn aqoon horumarineed oo Bluetooth ah oo xirfad leh iyo casri ah. Waxay si weyn hoos ugu dhigtay cilmi-baarista iyo kharashka horumarinta ee shirkadda, laakiin sidoo kale waxay hoos u dhigtay khatarta horumarinta.
Qaybta dekedda serial ee Bluetooth waxay xaqiiqsatay kala-soocidda horumarinta MCU iyo shaqada horumarinta Bluetooth, taas oo si weyn u yaraynaysa dhibka horumarinta alaabta Bluetooth, wanaajisa xasilloonida iyo xawaaraha horumarinta alaabta, waxay soo gaabinaysaa wareegga horumarinta alaabta, waxayna kordhisaa wakhtiga suuqa.
Waxaa jira dhibaatooyin qaar laga yaabo inaad rabto inaad ogaato:
1. Moduleka dekedaha taxan ee Bluetooth-ka ma gudbin karaa maqal?
Qaybta dekedda serial ee Bluetooth waxay ku salaysan tahay hab-maamuuska Bluetooth waxayna fulisaa SPP, kaas oo ah codsi deked taxane ah. Codsiyada kale sida codsiyada A2DP lama taageero. Laakiin adabtarada Bluetooth-ka ee USB-ga (dongle) waxa uu leeyahay codsiyo kala duwan, sida wareejinta faylka, deked taxan, cod iyo wixii la mid ah.
2. Miyaan u baahanahay in aan fahmo borotokoolka Bluetooth-ka marka aan isticmaalayo moduleka dekeda taxan?
Maya, kaliya u isticmaal moduleka dekeda taxan ee Bluetooth ka sidii goob taxan oo hufan. Ka dib markaad ku xidho moduleka dekeda taxan ee Bluetooth ka kombayutarka ama taleefanka gacanta, waxaad furi kartaa isku xidhka taxanaha ah ee Bluetooth iyo moduleka dekeda serial ee Bluetooth adoo adeegsanaya barnaamijka codsiga si aad ula xidhiidho. Module-ka Bluetooth-ka waxa lagu xidhi karaa qalabyo kale oo leh deked taxan, sida microcontroller ama kumbiyuutar kale.
3. Sidee loo tijaabiyaa in moduleka dekeda taxan ee Bluetooth uu yahay mid caadi ah?
Marka hore waxaad siisaa awoodda moduleka Bluetooth-ka (3.3V), ka dib TX iyo RX-gaaban, ku dheji moduleka serial port ee Bluetooth adigoo isticmaalaya kumbuyuutarka ama taleefanka gacanta, ka dibna waxaad u diri kartaa oo aad ka heli kartaa xogta adoo isticmaalaya app port-ka, si aad u awooddo. tijaabi bal in moduleka serial port ee Bluetooth uu yahay mid caadi ah.
