Bluetooth serial port module imachokera ku Serial Port Profile (SPP), chipangizo chomwe chimatha kugwirizanitsa SPP ndi chipangizo china cha Bluetooth chotumizira deta, ndipo chimagwiritsidwa ntchito kwambiri pazida zamagetsi ndi ntchito za Bluetooth.
Monga gawo lolumikizirana opanda zingwe, gawo la Bluetooth serial port lili ndi mawonekedwe osavuta komanso osavuta kugwiritsa ntchito. Ngati wopanga atengera ophatikizidwa Bluetooth siriyo doko module + MCU kupanga zinthu ndi Bluetooth ntchito, zamagetsi opanga mankhwala / akatswiri mosavuta kupereka zinthu zamagetsi ndi MCU siriyo madoko popanda akatswiri ndi luso Bluetooth chitukuko chidziwitso. Kuchepetsa kwambiri ndalama za kafukufuku ndi chitukuko cha kampani ndi ndalama zogwirira ntchito, komanso kuchepetsa chiopsezo cha chitukuko.
The Bluetooth chosalekeza doko gawo amazindikira kulekana kwa MCU chitukuko ndi Bluetooth ntchito chitukuko, amene kwambiri amachepetsa vuto la chitukuko Bluetooth mankhwala, bwino bata ndi liwiro la chitukuko cha mankhwala, kufupikitsa mkombero chitukuko mankhwala, ndi Imathandizira nthawi msika.
Pali zovuta zina zomwe mungafune kudziwa:
1. Kodi gawo la Bluetooth serial port module lingathe kufalitsa mawu?
Bluetooth serial port module imachokera ku protocol ya Bluetooth ndipo imagwiritsa ntchito SPP, yomwe ndi pulogalamu ya serial port. Ntchito zina monga zomvera za A2DP sizimathandizidwa. Koma USB adaputala Bluetooth (dongle) ali ntchito zosiyanasiyana, monga kusamutsa wapamwamba, pafupifupi siriyo doko, mawu ndi zina zotero.
2. Kodi ndiyenera kumvetsetsa Bluetooth protocol ndikugwiritsa ntchito gawo la serial port?
Ayi, ingogwiritsani ntchito gawo la Bluetooth serial port ngati cholumikizira chowonekera. Pambuyo polumikizana ndi gawo la Bluetooth serial port pakompyuta kapena foni yam'manja, mutha kutsegula doko lofananira la Bluetooth ndi gawo la doko la Bluetooth kudzera mu pulogalamu yofunsira kuti mulankhule. Ma module a Bluetooth amatha kulumikizidwa ndi zotumphukira zina ndi doko la serial, monga microcontroller kapena kompyuta ina.
3. Momwe mungayesere ngati gawo la doko la Bluetooth ndilabwinobwino?
Choyamba perekani mphamvu ku gawo la Bluetooth (3.3V), kenako TX ndi RX yachidule, phatikizani gawo la doko la Bluetooth kudzera pakompyuta kapena foni yam'manja, ndiyeno mutha kutumiza ndikulandila deta kudzera pa pulogalamu ya doko, kuti muthe yesani ngati Bluetooth serial port module ndiyabwinobwino.
Kuti mumve zambiri, chonde omasuka kulumikizana ndi Feasycom sales Team.
