Tsarin tashar tashar jiragen ruwa ta Bluetooth yana dogara ne akan Serial Port Profile (SPP), na'urar da za ta iya ƙirƙirar haɗin SPP tare da wata na'urar Bluetooth don watsa bayanai, kuma ana amfani da ita sosai a cikin na'urorin lantarki masu ayyukan Bluetooth.
A matsayin babban tsarin sadarwa mara waya, tsarin tashar tashar jiragen ruwa ta Bluetooth yana da halayen haɓaka mai sauƙi da sauƙin aiki. Idan masana'anta sun rungumi tsarin tashar tashar jiragen ruwa na Bluetooth + MCU don haɓaka samfura tare da aikin Bluetooth, masu haɓaka / injiniyoyi za su iya samar da samfuran lantarki cikin sauƙi tare da tashar jiragen ruwa na MCU ba tare da samun ƙwararru da ƙwararrun ilimin haɓaka Bluetooth ba. Mahimmanci ya rage farashin bincike da ci gaban kamfanin da farashin aikin yi, amma kuma ya rage haɗarin ci gaba.
Tsarin tashar tashar jiragen ruwa na Bluetooth yana fahimtar rabuwar ci gaban MCU da aikin haɓaka Bluetooth, wanda ke rage wahalar haɓaka samfuran Bluetooth sosai, yana inganta kwanciyar hankali da saurin haɓaka samfuran, yana rage sake zagayowar haɓaka samfuran, da haɓaka lokacin kasuwa.
Akwai wasu matsalolin ƙila kuna so ku sani:
1. Za a iya Bluetooth serial port module aika audio?
Tsarin tashar tashar jiragen ruwa ta Bluetooth yana dogara ne akan ka'idar Bluetooth kuma yana aiwatar da SPP, wanda shine aikace-aikacen tashar jiragen ruwa. Sauran aikace-aikacen kamar aikace-aikacen A2DP mai jiwuwa ba su da tallafi. Amma adaftar Bluetooth na USB (dongle) yana da aikace-aikace iri-iri, kamar canja wurin fayil, tashar tashar jiragen ruwa, murya da sauransu.
2. Shin ina buƙatar fahimtar ka'idar Bluetooth yayin amfani da tsarin tashar tashar jiragen ruwa?
A'a, kawai yi amfani da tsarin tashar tashar tashar Bluetooth azaman madaidaicin siriyal na zahiri. Bayan haɗawa tare da tsarin tashar tashar tashar Bluetooth akan kwamfuta ko wayar hannu, zaku iya buɗe madaidaicin tashar tashar jiragen ruwa ta Bluetooth da tsarin tashar tashar Bluetooth ta hanyar aikace-aikacen shirin sadarwa.
