Hauv lub neej niaj hnub thiab kev tsim khoom, Bluetooth Tsawg Zog (BLE) yog lub tshuab muaj zog. Rau qhov tshiab BLE ntaus ntawv tsim, cov khoom lag luam engineers yuav xav tau qee qhov BLE modules uas tuaj yeem ua lub luag haujlwm hauv nruab nrab thiab sab hauv.
BLE Central yog dab tsi?
Lub Central yog ib lub cuab yeej, uas luam theej duab rau Bluetooth li txuas thiab siv cov ntaub ntawv tuav los ntawm lawv. Feem ntau, Central cov cuab yeej muaj txiaj ntsig zoo dua ntawm cov peev txheej xws li suav lub zog piv rau cov khoom siv Peripheral. Kev sib txuas ua ntej: thaum pib, lub cuab yeej hu ua Central ntaus ntawv, tom qab txuas nrog, nws hu ua tus tswv.
BLE Peripheral yog dab tsi?
BLE peripheral tuaj yeem luam tawm los ntawm Bluetooth Central ntaus ntawv. Tom qab kev sib txuas ntawm BLE tau tsim, lub cuab yeej txuas txuas hu ua qhev.
Tam sim no, Feasycom Bluetooth Tsawg Zog Module tuaj yeem txhawb nqa hom nruab nrab thiab peripheral. Thaum BLE module scans lwm yam khoom siv BLE, nws yog BLE hauv nruab nrab cov cuab yeej, thiab BLE module raug tshuaj xyuas los ntawm lwm cov khoom siv, nws yuav yog BLE peripheral ntaus ntawv. Txhawm rau ua tau raws li qhov xav tau ntawm daim ntawv thov sib txawv, Feasycom tau tsim ntau yam BLE modules, xws li cov kav hlau txais xov me Nordic nRF52832 module FSC-BT630, lub ultra-me me module FSC-BT690 thiab TI CC2640 module FSC-BT616. Yog xav paub ntxiv, txais tos hu rau Feasycom Team.
