Kukho iimeko ezininzi zokuqhagamshela izixhobo ezininzi zeBluetooth kubomi bemihla ngemihla. Apha ngezantsi kukho intshayelelo yolwazi lonxibelelwano oluninzi lwereferensi yakho.
Uqhagamshelo olulodwa lweBluetooth oluqhelekileyo
Uqhagamshelo olulodwa lweBluetooth, olukwabizwa ngokuba yi-point-to-point connection, yeyona nto ixhaphakileyo yoqhagamshelo lweBluetooth, njengeemfonomfono<->imoto ekwibhodi yeBluetooth. Njengoninzi lweeprothokholi zonxibelelwano, unxibelelwano lweBluetooth RF lukwahlulwe ngokwezixhobo eziphambili/zekhoboka, ezizezi Master/Slave (ekwaziwa ngokuba yiHCI Master/HCI Slave). Sinokuqonda izixhobo ze-HCI Master njenge "RF Clock providers", kunye ne-2.4G unxibelelwano olungenazintambo phakathi kwe-Master / Slave emoyeni kufuneka lusekelwe kwiClock enikezwe nguMfundisi.
Uqhagamshelo oluninzi lweBluetooth
Kukho iindlela ezininzi zokufezekisa uqhagamshelo oluninzi lweBluetooth, kwaye oku kulandelayo sisingeniso kwi3.
1:Inqaku-ukuya-Inqaku eliMulti
Lo mzekelo uqhelekile (ofana nomshicileli we-BT826 imodyuli), apho imodyuli ingadibanisa ngaxeshanye ukuya kuthi ga kwiifowuni eziphathwayo ezisi-7 (7 ACL links). Kwimeko yePoint to Multi Point, isixhobo sePoint (BT826) kufuneka sitshintshe ngokusebenzayo ukusuka kwi-HCI-Indima ukuya kwi-HCI-Master. Emva kokutshintsha ngempumelelo, isixhobo sePoint sibonelela ngewotshi ye-Baseband RF kwezinye izixhobo zeMulti Point ukuqinisekisa ukuba iwotshi yodwa. Ukuba utshintsho aluphumeleli, lungena kwi-Scatternet scenario (imeko b kulomfanekiso ulandelayo)
2: I-Scatternet (c kulo mfanekiso ungasentla)
Ukuba imeko yoqhagamshelo oluninzi intsokothile, iindawo ezininzi ziyafuneka embindini ukugqithisela. Kwezi nodi zokuhanjiswa, kufuneka zisebenze njenge-HCI Master / Slave (njengoko kubonisiwe kwindawo ebomvu kulo mfanekiso ungasentla).
Kwimeko ye-Scatternet, ngenxa yobukho bee-HCI Masters ezininzi, kunokubakho ababoneleli bewotshi abaninzi be-RF, okukhokelela kunxibelelwano lwenethiwekhi olungazinzanga kunye nokukwazi ukuchasana nokuphazamiseka.
Qaphela: Kwiimeko ezisebenzayo, ubukho be-Scatternet kufuneka buphetshwe kangangoko kunokwenzeka
UBLE MESH
I-BLE Mesh okwangoku sesona sisombululo sisetyenziswa kakhulu kuthungelwano lweBluetooth (njengakwintsimi yamakhaya ahlakaniphileyo)
Uthungelwano lweMesh lunokufikelela kunxibelelwano olunxulumeneyo phakathi kweenodi ezininzi, eyindlela yothungelwano esasazwayo enezinto ezininzi ezinokuthi zibuzwe ngokuthe ngqo.
3: Ingcebiso yonxibelelwano oluninzi
Sincoma imodyuli ye-low-power (BLE) 5.2 exhasa iimodyuli ze-Bluetooth zeClass 1. I-FSC-BT671C isebenzisa i-chipset ye-Silicon Labs EFR32BG21, kubandakanywa ne-32-bit 80 MHz ARM Cortex-M33 microcontroller enokubonelela ngokuphuma kwamandla aphezulu kwi-10dBm. Ingasetyenziselwa iBluetooth Mesh networking applications kwaye isetyenziswa ngokubanzi kwimimandla efana nolawulo lokukhanyisa kunye neenkqubo zekhaya ezihlakaniphile.
izinto eziyeleleneyo
Iimpawu eziphambili zeFSC-BT671C:
- Amandla aphantsi IBluetooth (BLE) 5.2
- Iprotocol edityanisiweyo ye-MCU yeBluetooth
- Udidi loku-1 (umqondiso wamandla ukuya ku+10dBm)
- Uthungelwano lweBluetooth BLE mesh
- Izinga le-baud ye-UART engagqibekanga yi-115.2Kbps, enokuxhasa i-1200bps ukuya kwi-230.4Kbps
- UART, I2C, SPI, 12 bit ADC (1Msps) ujongano loqhagamshelwano lwedatha
- Ubungakanani obuncinci: 10mm * 11.9mm * 1.8mm
- Nikeza i-firmware eyenzelwe wena
- Ixhasa emoyeni (OTA) uhlaziyo lwe-firmware
- Ubushushu bokusebenza: -40 ° C~105 ° C
isishwankathelo
Bluetooth Unxibelelwano oluninzi luye lwakhawulezisa isantya sokwenza lula ebomini. Ndiyakholelwa ukuba kuya kubakho usetyenziso oluninzi lweBluetooth ebomini. Ukuba ufuna ukufunda ngakumbi, ungaqhagamshelana neqela leFeasycom!
