Ziyanda izimo zokuxhuma amadivaysi e-Bluetooth amaningi ekuphileni kwansuku zonke. Ngezansi yisingeniso solwazi lokuxhumana okuningi kwereferensi yakho.
Uxhumano olulodwa lwe-Bluetooth oluvamile
Ukuxhumeka okukodwa kwe-Bluetooth, okubuye kwaziwe ngokuthi ukuxhuma kwe-point-to-point, kuyisimo esivame kakhulu soxhumano lwe-Bluetooth, njengamaselula<->i-Bluetooth yemoto. Njengezivumelwano eziningi zokuxhumana, ukuxhumana kwe-Bluetooth RF nakho kuhlukaniswe ngamathuluzi ayinhloko/esigqila, okuyi-Master/Slave (eyaziwa nangokuthi i-HCI Master/HCI Slave). Singawaqonda amadivaysi e-HCI Master ngokuthi "abahlinzeki bewashi le-RF", futhi ukuxhumana okungenantambo kwe-2.4G phakathi kwe-Master/Slave emoyeni kufanele kusekelwe Ewashini elinikezwe u-Master.
Indlela yokuxhumana eminingi ye-Bluetooth
Kunezindlela ezimbalwa zokufinyelela ukuxhumana okuningi kwe-Bluetooth, futhi okulandelayo yisingeniso ku-3.
1:Iphuzu-kuya-ku-Multi Point
Lesi simo sivamile uma kuqhathaniswa (njengemojula yephrinta ye-BT826), lapho imojuli ingaxhuma ngesikhathi esisodwa kufika kumafoni omakhalekhukhwini angu-7 (7 ACL links). Esimeni se-Point to Multi Point, idivayisi ye-Point (BT826) idinga ukushintsha ngokuqhubekayo isuke ku-HCI-Role iye ku-HCI-Master. Ngemva kokushintsha ngempumelelo, idivayisi yePhoyinti inikeza iwashi le-Baseband RF kwamanye amadivaysi e-Multi Point ukuqinisekisa ukuthi iwashi lihlukile. Uma ukushintsha kuhluleka, kungena kusimo se-Scatternet (isimo b esithombeni esilandelayo)
2: I-Scatternet (c esithombeni esingenhla)
Uma isimo soxhumano oluningi siyinkimbinkimbi, amanodi amaningi ayadingeka phakathi nendawo ukuze kudluliselwe. Kulawa ma-node odluliswayo, kufanele futhi asebenze njenge-HCI Master/Slave (njengoba kukhonjisiwe endaweni ebomvu kumfanekiso ongenhla).
Esimeni se-Scatternet, ngenxa yokuba khona kwama-HCI Master amaningi, kungase kube nabahlinzeki bewashi le-RF abaningi, okuholela ekuxhumekeni kwenethiwekhi okungazinzile kanye nekhono elibi lokulwa nokuphazamiseka.
Qaphela: Ezimweni ezisebenzayo zohlelo lokusebenza, ukuba khona kwe-Scatternet kufanele kugwenywe kakhulu ngangokunokwenzeka
I-BLE MESH
I-BLE Mesh njengamanje iyisixazululo esisetshenziswa kakhulu ekuxhumekeni kwe-Bluetooth (njengasensimini yamakhaya ahlakaniphile)
Inethiwekhi ye-mesh ingafinyelela ukuxhumana okuhlobene phakathi kwama-node amaningi, okuyindlela yokuxhumana esabalalisiwe enokuqukethwe okuningi okuqondile okungabuzwa ngakho ngqo.
3: Izincomo zokuxhuma okuningi
Sincoma imojuli yamandla aphansi (BLE) 5.2 esekela amamojula e-Bluetooth Ekilasi Lokuqala. I-FSC-BT1C isebenzisa i-chipset ye-Silicon Labs EFR671BG32, okuhlanganisa ne-microcontroller engu-21-bit 32 MHz ARM Cortex-M80 enganikeza amandla amakhulu okukhipha angu-33dBm. Ingasetshenziselwa izinhlelo zokusebenza zokuxhumana ze-Bluetooth Mesh futhi isetshenziswa kakhulu emikhakheni efana nokulawula ukukhanyisa kanye nezinhlelo zasekhaya ezihlakaniphile.
imikhiqizo Letihlobene
I-FSC-BT671C izici:
- Amandla okuphansi I-Bluetooth (BLE) 5.2
- Isitaki sephrothokholi ye-Bluetooth ye-MCU ehlanganisiwe
- Ikilasi 1 (amandla esiginali afika ku+10dBm)
- Inethiwekhi ye-Bluetooth BLE mesh
- Izinga le-UART baud elizenzakalelayo ngu-115.2Kbps, elingasekela u-1200bps ukuya ku-230.4Kbps
- I-UART, I2C, SPI, 12 bit ADC (1Msps) isixhumi esibonakalayo sokuxhuma idatha
- Usayizi omncane: 10mm * 11.9mm * 1.8mm
- Nikeza i-firmware eyenziwe ngokwezifiso
- Isekela izibuyekezo ze-firmware emoyeni (OTA).
- Izinga lokushisa lokusebenza: -40 ° C~105 ° C
Isifinyezo
Bluetooth ukuxhumana okuningi kusheshise ijubane lokulula empilweni. Ngikholwa ukuthi kuzoba nezinhlelo zokusebenza eziningi zokuxhuma kwe-Bluetooth empilweni. Uma udinga ukufunda okwengeziwe, ungaxhumana nethimba le-Feasycom!
