Kune akawanda uye akawanda makesi ekubatanidza akawanda maBluetooth zvishandiso muhupenyu hwezuva nezuva. Pazasi pane sumo yeruzivo rwekubatanidzwa kwakawanda kwereferensi yako.
Yakajairika Bluetooth imwe chete yekubatanidza
Bluetooth single connection, inozivikanwawo sekuti-point-to-point connection, ndiyo inonyanya kufanana neBluetooth connection scenario, yakadai senharembozha <-> motokari pa-bhodhi Bluetooth. Kufanana nemaprotocol mazhinji ekutaurirana, Bluetooth RF kutaurirana yakakamurwa kuita tenzi / muranda zvishandiso, zvinoti Master/Slave (inozivikanwawo seHCI Master/HCI Slave). Tinogona kunzwisisa HCI Master zvishandiso se "RF Clock providers", uye 2.4G isina waya yekukurukurirana pakati paTenzi / Muranda mumhepo inofanira kubva paClock yakapiwa naTenzi.
Bluetooth nzira yekubatanidza yakawanda
Pane nzira dzinoverengeka dzekuwana Bluetooth yakawanda yekubatanidza, uye inotevera sumo ku3.
1:Point-to-Multi Point
Mamiriro ezvinhu aya akajairika (akadai semudhinda BT826 module), apo module inogona panguva imwe chete kubatanidza kusvika 7 nharembozha (7 ACL zvinongedzo). MuPoint to Multi Point scenario, iyo Point mudziyo (BT826) inoda kushingaira kushandura kubva kuHCI-Basa kuenda kuHCI-Master. Mushure mekubudirira kuchinjika, iyo Point mudziyo inopa Baseband RF wachi kune mamwe maMulti Point zvishandiso kuti ive nechokwadi chekuti wachi yakasarudzika. Kana iyo switching ikatadza, inopinda muScatternet scenario (chiitiko b mumufananidzo unotevera)
2: Scatternet (c pamufananidzo uri pamusoro)
Kana iyo yakawanda yekubatanidza mamiriro akaomesesa, akawanda nodes anodiwa pakati kuti adzoke. Kune aya marelay node, anofanirwawo kushanda seHCI Master/Muranda (sezvinoratidzwa mune dzvuku node mumufananidzo uri pamusoro).
Mune mamiriro eScatternet, nekuda kwekuvapo kweakawanda HCI Masters, panogona kunge paine akawanda maRF clock providers, zvichikonzera kusagadzikana kwetiweki yekubatanidza uye kushomeka kwekudzivirira-kukanganisa kugona.
Cherechedza: Muzviitiko zvekushandisa, kuvapo kweScatternet kunofanira kudzivirirwa zvakanyanya sezvinobvira
BLE MESH
BLE Mesh parizvino ndiyo inonyanya kushandiswa mhinduro muBluetooth networking (senge mumunda wedzimba dzakangwara)
Mesh networking inogona kuwana kutaurirana kwakabatana pakati peakawanda node, inova nzira yetiweki yakagoverwa ine akawanda chaiwo emukati anogona kubvunzwa zvakananga nezvayo.
3: Multi yekubatanidza kurudziro
Isu tinokurudzira yakaderera-simba (BLE) 5.2 module inotsigira Kirasi 1 Bluetooth module. Iyo FSC-BT671C inoshandisa Silicon Labs EFR32BG21 chipset, kusanganisira 32-bit 80 MHz ARM Cortex-M33 microcontroller iyo inogona kupa yakanyanya simba kubuda kwe10dBm. Inogona kushandiswa kuBluetooth Mesh networking application uye inoshandiswa zvakanyanya muminda senge mwenje wekudzora uye smart home systems.
