Waxaa jira kiisas badan oo badan oo ku saabsan isku xirka aaladaha Bluetooth ee badan nolol maalmeedka. Hoos waxaa ku yaal horudhac aqoonta isku xirnaanta badan ee tixraacaaga.
Isku xirka hal Bluetooth ee caadiga ah
Xidhiidhka hal Bluetooth-ka ah, oo sidoo kale loo yaqaano isku xidhka bar-ilaa-dhibcaha, ayaa ah midka ugu badan ee ku xidhidhiyaha Bluetooth-ka, sida mobaylada<->baabuur ku xidhan Bluetooth. Sida hab-maamuuska isgaarsiinta intooda badan, isgaarsiinta RF Bluetooth waxay sidoo kale u qaybsantaa aaladaha sayid/adoonsiga, kuwaas oo kala ah Master/Adoon (sidoo kale loo yaqaan HCI Master/HCI Slave). Waxaan u fahmi karnaa aaladaha HCI Master inay yihiin "bixiyayaasha RF Clocks", iyo xidhiidhka wireless 2.4G ee u dhexeeya Master/Adoomaha hawada waa in lagu saleeyaa saacada uu bixiyo Master.
Habka isku xirka badan ee Bluetooth
Waxaa jira dhowr siyaabood oo lagu gaari karo isku xirka Bluetooth-ka badan, kan soo socdaa waa hordhac 3.
1:Bar-ilaa-Qodob Badan
Dhacdadani waa mid caadi ah (sida moduleka daabacaha BT826), halkaas oo module-ku uu isku mar ku xidhi karo ilaa 7 taleefannada gacanta (7 ACL links). Muuqaalka Point to Multi Point, aaladda Point (BT826) waxay u baahan tahay inay si firfircoon uga beddesho HCI-Door una gudubto HCI-Master. Ka dib markii si guul leh loo beddelo, aaladda Point waxay ku siinaysaa saacadda Baseband RF aaladaha kale ee Multi Point si loo hubiyo in saacaddu ay tahay mid gaar ah. Haddii beddelku guuldareysto, waxay gashaa Scatternet scenario (scenario b ee shaxanka soo socda)
2: Scatternet (c ee shaxanka sare)
Haddii xaaladda isku xidhka badan ay tahay mid aad u adag, noodhyo badan ayaa loo baahan yahay dhexda si loo gudbiyo. Nodes-ka gudbinta ah, waa inay sidoo kale u adeegaan HCI Master/Adoon (sida ku cad noodhka cas ee shaxanka sare).
Xaaladda Scatternet, iyadoo ay ugu wacan tahay joogitaanka HCI Masters badan, waxaa laga yaabaa inay jiraan bixiyeyaasha saacadaha RF ee badan, taasoo keentay isku xirnaanta shabakad aan degganeyn iyo awoodda ka hortagga faragelinta liidata.
Fiiro gaar ah: Xaaladaha codsiga dhabta ah, jiritaanka Scatternet waa in laga fogaadaa intii suurtagal ah
BLE MESH
BLE Mesh hadda waa xalka loogu isticmaalka badan yahay isku xirka Bluetooth (sida dhanka guryaha smart)
Isku xirka mesh wuxuu gaari karaa isgaarsiin laxiriirta oo udhaxeysa noodes badan, kaas oo ah qaab iskuxiran oo la qeybiyay oo leh waxyaabo badan oo gaar ah oo si toos ah wax looga weydiin karo.
3: Talada isku xidhka badan
Waxaan kugula talineynaa moduleka 5.2 awood hooseeya (BLE) kaas oo taageera Class 1 modules Bluetooth. FSC-BT671C waxay isticmaashaa Silicon Labs EFR32BG21 chipset, oo ay ku jiraan 32-bit 80 MHz ARM Cortex-M33 microcontroller kaas oo bixin kara wax soo saarka ugu sarreeya ee 10dBm. Waxaa loo isticmaali karaa codsiyada isku xirka Mesh Bluetooth waxaana si weyn loogu isticmaalaa meelaha sida kantaroolka nalka iyo nidaamyada guriga smart.
waxyaabaha la xiriira
FSC-BT671C Astaamaha:
- Power Low Bluetooth (BLE) 5.2
- Xirmada borotokoolka Bluetooth ee MCU ee isku dhafan
- Heerka 1 (awoodda calaamadaha ilaa +10dBm)
- Isku xirka mesh Bluetooth BLE
- Heerka UART baud ee caadiga ah waa 115.2Kbps, kaas oo taageeri kara 1200bps ilaa 230.4Kbps
- UART, I2C, SPI, 12 bit ADC (1Msps) isku xirka xogta
- Cabbir yar: 10mm * 11.9mm * 1.8mm
- Bixi firmware habaysan
- Waxay taageertaa hawada sare (OTA) cusboonaysiinta firmware
- Heerkulka shaqada: -40 ° C ~ 105 ° C
Summary
Bluetooth isku xidhka badan ayaa deddejiyay xawliga ku habboonaanta nolosha. Waxaan aaminsanahay inay jiri doonaan codsiyo badan oo isku xirka Bluetooth ee nolosha. Haddii aad u baahan tahay inaad wax badan ka barato, waxaad la xiriiri kartaa kooxda Feasycom!
