Pali zochitika zambiri zolumikizira zida zingapo za Bluetooth m'moyo watsiku ndi tsiku. M'munsimu muli mawu oyamba a chidziwitso cha maulaliki angapo kuti muwerenge.
Kulumikizana kwa Bluetooth kamodzi kokha
Bluetooth single connection, yomwe imadziwikanso kuti point-to-point connection, ndiyo njira yodziwika kwambiri yolumikizira Bluetooth, monga mafoni a m'manja<->galimoto pa bolodi la Bluetooth. Monga njira zambiri zoyankhulirana, kulumikizana kwa Bluetooth RF kumagawidwanso m'zida za master/akapolo, zomwe ndi Master/Slave (omwe amadziwikanso kuti HCI Master/HCI Slave). Titha kumvetsetsa zida za HCI Master monga "RF Clock providers", ndipo kulumikizana kwa 2.4G opanda zingwe pakati pa Master / Kapolo mlengalenga kuyenera kukhazikitsidwa pa Clock yoperekedwa ndi Master.
Njira yolumikizira ma Bluetooth ambiri
Pali njira zingapo zopezera ma Bluetooth ambiri, ndipo zotsatirazi ndi zoyambira 3.
1:Point-to-Multi Point
Nkhaniyi ndi wamba (monga chosindikizira BT826 gawo), kumene gawo akhoza kugwirizana 7 mafoni (7 ACL maulalo). Muzochitika za Point to Multi Point, chipangizo cha Point (BT826) chiyenera kusintha kuchokera ku HCI-Role kupita ku HCI-Master. Pambuyo posintha bwino, chipangizo cha Point chimapereka wotchi ya Baseband RF ku zipangizo zina za Multi Point kuti wotchiyo ikhale yapadera. Kusintha kukakanika, kumalowa muzochitika za Scatternet (zochitika b pachithunzi chotsatira)
2: Scatternet (c pachithunzi pamwambapa)
Ngati mawonekedwe olumikizirana ambiri ndi ovuta, ma node angapo amafunikira pakati kuti atumize. Kwa ma relay node awa, akuyeneranso kugwira ntchito ngati HCI Master/Slave (monga momwe zasonyezedwera mu node yofiira pachithunzi pamwambapa).
Muzochitika za Scatternet, chifukwa cha kukhalapo kwa HCI Masters angapo, pakhoza kukhala opereka mawotchi angapo a RF, zomwe zimapangitsa kuti ma intaneti asasunthike komanso kuti asasokonezedwe.
Zindikirani: Muzochitika zogwiritsira ntchito, kupezeka kwa Scatternet kuyenera kupewedwa momwe mungathere
BLE MESH
BLE Mesh ndiye yankho lomwe limagwiritsidwa ntchito kwambiri pamanetiweki a Bluetooth (monga m'nyumba zanzeru)
Ma mesh networking amatha kulumikizana ndi kulumikizana pakati pa ma node angapo, yomwe ndi njira yolumikizirana yogawidwa yokhala ndi zambiri zomwe zitha kufunsidwa mwachindunji.
3: Malingaliro amitundu yambiri
Tikupangira gawo la mphamvu yotsika (BLE) 5.2 yomwe imathandizira ma module a Class 1 Bluetooth. FSC-BT671C imagwiritsa ntchito chipangizo cha Silicon Labs EFR32BG21, kuphatikizapo 32-bit 80 MHz ARM Cortex-M33 microcontroller yomwe ingapereke mphamvu yochuluka kwambiri ya 10dBm. Itha kugwiritsidwa ntchito pa maukonde a Bluetooth Mesh ndipo imagwiritsidwa ntchito kwambiri m'magawo monga kuwongolera kuyatsa ndi machitidwe anzeru akunyumba.
malonda ofananira
Zithunzi za FSC-BT671C
- Low Mphamvu Bluetooth (BLE) 5.2
- Integrated MCU Bluetooth protocol stack
- Kalasi 1 (siginecha mphamvu mpaka+10dBm)
- Bluetooth BLE maukonde maukonde
- Mlingo wokhazikika wa UART baud ndi 115.2Kbps, womwe ungathe kuthandizira 1200bps mpaka 230.4Kbps
- UART, I2C, SPI, 12 bit ADC (1Msps) data yolumikizira mawonekedwe
- Kukula kochepa: 10mm * 11.9mm * 1.8mm
- Perekani firmware makonda
- Imathandizira pamlengalenga (OTA) zosintha za firmware
- Kutentha kwa ntchito: -40 ° C ~ 105 ° C
Chidule
Bluetooth kugwirizana kwachulukidwe kwathandizira mayendedwe osavuta m'moyo. Ndikukhulupirira kuti pakhala pali mapulogalamu ambiri olumikizirana ndi Bluetooth m'moyo. Ngati mukufuna kudziwa zambiri, mutha kulumikizana ndi gulu la Feasycom!
