Tekinoloje ya Bluetooth Low Energy

Kodi Bluetooth Low Energy ndi chiyani

Bluetooth LE, dzina lonse ndi Mphamvu Zochepa za Bluetooth, colloquially BLE, ndi ukadaulo wopanda zingwe wapaintaneti wopangidwa ndikugulitsidwa ndi Bluetooth SIG yoyang'ana mapulogalamu atsopano azaumoyo, kulimbitsa thupi, ma beacon, chitetezo, ndi zosangalatsa zapanyumba, ndi zina. Imadziyimira pawokha pa Bluetooth BR/EDR ndipo ilibe kuyanjana, koma BR/EDR ndi LE zitha kukhala limodzi.

Mpaka pano, BLE yapanga BLE 5.2, BLE 5.1, BLE 5.0, BLE 4.2, BLE 4.0 Bluetooth LE Baibulo, poyerekeza ndi Classic Bluetooth, Bluetooth Low Energy cholinga chake ndi kuchepetsa kwambiri kugwiritsa ntchito mphamvu ndi mtengo pamene kusunga kulankhulana chimodzimodzi, deta. Mtengo wocheperako kuposa Classic Bluetooth, chipangizo cha iOS chimangogwirizira Bluetooth LE potumiza deta mwachisawawa, ndipo nthawi zambiri, kuchuluka kwa data kumakhala pafupifupi 4KB/s kwa BLE, koma kampani ya Feasycom ili ndi gawo la Bluetooth lomwe limathandizira BLE data mpaka 75KB/s. . Kuthamanga kumathamanga nthawi zambiri kuposa BLE wamba.

Ma module a FSC-BT836B ndi FSC-BT826B Bluetooth 5.0 amitundu iwiri amalimbikitsidwa kwambiri pamapulogalamu omwe amafunikira kuchuluka kwa data, mitundu iwiriyi nthawi imodzi imathandizira Classic Bluetooth ndi Bluetooth LE.

Bluetooth LE imaphatikizanso ma protocol awiri: GATT ndi SIG Mesh. Kwa mbiri ya GATT, idagawidwa kukhala GATT chapakati ndi zotumphukira (zodziwikanso kuti GATT kasitomala ndi seva).

Bluetooth LE ili ndi mbiri yazamasewera ndi zolimbitsa thupi monga:

• BCS (Body Composition Service)
• CSCP (Liwiro Lothamanga ndi Cadence Profile) ya masensa omwe amamangiriridwa panjinga kapena panjinga yolimbitsa thupi kuti ayeze kuthamanga kwa magudumu.
• CPP (Mbiri ya Mphamvu Zapanjinga)
• HRP (Mtundu wa Kugunda kwamtima) pazida zomwe zimayezera kugunda kwa mtima
• LNP (Nkhani ya Malo ndi Navigation)
• RSCP (Kuthamanga Kwambiri ndi Mbiri ya Cadence)
• WSP (Kulemera Kwambiri Mbiri)

Mbiri zina:

• IPSP (Protocol Support Profile)
• ESP (mbiri Yowona Zachilengedwe)
• UDS (User Data Service)
• HOGP (HID over GATT Profile) yolola mbewa zopanda zingwe za Bluetooth LE, ma kiyibodi ndi zida zina zomwe zimapereka moyo wa batri wokhalitsa.

BLE mayankho:
