Bluetooth Low Energy tekinoroji

Chii chinonzi Bluetooth Low Energy

Bluetooth LE, zita rakazara ndere Makaralı Low Energy, colloquially BLE, iwireless personal area network tekinoroji yakagadzirwa uye inotengeswa neBluetooth SIG yakanangana nezvitsva zvekushandisa muhutano, kusimba, mabhekoni, chengetedzo, uye maindasitiri evaraidzo epamba, nezvimwe. Yakazvimiririra kubva kuBluetooth BR/EDR uye haina kugarisana, asi BR/EDR uye LE zvinogona kugarisana.

Kusvika parizvino BLE yakagadzira BLE 5.2, BLE 5.1, BLE 5.0, BLE 4.2, BLE 4.0 Bluetooth LE vhezheni, zvichienzaniswa neClassic Bluetooth, Bluetooth Low Energy inoitirwa kupa yakadzikisirwa simba rekushandisa uye mutengo uchichengetedza kutaurirana kwakafanana, iyo data. chiyero chinowanzo kuderera kupfuura Classic Bluetooth, iyo iOS mudziyo unongotsigira Bluetooth LE yekufambiswa kwedata nekukasira, uye kazhinji, chiyero che data chinenge 4KB/s yeBLE, asi Feasycom kambani ine Bluetooth module inotsigira BLE data rate kusvika 75KB/s. . Iko kumhanya kwakakurumidza kakawanda kupfuura yakajairwa BLE.

Iyo FSC-BT836B uye FSC-BT826B Bluetooth 5.0 dual mode modules inokurudzirwa zvakanyanya kune maapplication anoda data rakawanda, aya mamodheru maviri panguva imwe chete anotsigira Classic Bluetooth uye Bluetooth LE.

Bluetooth LE inonyanya kusanganisira maviri maprotocol: GATT uye SIG Mesh. Kune mbiri yeGATT, yakakamurwa kuita GATT yepakati nepakati (inozivikanwawo seGATT mutengi uye sevha).

Bluetooth LE ine mamwe maprofile emitambo uye kusimba zvinhu zvinosanganisira:

• BCS (Body Composition Service)
• CSCP (Cycling Speed ​​uye Cadence Profile) yemasensor akasungirirwa pabhasikoro kana bhasikoro rekurovedza muviri kuyera cadence uye kumhanya kwevhiri.
• CPP (Cycling Power Profile)
• HRP (Heart Rate Profile) yemidziyo inoyera kurova kwemoyo
• LNP (Nzvimbo uye Navigation Profile)
• RSCP (Kumhanya Kumhanya uye Cadence Mbiri)
• WSP (Weight Scale Profile)

Mamwe ma profiles:

• IPSP (Internet Protocol Support Profile)
• ESP (Environmental Sensing Profile)
• UDS (Mushandisi Data Service)
• HOGP (HID pamusoro peGATT Profile) inobvumira Bluetooth LE-inogonesa Wireless mbeva, kiyibhodhi uye zvimwe zvishandiso zvinopa kwenguva refu yebhatiri hupenyu.
