Ubuchwepheshe be-Bluetooth Low Energy

Iyini i-Bluetooth Low Energy

I-Bluetooth LE, igama eligcwele ngu I-Bluetooth Low Energy, i-BLE, ubuchwepheshe benethiwekhi yendawo yomuntu siqu engenantambo obuklanywe futhi bamakethwa yi-Bluetooth SIG okuhloswe ngayo izinhlelo zokusebenza ezinoveli ekunakekelweni kwezempilo, ukuqina, amabhakhoni, ukuphepha, nezimboni zokuzijabulisa zasekhaya, njll. Ayizimele ku-Bluetooth BR/EDR futhi ayinakho. ukuhambisana, kodwa i-BR/EDR ne-LE zingahlala ndawonye.

Kuze kube manje i-BLE ithuthukise i-BLE 5.2, BLE 5.1, BLE 5.0, BLE 4.2, BLE 4.0 Bluetooth LE inguqulo, uma kuqhathaniswa ne-Classic Bluetooth, i-Bluetooth Low Energy ihloselwe ukunikeza ukusetshenziswa kwamandla okuncishiswe kakhulu kanye nezindleko ngenkathi kugcinwa ukuxhumana okufanayo, idatha. Izinga ngokuvamile liphansi kune-Classic Bluetooth, idivayisi ye-iOS isekela kuphela i-Bluetooth LE ekudluliseni idatha ngokuzenzakalelayo, futhi ngokuvamile, izinga ledatha licishe libe ngu-4KB/s we-BLE, kodwa inkampani ye-Feasycom inemojula ye-Bluetooth isekela izinga ledatha le-BLE elifika ku-75KB/s. . Isivinini sishesha izikhathi eziningi kune-BLE evamile.

Amamojula emodi ekabili ye-FSC-BT836B ne-FSC-BT826B Bluetooth 5.0 atuswa kakhulu ezinhlelweni ezidinga izinga eliphezulu ledatha, lezi zinhlobo ezimbili zisekela ngesikhathi esisodwa i-Classic Bluetooth ne-Bluetooth LE.

I-Bluetooth LE ngokuyinhloko ihlanganisa amaphrothokholi amabili: i-GATT ne-SIG Mesh. Ngephrofayili ye-GATT, ihlukaniswe yaba yi-GATT emaphakathi ne-peripheral (eyaziwa nangokuthi iklayenti le-GATT neseva).

I-Bluetooth LE inamaphrofayili athile ezisekeli zezemidlalo nezokuqina zihlanganisa:

• I-BCS (Isevisi Yokwakheka Komzimba)
• I-CSCP (Isivinini Sokuhamba Ngebhayisikili kanye Nephrofayili Ye-Cadence) yezinzwa ezixhunywe ebhayisikilini noma ebhayisikilini lokuzivivinya ukuze kulinganiswe isivinini nesivinini sesondo.
• I-CPP (Iphrofayela Yamandla Ebhayisikili)
• I-HRP (Iphrofayili Yezinga Lenhliziyo) yamadivayisi akala ukushaya kwenhliziyo
• I-LNP (Indawo kanye Nephrofayela Yokuzulazula)
• I-RSCP (Isivinini Sokugijima kanye Nephrofayili ye-Cadence)
• I-WSP (Iphrofayela Yesikali Sesisindo)

Amanye amaphrofayili:

• IPSP (Iphrofayili Yokusekela Iphrothokholi Ye-inthanethi)
• I-ESP (Iphrofayela Yokuzwa Kwemvelo)
• I-UDS (Isevisi Yedatha Yomsebenzisi)
• I-HOGP (HID phezu kwephrofayela ye-GATT) ivumela amagundane angenantambo anikwe amandla yi-Bluetooth LE, amakhibhodi namanye amadivayisi anikeza ukuphila kwebhethri okuhlala isikhathi eside.
