No ke aha ʻaʻole hiki ke loaʻa i ka module Bluetooth maʻamau ka hoʻohana ʻana i ka mana haʻahaʻa?
ʻO ka puka ʻana mai o ka module bluetooth haʻahaʻa haʻahaʻa ua hoʻomaikaʻi i nā hemahema o nā modules bluetooth maʻamau a ua lilo i hoʻonohonoho maʻamau no nā smartphones kiʻekiʻe. BLE module + smart home, e hoʻonui i ko mākou ola.
No ke aha e hiki ʻole ai i ka module Bluetooth maʻamau ke hoʻohana haʻahaʻa?
E nānā kākou i nā hiʻohiʻona o Bluetooth low energy module me ka Bluetooth module manufacturer Joinet:
1: ʻO ka mana haʻahaʻa haʻahaʻa
No ka hoʻemi ʻana i ka mana, hoʻohana nā mea uila haʻahaʻa Bluetooth i ka hapa nui o ko lākou manawa ma ke ʻano hiamoe. Ke hana ʻia ka hana, ala ʻokoʻa ka hāmeʻa a hoʻouna i kahi leka i ka ʻīpuka, kelepona a i ʻole PC. ʻAʻole ʻoi aku ka nui o ka mana kiʻekiʻe/peak ma mua o 15mA. Hoʻemi ʻia ka hoʻohana ʻana i ka mana ma ka hoʻohana ʻana i hoʻokahi hapaʻumi o nā mea hana Bluetooth kuʻuna. I ka palapala noi, hiki i ke pihi pihi ke mālama i ka hana paʻa no kekahi mau makahiki.
2: Paʻa, Palekana a me ka hilinaʻi
Ke hoʻohana nei ka ʻenehana Bluetooth Low Energy i ka ʻenehana Adaptive Frequency Hopping (AFH) e like me ka ʻenehana Bluetooth maʻamau, no laila e hōʻoiaʻiʻo ana i nā modules Bluetooth Low Energy hiki ke mālama i nā hoʻouna paʻa i nā kaiapuni RF "noisy" i nā noi hale, ʻoihana a me nā lāʻau lapaʻau. No ka ho'ēmiʻana i ke kumukūʻai a me ka hoʻohanaʻana i ka mana o ka hoʻohanaʻana i ka AFH, ua ho'ēmi kaʻenehana Bluetooth Low Energy i ka helu o nā kaha mai 79 1 MHz ākea ākea o kaʻenehana Bluetooth maʻamau i 40 2 MHz ākea ākea.
3: Ka noho like ʻole ʻole
Hoʻohana ka ʻenehana Bluetooth i ka 2.4GHz ISM frequency band ʻaʻole koi ʻia kahi laikini. Me ka nui o nā ʻenehana e kaʻana like ana i kēia lewa ea, pilikia ka hana ʻole i ka hoʻoponopono hewa ʻana a me ka hoʻouna hou ʻana ma muli o ke keakea (e laʻa me ka hoʻonui ʻana i ka latency, hoʻemi ʻia ka hana, etc.). I nā noi koi, hiki ke hoʻemi ʻia ka hoʻopilikia ma o ka hoʻolālā pinepine a me ka hoʻolālā antenna kūikawā. Ma muli o ka hoʻohana ʻana o ka module Bluetooth kuʻuna a me ka module haʻahaʻa haʻahaʻa Bluetooth i ka AFH, kahi ʻenehana hiki ke hōʻemi i ka hoʻopili ʻana o nā ʻenehana lekiō ʻē aʻe, ʻoi aku ka paʻa a me ka hilinaʻi o ka hoʻouna Bluetooth.
4: Laulā pili
He ʻokoʻa iki ka hoʻololi ʻana o ka ʻenehana Bluetooth haʻahaʻa haʻahaʻa mai ka ʻenehana Bluetooth kuʻuna. Hiki i kēia hoʻololi ʻokoʻa ke hoʻopili i kahi laina pili a hiki i 300 mika ma kahi chipset uea o 10 dBm (Bluetooth Low Energy maximum power).
5: Maʻalahi o ka hoʻohana a me ka hoʻohui
Hoʻokumu pinepine ʻia kahi piconet haʻahaʻa haʻahaʻa Bluetooth ma luna o kahi mea haku i hoʻopili ʻia i nā mea kauā he nui. I loko o kahi piconet, he haku a he kauā paha nā mea hana a pau, akā ʻaʻole hiki ke lilo i haku a me nā kauā i ka manawa like. Hoʻoponopono ka mea haku i ka alapine kamaʻilio o ka mea kauā, a hiki i ka mea kauā ke kamaʻilio e like me nā koi o ka mea haku. Hoʻohālikelike ʻia me ka ʻenehana Bluetooth kuʻuna, kahi hana hou i hoʻohui ʻia e ka ʻenehana haʻahaʻa haʻahaʻa Bluetooth ʻo ia ka hana "broadcast". Me kēia hiʻohiʻona, hiki i kahi mea kauā ke hōʻailona e pono e hoʻouna i ka ʻikepili i ka mea haku.
No ka mea ʻokoʻa ka hoʻololi ʻana o ka papa kino a me nā ʻano demodulation o Bluetooth maʻamau a me ka Bluetooth haʻahaʻa haʻahaʻa, ʻaʻole hiki ke kamaʻilio pū kekahi me nā hāmeʻa Bluetooth haʻahaʻa haʻahaʻa. Inā he haʻahaʻa ka mana Bluetooth ka mea haku, pono e lilo ka mea kauā i mea haʻahaʻa haʻahaʻa Bluetooth; like, a Classic Bluetooth kauā mea hiki wale kamaʻilio me ka Classic Bluetooth haku mea.
ʻO Joinet, ma ke ʻano he noiʻi a me ka hoʻomohala ʻana a me ka mea hana i nā modula Bluetooth haʻahaʻa haʻahaʻa, ma kahi o nā modula Bluetooth haʻahaʻa haʻahaʻa, loaʻa iā mākou nā hopena kūpono, e like me: nā pulupulu niho akamai, nā mea hoʻomaʻemaʻe wai pūnaewele, etc. Welina mai e kūkākūkā!
