He ʻumi mau mea e noʻonoʻo ai i ke kūʻai ʻana i kahi module Bluetooth
ʻOiai i kēia manawa he nui nā modula Bluetooth o nā ʻano nui a me nā ʻano like ʻole ma ka mākeke e koho mai, nui nā mea hana akamai i pilikia i ke koho ʻana i kahi module Bluetooth kūpono no kā lākou huahana. ʻOiaʻiʻo, i ke kūʻai ʻana i kahi module Bluetooth , pili nui ia i ka huahana āu e hana ai a me ke ʻano i hoʻohana ʻia ai.
Ma lalo iho nei, hōʻuluʻulu ʻo Joinet i nā mea he ʻumi kiʻekiʻe e hoʻolohe ai i ke kūʻai ʻana i nā modula Bluetooth no ke kuhikuhi ʻana o ka hapa nui o nā mea hana ʻo IoT.
Nā mea e nānā i ke kūʻai ʻana i kahi module Bluetooth
1. Hiohao
Hoʻoholo ka chip i ka mana helu o ka module Bluetooth. Me ka ʻole o ka "core" ikaika, ʻaʻole hiki ke hōʻoia ʻia ka hana o ka module Bluetooth. Inā koho ʻoe i kahi module Bluetooth haʻahaʻa haʻahaʻa, ʻoi aku ka maikaʻi o nā chips ʻo Nordic, Ti, etc.
2. Gmeaʻai
Hoʻokaʻawale ʻia ʻo Bluetooth i ka Bluetooth kuʻuna a me ka Bluetooth-mana haʻahaʻa. ʻO nā mea akamai e hoʻohana ana i nā modula Bluetooth kuʻuna i ka wehe pinepine ʻana a koi i nā paʻi hou pinepine ʻana, a e pau koke ka pākaukau. Pono nā polokalamu akamai e hoʻohana ana i nā modula Bluetooth mana haʻahaʻa i hoʻokahi paʻa. Hiki ke holo ka pila pihi hoʻokahi no ka manawa lōʻihi. No laila, inā ʻoe e hoʻohana nei i kahi hāmeʻa uila uila uila, ʻoi aku ka maikaʻi o ka hoʻohana ʻana i kahi module Bluetooth haʻahaʻa Bluetooth 5.0/4.2/4.0 e hōʻoia i ka huahana.’s ola pākaukau.
3. Hoʻouna maʻiʻo
Hiki i ka module Bluetooth ke hoʻouna i ka ʻikepili a me ka ʻike leo. Hoʻokaʻawale ʻia ia i ka module data Bluetooth a me ka module leo Bluetooth e like me kāna hana. Hoʻohana nui ʻia ka module data Bluetooth no ka lawe ʻana i ka ʻikepili, a kūpono ia no ka ʻike a me ka lawe ʻana i ka ʻikepili ma nā wahi ākea me nā kaʻa kiʻekiʻe e like me nā hōʻikeʻike, nā kikowaena, nā halemai, nā ʻāpana, etc.; Hiki i ka module leo Bluetooth ke hoʻouna i ka ʻike leo a kūpono ia no ke kamaʻilio ʻana ma waena o nā kelepona paʻalima Bluetooth a me nā poʻo Bluetooth. Hoʻouna ʻike leo.
4. Laki hoʻouna
I ke koho ʻana i kahi module Bluetooth, pono ʻoe e maopopo e pili ana i ka hoʻohana ʻana i ka module Bluetooth, a e hoʻohana i ka helu hoʻouna ʻikepili i koi ʻia ma lalo o nā kūlana hana e like me ke koho koho. Ma hope o nā mea a pau, ʻokoʻa ka helu ʻikepili i koi ʻia no ka hoʻouna ʻana i nā mele kiʻekiʻe i nā headphones mai ka monitor beat monitor. 'Oko'a ka nui o ka 'ikepili i koi 'ia.
5. Ka mamao hoʻouna
Pono nā mea hana ʻo IoT e hoʻomaopopo i ke kaiapuni kahi i hoʻohana ʻia ai kā lākou huahana a inā he kiʻekiʻe ko lākou koi mamao mamao. No nā huahana uea ʻole e koi ana i ka mamao hoʻoili uila kiʻekiʻe, e like me nā ʻiole uila, nā headphone uila, a me nā mana mamao, hiki iā ʻoe ke koho i nā modula Bluetooth me kahi mamao hoʻouna ʻoi aku ma mua o 10 mika; no nā huahana ʻaʻole makemake i ka mamao o ka hoʻouna ʻana i nā kelepona kiʻekiʻe, e like me nā kukui RGB decorative, hiki iā ʻoe ke koho ʻO ka mamao o ka lawe ʻana ma mua o 50 mika.
6. ʻAno hoʻopili
ʻEkolu ʻano o nā modula Bluetooth: ʻano plug-in pololei, ʻano mauna i luna a me ka adapter port serial. ʻO ke ʻano hoʻopololei pololei he mau pine, kahi kūpono no ke kūʻai mua ʻana a kūpono no ka hana liʻiliʻi; Hoʻohana ka module i kau ʻia ma luna i nā pad semi-circular e like me nā pine, kahi kūpono no ka hana hoʻoheheʻe hou ʻana i ka nui no nā mea lawe liʻiliʻi; Hoʻohana ʻia ka adapter Bluetooth serial Inā hiki ʻole ke kūkulu ʻia ʻo Bluetooth i loko o ka hāmeʻa, hiki iā ʻoe ke hoʻopili pololei iā ia i loko o ka port serial nine-pin o ka hāmeʻa a hiki ke hoʻohana koke ʻia ma hope o ka hoʻā ʻana.
7. Ikepili
Ma muli o nā koi o ke kikowaena o nā hana kikoʻī i hoʻokō ʻia, ua māhele ʻia nā loulou o ka module Bluetooth i nā kikowaena serial, nā pilina USB, nā awa IO digital, nā awa IO analog, nā awa polokalamu SPI a me nā leo leo. Hiki i kēlā me kēia kikowaena ke hoʻokō i nā hana like ʻole. . Inā he hoʻoili ʻikepili wale nō, e hoʻohana wale i ke kikowaena serial (level TTL).
8. Pilikia haku-kauwa
Hiki i ka master module ke ʻimi ikaika a hoʻohui i nā modula Bluetooth ʻē aʻe me ka pae mana Bluetooth like a haʻahaʻa paha ma mua ona; Ke kali nei ka module kauā i nā poʻe ʻē aʻe e ʻimi a hoʻopili, a ʻo ka mana Bluetooth e like a i ʻole ka kiʻekiʻe ma mua o kāna ponoʻī. ʻO ka hapa nui o nā mea akamai ma ka mākeke e koho i nā modula kauā, aʻo nā modula master e hoʻohana maʻamau ʻia ma nā polokalamu e like me nā kelepona paʻa i hiki ke lilo i mau kikowaena mana.
9. Antenna
Loaʻa i nā huahana like ʻole nā koi no nā antenna. I kēia manawa, ʻo nā antennas maʻamau i hoʻohana ʻia no nā modula Bluetooth me nā antenna PCB, nā antenna ceramic a me nā antenna waho IPEX. Inā hoʻokomo ʻia lākou i loko o kahi pale metala, koho ʻia nā modula Bluetooth me nā antenna waho IPEX.
10. Kūʻai-pono
ʻO ke kumukūʻai ka hopohopo nui loa no nā mea hana lako IoT
Ua komo nui ʻo Joinet i ke kahua o nā modula Bluetooth haʻahaʻa haʻahaʻa no nā makahiki he nui. I ka makahiki 2008, ua lilo ʻo ia i mea hoʻolako punahele no nā hui 500 kiʻekiʻe o ka honua. Loaʻa iā ia kahi pōʻai pōkole pōkole a hiki ke pane koke i nā pono like ʻole o ka hapa nui o nā mea hana lako. Hiki i ke kaulahao lako o ka hui a me nā laina hana ke hoʻokō i nā pōmaikaʻi kumu kūʻai, e hōʻoia ana e hiki i ka hapa nui o nā mea hana lako ke hoʻohana i nā modula Bluetooth haʻahaʻa haʻahaʻa haʻahaʻa. Ma kahi o nā manaʻo he ʻumi i luna, pono e hoʻomaopopo nā mea hana i ka nui, ka loaʻa ʻana o ka sensitivity, ka mana hoʻouna, Flash, RAM, etc. o ka module Bluetooth i ke kuai ana i ka module Bluetooth.
