Maitiro ekubatanidza Bluetooth Module

Kune mabhiriyoni eIoT (Internet yezvinhu) yekubatanidza munyika. Kune tambo dzakawanda chete dzinogona kuvigwa mumigero yepasi pevhu kana kupfuura pamusoro. Kana tambo dzakamonereka dzikasatanga kusvika kwatiri, mutengo, hupfumi, uye kugadzirisa kwese kunogona kutishayisa mweya. Nekuda kweBluetooth tekinoroji uye Bluetooth modules , midziyo inogona kubatanidza uye kuchinjana-yekutaurirana data zvachose pasina waya uchishandisa maredhiyo.

Chii chinonzi Bluetooth module?

Iyo Bluetooth module tekinoroji inoshanda senge interface, ichibatsira chero midziyo miviri kumisikidza isina waya yakaderera-simba Bluetooth yekubatanidza uye kumisikidza protocol yekutaurirana data pakati pemidziyo. Joinet's Bluetooth Low Energy modules akagadzirirwa akaderera-simba maturusi senge sensors, fitness trackers uye zvimwe zveIoT zvishandiso zvinoda kushoma mashandisirwo emagetsi uye hupenyu hurefu hwebhatiri. MaBluetooth modules ane akawanda maapplication uye anogona kushandiswa nenzira dzakasiyana siyana uye maapplication. Iwo anogona kushandiswa semwenje switch controller sezvo achigona kubatanidzwa kune microcontroller kuvheneka kana kudzima mwenje. Vanogonawo kuva nemamwe mashandisirwo nemashandisirwo.

Maitiro ekugadzirisa iyo Bluetooth module?

Kugadzirisa Bluetooth module kunosanganisira kuseta akasiyana ma paramita uye sarudzo kuti iite kuti ishande zvinoenderana nezvaunoda chaizvo. Iwo chaiwo matanho nemirairo anogona kusiyana zvichienderana nemodule uye chikuva chauri kushandisa. Aya anotevera matanho akajairwa ekugadzirisa Bluetooth module:

1. Magetsi

Ita shuwa kuti module yako yeBluetooth inofambiswa nemazvo. Mazhinji maBluetooth modules anoda yakagadzikana magetsi mukati meyawo yakatarwa voltage renji. Tarisa kune iyo module data sheet kana bhuku remagetsi chaiwo uye zvazvino zvinodiwa.

2. Bano

Batanidza iyo module yeBluetooth kune yako microcontroller kana komputa uchishandisa yakakodzera hardware interface (UART, SPI, I2C, nezvimwewo). Ita shuwa kuti kubatanidza kwakachengeteka uye module yakagara zvakanaka.

3. Firmware

Mamwe mamodule eBluetooth anogona kuuya ane preloaded firmware, nepo mamwe angangoda kuti uvheneke firmware paari. Kana zvichidikanwa, tevera mirairo yemugadziri weBluetooth module yekuisa firmware.

4.AT kuraira

Mazhinji maBluetooth modules anotsigira kushandiswa kwemirairo yeAT kugadzirisa marongero akadai sezita remudziyo, pairing mode, uye PIN kodhi. Tumira AT mirairo kune module kuseta aya ma paramita zvinoenderana nezvaunoda. Kuti uwane rondedzero yeAT mirairo iripo, ona iyo module dhatabheti kana bhuku rekushandisa.

5. Pairing

Kana iwe uchida kuti Bluetooth module yako itaurirane nemamwe madivayiri, akadai sema smartphones kana mamwe maBluetooth module, unofanirwa kuabatanidza. Pairing kazhinji inosanganisira kuseta PIN uye kuisa iyo module mune inowanikwa modhi. Kuti uite izvi, unogona kushandisa AT mirairo kana nzira dzepurogiramu.

6. Kuongorora

Mushure mekugadzirisa Bluetooth module, unogona kuyedza kugadzirisa kwako nekubatanidza iyo module yeBluetooth ne smartphone kana imwe mudziyo weBluetooth uye kutumira / kugamuchira data sezvinodiwa.

7. Kuvandudza application

Zvichienderana neprojekti yako, ungangoda kugadzira application kana chirongwa chekudyidzana neBluetooth module. Chishandiso chinogona kumhanya pane microcontroller, PC kana smartphone, uye inotaurirana nemodule ichishandisa yakakodzera Bluetooth mbiri (semuenzaniso. SPP, BLE GATT, nezvimwewo).

8. Chengetedzo

Kana iwe uine hanya nezve chengetedzo, ungangoda kumisikidza encryption uye echokwadi marongero paBluetooth module kuchengetedza data panguva yekutaurirana.

9. Zvinyorwa

Iva nechokwadi chekutarisa kune chaiyo Bluetooth module mugadziri zvinyorwa uye dhetabheti. Iwo chaiwo ekugadzirisa matanho uye anotsigirwa maficha anogona kusiyanisa zvakanyanya pakati peakasiyana mamodule uye vagadziri.

Ramba uchifunga kuti iwo chaiwo matanho nemirairo zvinogona kusiyana zvichienderana neBluetooth module uye chikuva chauri kushandisa. Iva nechokwadi chekutarisa kune dhatabheti remodule kana bhuku remushandisi kune yakadzama mirairo uye zvakatemwa.

Nzira yekuwedzera sei huwandu hweBluetooth module?

Kuwedzera huwandu hweBluetooth module kunogona kunetsa nekuti Bluetooth yakagadzirirwa kushanda mukati meiyo yakatarwa kuti iite zvakakwana. Nekudaro, iwe unogona kushandisa mamwe maitiro ekuwedzera huwandu mukati mezvipimo zveBluetooth tekinoroji.

1. Sarudza iyo chaiyo vhezheni yeBluetooth

Tekinoroji yeBluetooth yakashanduka nekufamba kwemakore, neimwe vhezheni itsva inopa yakagadziridzwa huwandu uye kuita. Kana zvichibvira, sarudza Bluetooth module inotsigira yazvino vhezheni yeBluetooth, sezvo inogona kunge iine zvirinani kugona.

2. Gadzirisa simba rekutumira

Mamwe mamodule eBluetooth anobvumidza iwe kugadzirisa simba rekutumira. Kuwedzera simba rekufambisa kunowedzera huwandu, asi kunogona zvakare kushandisa simba rakawanda. Ndapota chenjerera kuti usapfuure miganhu yepamutemo yechiremera munharaunda yako.

3. Shandisa antenna yekunze

Mazhinji maBluetooth modules ane akavakirwa-mukati chip antennas. Nekudaro, iwe unogona kazhinji kuwedzera kufukidzwa nekushandisa ekunze antenna. Ita shuwa kuti module yaunosarudza inotsigira ekunze antenna uye sarudza antenna yakakodzera yekushandisa kwako.

4. Shandisa antenna kuiswa

Ita shuwa kuti antenna iri munzvimbo yakanakisa yekuparadzira chiratidzo. Kazhinji, kuisa antenna munzvimbo yakachena, isina kuvharwa kure nezvinhu zvakakura zvesimbi kana madziro zvichabatsira kuvandudza kuvharika.

5. Deredza zvinotsausa

Bluetooth inoshanda mu2.4 GHz ISM (Industrial, Scientific, and Medical) bhendi, iyo inogoverwa nemimwe midziyo isina waya yakaita seWi-Fi nemicrowave oveni. Deredza kupindira nekusarudza nzira dzisina kuwandisa. Funga kushandisa frequency hopping spread spectrum (FHSS) kubatsira kudzikisira kukanganisa.

6. Wedzera mutsara wekuona

Masaini eBluetooth anogona kukanganiswa nezvipingamupinyi zvakaita semadziro uye zvinhu zvesimbi. Kuti uwedzere huwandu, ita shuwa kuti pane mutsara wakajeka wekuona pakati pekutumira uye kugamuchira zvishandiso. Kuderedza kuwanda kwezvipingamupinyi kunogona kuvandudza zvakanyanya huwandu.

7. Shandisa mesh network

MuBluetooth Low Energy (BLE) zvikumbiro, funga kushandisa mesh network. BLE mesh network inogona kutumira mameseji kuburikidza neakawanda node, zvinobudirira kuwedzera huwandu.

8. Bluetooth range extender

Bluetooth renji inotambanudza kana inodzokorora inogona kuwedzerwa kune yako setup kuti uwedzere kufukidzwa. Zvishandiso izvi zvinogashira masaini eBluetooth kubva kumodule yako uye wozvitumirazve, zvichiwedzera kuwedzera huwandu. Ita shuwa yekusarudza range extender inoenderana neyako vhezheni yeBluetooth.

9. Firmware uye protocol optimization

Ita shuwa kuti yako Bluetooth module iri kushandisa ichangoburwa firmware uye protocol shanduro, sezvo izvi zvingasanganisira renji uye simba rekugadzirisa.

10. Funga nezvemamwe matekinoroji

Kana uchida hurefu hurefu kupfuura hunogona kupihwa neBluetooth, funga mamwe mawaya tekinoroji akadai seZigbee, LoRa, kana cellular communications, akagadzirirwa maapplication akareba.

Nepo aya mazano achigona kubatsira kukwirisa huwandu hweBluetooth module, kune miganhu inoshanda kune Bluetooth huwandu nekuda kweiyo inoshanda frequency uye kushomeka kwesimba. Mune zvimwe zviitiko, ungangoda kusanganisa akawanda matekinoroji kuti uwane huwandu hunodiwa kune chaiyo application.
