I-ARDUINO CC2541 Bluetooth V4.0 HM-11 BLE Incwadi Yomsebenzisi Yemojuli
Isingeniso
Lena imojula ye-SMD BLE esetshenziswa ku-BLE Bee yethu kanye ne-Xadow BLE. Isekelwe ku-TI cc2541 chip, yenza ama-node enethiwekhi aqinile ukuthi akhelwe ngezindleko eziphansi ze-bill-of-material ephansi futhi ifaneleka kakhulu izinhlelo zokusebenzisa amandla aphansi kakhulu. Imojuli incane futhi kulula ukuyisebenzisa, nge-firmware ehleliwe yomkhiqizi, ungakha ngokushesha ukuxhumana kwe-BLE ngomyalo wayo we-AT. Isekela ukuxhumana kwe-BLE nge-iphone, ipad ne-Android 4.3.

Imiyalo ye-AT & Ukucushwa
- Buza ikheli le-MAC lomdabu
Thumela: AT + ADDR?
Thumela ngemva kokubuyisela ngempumelelo: KULUNGILE + LADD: Ikheli le-MAC (ikheli leyunithi yezinhlamvu eziyi-12) - Buza inani le-baud
Thumela: AT+BAUD? Thumela ngemva kokubuyisela ngempumelelo: KULUNGILE + Thola: [iphara1] Ububanzi bepharamitha 1:0 ~ 8. Imingcele ehambisana nalokhu: 0 imele 9600, 1, 2, 9600, 38400, egameni lommeleli 57600, 115200, 5 , 4800, 6, 7 imele u-1200, 1200 2400. Izinga le-baud elizenzakalelayo libe ngu-9600. - Setha inani le-baud
Thumela: AT+BAUD[para1] Thumela ngemva kokubuyisela ngempumelelo: KULUNGILE+Setha:[iphara1] Example: thumela: AT + BAUD1, buyisela: KULUNGILE + Setha: 2.Isilinganiso se-baud sisethelwe ku-19200.
Qaphela: ngemva kokushintshela ku-1200, imojula ngeke isasekela ukumiswa komyalo we-AT, bese ucindezela i-PIO0 ngaphansi kokubekwe eceleni, imojula ingabuyisela Izilungiselelo zefekthri.Ungatusi ukusebenzisa isilinganiso se-baud.Ngemva kokusetha izinga le-baud, amamojula kufanele abe kugesi, amapharamitha amasha angase asebenze. - kusuka kudivayisi exhunywe ekhelini le-bluetooth elishiwo
Thumela: AT+CON[para1] Thumela ngemva kokubuyisela ngempumelelo: OK+CONN[iphara2] I-Para2 ububanzi ithi: A, E, F
Example: kusuka ekhelini le-bluetooth ngu: 0017EA0943AE, ukuthumela i-AT + CON0017EA0943AE, ukubuyisela imojula: KULUNGILE + CONNA noma KULUNGILE + + CONNF CONNE noma KULUNGILE. - ukususwa kwezinto ezihambisana nolwazi
Thumela: AT + CLEAR
Thumela ngemva kokubuyisela ngempumelelo: KULUNGILE +
SULA Impumelelo ecacile ibinolwazi lwekhodi yedivayisi exhunyiwe. - imodi yokusebenza yemojuli yombuzo
Thumela: AT + MODE?
Thumela ngemva kokubuyisela ngempumelelo: KULUNGILE + Thola: [i-para] Para: ububanzi obungu-0 ~ 2. U-0 umele imodi yokudlula, egameni lokuthola kwe-PIO + isilawuli kude + 1 ukudlula, 2 ukudlula okumele + imodi yesilawuli kude.Okuzenzakalelayo ngi 0. - setha imodi yokusebenza yemojuli:
Thumela: AT + MODE [] Thumela ngemva kokubuyisela ngempumelelo: KULUNGILE + Setha: [para] - buza igama ledivayisi
Thumela: AT + NAME?
Thumela ngemva kokubuyisela ngempumelelo: KULUNGILE + NAME [iphara1] - setha igama ledivayisi
Thumela: AT + NAME [para1] Thumela ngemva kokubuyisela ngempumelelo: KULUNGILE + Setha: [iphara1] Example: Setha igama ledivayisi ku-Seed, ithumela i-AT + NAMESeeed, buyisela okuthi KULUNGILE + Setha: Bona NGALESI sikhathi, igama lemojula ye-bluetooth selishintshiwe laba yi-Seed. Qaphela: ngemva kokubulawa komyalelo, okudingekayo kugesi, setha imingcele yokugunyazwa. - umbuzo ofanayo nephasiwedi
Thumela: AT + PASS?
Thumela ngemva kokubuyisela ngempumelelo: KULUNGILE + PASS: [iphara1] Ububanzi bePara1 bungu-000000 ~ 999999, okuzenzakalelayo ngu-000000. - ukumatanisa isethi iphasiwedi
Thumela i-AT + PASS [iphara1] Thumela ngemva kokubuyisela ngempumelelo: KULUNGILE + Setha: [para1] - buyisela Izilungiselelo zasembonini
Ukuthumela kwe-AT + RENEW
Thumela ngemva kokubuyisela ngempumelelo: KULUNGILE + BUSHA
Buyisela imojula yezilungiselelo zefekthri ezenzakalelayo, Izilungiselelo zemojula zizosethwa kabusha ngakho, emuva efekthri nesimo sokuzenzakalelayo kwefekthri, ukubambezeleka kwemojula engu-500 ms ngemva kokuqala kabusha.Uma singekho isidingo, sicela uqaphele. - ukusetha kabusha imojuli
Thumela: AT + SETHA KABUSHA
Thumela ngemva kokubuyisela ngempumelelo: KULUNGILE + SETHA KABUSHA
Ngemuva kokuthi imojula yokusebenzisa imiyalelo izobambezeleka ngo-500 ms ngemva kokuqala kabusha. - setha imodi yesigqila esiyinhloko
Thumela: AT + ROLE [para1] Thumela ngemva kokubuyisela ngempumelelo: KULUNGILE + Setha: [para1]
