Mawu Oyamba

Iyi ndi gawo la SMD BLE lomwe limagwiritsidwa ntchito mu BLE Bee yathu ndi Xadow BLE. Zimakhazikitsidwa ndi TI cc2541 chip, imathandizira ma network amphamvu kuti amangidwe ndi ndalama zotsika mtengo komanso zoyenera kwambiri kugwiritsa ntchito mphamvu zamagetsi. Gawoli ndi laling'ono komanso losavuta kugwiritsa ntchito, ndi firmware yokonzedweratu ya wopanga, mutha kupanga mwachangu kulumikizana kwa BLE kudzera pa AT command yake. Kuthandizira kulumikizana kwa BLE ndi iphone, ipad ndi Android 4.3.

AT malamulo & kasinthidwe

1. Funsani adilesi yaku MAC
   Tumizani: AT + ADDR?
   Tumizani mutabweza bwino: CHABWINO + LADD: Adilesi ya MAC (adilesi ya zingwe 12)
2. Funsani mtengo wa baud
   Tumizani: AT+BAUD? Tumizani pambuyo pa kubwerera bwino: OK + Pezani: [para1] Kuchuluka kwa para1: 0 ~ 8. Magawo ofanana ndi: 0 akuyimira 9600, 1, 2, 9600, 38400, m'malo mwa woimira 57600, 115200, 5 , 4800, 6, 7 ikuyimira 1200, 1200 2400. Chiwerengero chokhazikika cha baud ku 9600.
3. Khazikitsani mtengo wa baud
   Tumizani: AT+BAUD[para1] Tumizani mutabwerera bwino: OK+Set:[para1] Example: tumizani: AT + BAUD1, kubwerera: OK + Ikani: 2.Mlingo wa baud wakhazikitsidwa ku 19200.
   Zindikirani: mutatha kusintha kwa 1200, gawo silidzathandiziranso makonzedwe a lamulo la AT, ndikusindikiza PIO0 pansi pa standby, gawo likhoza kubwezeretsanso Mapangidwe a fakitale. pamagetsi, magawo atsopano amatha kugwira ntchito.
4. kuchokera ku chipangizo cholumikizidwa ku adilesi ya bluetooth yotchulidwa
   Tumizani: AT+CON[para1] Tumizani mutabwerera bwino: OK+CONN[para2] Para2 osiyanasiyana ndi: A, E, F

Zindikirani: pambuyo kuphedwa malangizo, chofunika magetsi, ikani magawo a chivomerezo.
10. funso lofanana ndi mawu achinsinsi
    Tumizani: AT + PASS?
    Tumizani mutabwerera bwino: CHABWINO + PASS: [para1] Para1 osiyanasiyana ndi 000000 ~ 999999, kusakhulupirika ndi 000000.
11. pairing set password
    Tumizani AT + PASS [para1] Tumizani mutabwerera bwino: CHABWINO + Khazikitsani: [para1]
12. bwezeretsani Fakitale Zikhazikiko
    The AT + RENEW kutumiza
    Tumizani mukabwerera bwino: CHABWINO + TSOPANO
    Bwezeretsani gawo la Zikhazikiko za fakitale yokhazikika, Zosintha za module zidzabwezeretsedwanso, kubwerera ku fakitale ndi chikhalidwe cha fakitale ya fakitale, mochedwetsa gawo 500 ms mutatha kuyambiranso.Ngati palibe chifukwa, chonde samalani.
13. kukonzanso module
    Tumizani: AT + RESET
    Tumizani mukabwerera bwino: CHABWINO + BWINO
    Pambuyo pa gawo la malangizo lidzachedwa 500 ms mutatha kuyambiranso.
14. khazikitsani njira ya master-kapolo
    Tumizani: AT + ROLE [para1] Tumizani mutabwerera bwino: CHABWINO + Khazikitsani: [para1]
