ARDUINO CC2541 Nihokikorangi V4.0 HM-11 BLE Pukapuka Kaiwhakamahi Kōwae
Kupu Whakataki
He kōwae SMD BLE tenei e whakamahia ana i roto i ta maatau BLE Bee me Xadow BLE. I ahu mai i te maramara TI cc2541, ka taea te hanga i nga pona whatunga pakari me te iti o nga utu pire-a-rauemi me te tino pai mo nga punaha kohi hiko. He iti te kōwae me te ngawari ki te whakamahi, me te firmware o mua o te kaihanga, ka taea e koe te hanga i nga korero BLE ma tana whakahau AT. Te tautoko i nga korero BLE me te iphone, ipad me te Android 4.3.

Nga whakahau AT & Whirihoranga
- Uia te wahitau MAC taketake
Tukuna: AT + ADDR?
Tukuna i muri i te hokinga angitu: OK + LADD: MAC address (whitau mo te aho 12) - Uia te reiti o te baud
Tukuna: AT+BAUD? Tukuna mai i muri i te hokinga angitu: OK + Tikina: [para1] Te whānuitanga o te para1:0 ~ 8. Ko nga tawhā e rite ana ki: 0 e tohu ana i te 9600, 1, 2, 9600, 38400, mo te mangai o te 57600, 115200, 5 , 4800, 6, 7 e tohu ana i te 1200, 1200 2400. Ko te reeti baud taunoa ki te 9600. - Tautuhia te reiti o te baud
Tukuna: AT+BAUD[para1] Tukuna i muri i te hokinga angitu: OK+Tautuhi:[para1] Example: tuku: AT + BAUD1, hoki mai: OK + Tautuhi: 2. Kua whakaritea te reiti baud ki te 19200.
Tuhipoka: i muri i te huringa ki te 1200, ka kore e tautokohia e te kōwae nga whirihoranga o te whakahau AT, ka pehi i te PIO0 i raro i te tatari, ka taea e te kōwae te whakahoki i nga Tautuhinga wheketere.Kaua e tūtohu kia whakamahi i te reiti baud.I muri i te tautuhi i te reiti baud, me waiho nga waahanga. i runga i te hiko, ka whai mana nga tawhā huinga hou. - mai i te taputapu hono ki te wahitau Nihokikorangi kua tohua
Tukua: AT+CON[para1] Tukuna i muri i te hokinga angitu: OK+CONN[para2] Ko te awhe Para2: A, E, F
Example: mai i te wāhitau bluetooth ko: 0017EA0943AE, te tuku AT + CON0017EA0943AE, ka hoki mai te kōwae: OK + CONNA ranei OK + + CONNF CONNE OK ranei. - taputapu tango korero e rite ana
Tukuna: AT + CLEAR
Tukuna i muri i te hokinga angitu: OK +
CLEAR Maamaa te angitu i hono nga korero waehere wahitau taputapu. - aratau mahi kōwae uiui
Tukuna: AT + MODE?
Tukuna i muri i te hokinga angitu: OK + Tikina: [para] Para: ko te awhe o te 0 ~ 2. Ko te 0 e tohu ana i te aratau whakawhiti, mo te hoko PIO + mana mamao + 1 whakawhiti, 2 tohu whakawhiti + aratau mana mamao.Ko te taunoa ko 0. - tautuhi te aratau mahi kōwae:
Tukua: AT + MODE [] Tukuna i muri i te hokinga angitu: OK + Tautuhi: [para] - ingoa taputapu patai
Tukuna: AT + INGOA?
Tukuna i muri i te hokinga angitu: OK + INGOA [para1] - tautuhia te ingoa taputapu
Tukuna: AT + Ingoa [para1] Tukuna i muri i te hokinga angitu: OK + Tautuhi: [para1] Example: Tautuhia te ingoa o te taputapu ki Seeed, ka tukuna te AT + NAMESeeed, hoki mai OK + Tautuhi: Seeed AT i tenei wa, kua hurihia te ingoa o te kōwae bluetooth ki Seeed. Tuhipoka: i muri i te mahi tohutohu, e hiahiatia ana ki te hiko, whakaritea nga tawhā o te whakaaetanga. - Uiui e rite ana ki te kupuhipa
Tukuna: AT + PASS?
Tukuna i muri i te hokinga angitu: OK + PASS: [para1] Ko te awhe Para1 ko 000000 ~ 999999, ko te taunoa ko 000000. - kupuhipa tautuhi takirua
Tukuna te AT + PASS [para1] Tukuna i muri i te hokinga angitu: OK + Tautuhi: [para1] - whakahokia Tautuhinga wheketere
Ko te AT + RENEW tuku
Tukuna mai i muri i te hokinga angitu: OK + RENEW
Whakahokia te waahanga Tautuhinga wheketere taunoa, ka tautuhia ano nga Tautuhinga waahanga, na, ka hoki ki te wheketere me te mana o te wheketere taunoa, whakaroa te waahanga 500 ms i muri i te tiimatanga.Ki te kore e hiahiatia, kia tupato. - tautuhi kōwae
Tukuna: AT + RESET
Tukuna i muri i te hokinga angitu: OK + RESET
Whai muri i te kōwae mahi tohutohu ka whakaroa te 500 ms i muri i te tiimatanga. - whakaturia te aratau rangatira-pononga
Tukuna: AT + ROLE [para1] Tukuna i muri i te hokinga angitu: OK + Tautuhi: [para1]
Example Waehere
// rangatira
//pononga
