AT mirairo & Configuration

1. Bvunza iyo yemuno MAC kero
   Tumira: AT + ADDR?
   Tumira mushure mekudzoka kwakabudirira: OK + LADD: MAC kero (kero ye12 tambo)
2. Bvunza iyo baud rate
   Tumira: AT+BAUD? Tumira mushure mekubudirira kudzoka: OK + Tora: [para1] Chikamu chepara1: 0 ~ 8. Izvo zviyero zvinoenderana ne: 0 inomiririra 9600, 1, 2, 9600, 38400, pachinzvimbo chemumiriri we57600, 115200, 5 , 4800, 6, 7 inomiririra 1200, 1200 2400. The default baud rate kusvika 9600.
3. Isa chiyero chebhadhi
   Tumira: AT+BAUD[para1] Tumira mushure mekudzoka kwakabudirira: OK+Set:[para1] Example: tumira: AT + BAUD1, dzoka: OK + Set: 2.The baud rate yakagadzirirwa ku19200.
   Cherechedza: mushure mekushandura kune 1200, module haichazotsigiri zvigadziro zvemurairo weAT, uye chengetedza PIO0 pasi pekumira, module inogona kudzorera fekitari Settings.Usakurudzira kushandisa baud rate.Mushure mekugadzirisa chiyero chebhadhi, modules inofanira kuva pamagetsi, mitsva yakaiswa paramita inogona kushanda.
4. kubva pachigadzirwa chakabatana nekero yebluetooth yakataurwa
   Tumira: AT+CON[para1] Tumira mushure mekudzoka kwakabudirira: OK+CONN[para2] Para2 renji ndeye: A, E, F
   Example: kubva kukero yebluetooth ndeye: 0017EA0943AE, kutumira iyo AT + CON0017EA0943AE, module inodzoka: OK + CONNA kana OK + + CONNF CONNE kana OK.
5. midziyo yekubvisa inofananidza ruzivo

    Dzorera iyo default factory Settings module, iyo module Settings ichagadziriswa saka, kudzokera kufekitari ine mamiriro ekugadzirisa fekitari, kunonoka module 500 ms mushure mekutangazve.Kana pasina chikonzero, tapota chenjerera.
13. module reset
    Tumira: AT + RESET
    Tumira mushure mekudzoka kwakabudirira: OK + RESET
    Mushure mekuraira kwekuita module inononoka 500 ms mushure mekutangazve.
14. isa iyo tenzi-muranda mode
    Tumira: AT + ROLE [para1] Tumira mushure mekudzoka kwakabudirira: OK + Set: [para1]
