AT commands & Configuration

1. Nug qhov chaw nyob hauv MAC
   Xa: AT + ADDR?
   Xa tom qab ua tiav rov qab: OK + LADD: MAC chaw nyob (chaw nyob rau 12 txoj hlua)
2. Nug tus nqi baud
   Xa: AT + BAUD? Xa tom qab ua tiav kev xa rov qab: OK + Tau: [para1] Scope ntawm para1: 0 ~ 8. Cov tsis sib xws rau: 0 sawv cev rau 9600, 1, 2, 9600, 38400, sawv cev ntawm tus neeg sawv cev ntawm 57600, 115200, 5 , 4800, 6, 7 sawv cev rau 1200, 1200 2400. Lub neej ntawd baud tus nqi rau 9600.
3. Teem tus nqi baud
   Xa: AT + BAUD [para1] Xa tom qab ua tiav rov qab: OK + Teem: [para1] Example: xa: AT + BAUD1, xa rov qab: OK + Teem: 2.Tus baud tus nqi yog teem rau 19200.
   Nco tseg: Tom qab hloov mus rau 1200, module yuav tsis txhawb cov configurations ntawm AT hais kom ua, thiab nias lub PIO0 nyob rau hauv standby, module yuav rov qab tau lub Hoobkas nqis.Tsis pom zoo kom siv tus nqi baud.Tom qab teeb tus nqi baud, modules yuav tsum tau. ntawm hluav taws xob, cov txheej txheem tshiab tuaj yeem siv tau.
