Yuav luag txhua yam khoom siv Bluetooth muaj MCU, tab sis Yuav Ua Li Cas Sib Txuas Lus Ntawm MCU thiab Bluetooth Module? Hnub no koj yuav kawm txog yuav ua li cas.
Siv BT906 ua piv txwv:
1. Txuas MCU thiab Bluetooth module kom zoo.
Feem ntau koj yuav paub tias tsuas yog xav tau siv UART (TX / RX) ces tuaj yeem sib txuas lus.
Koj lub MCU TX txuas nrog BT906 module's RX.Thov xyuas seb koj puas tau ua li no?
Yog tias koj tau lees paub tias tsis muaj teeb meem hauv Circuit Court, ces peb mus rau kauj ruam 2
2. Nco ntsoov tias Hardware Part yog lawm.
1) Txuas TX RX ntawm lub module rau lub computer los ntawm 3.3V USB Hloov mus rau Serial Port
2) Qhib 'Feasycom Serial Chaw nres nkoj', xaiv qhov chaw nres nkoj, Baurd tus nqi: 115200, Xaiv: Kab Tshiab
3) Xa ''AT + VER'', Yog tias muaj lus teb: + VER = xxxxx, ces nws txhais tau tias kho vajtse nws zoo.
3.Ua kom paub tseeb tias qhov software ua tau zoo.
1) Xa ''AT + MODE = 2, ces nws yuav hloov mus rau hauv hom zais
2) Siv xov tooj ntawm tes txuas nrog cov cuab yeej zais npe hu ua Feasycom
3) Qhib cov ntaub ntawv txt xaiv tus cursor
4) Xa hexadecimal
41 54 2B 48 49 44 53 45 4E 44 3D 32 2C 00 04 0D 0A. Ces cellphone yuav tau txais: a
A T + H I D S END = 2 , \r \n
00: "tswj yuam sij" tus nqi
04: ''Hid value'' ntawm ''a''
