就是怎么操作，流程，刚学的，特总结如下，对没有调试过BT，无从下手的新手们提供点素材。我也是现学现卖，原来没碰过，突然让调，就一头雾水，幸亏是个模块，只用AT指令就能搞定。

AT command deion

AT+BTIN  查找BT源

AT+BTK=”8888” is the pair code 配对密码

ATS102?

ATS102=$0180   will allow A2DP and AVRCP   禁止SPP，使能A2DP 和AVRCP

AT+BTC?

001F00

AT+BTN?

“LAIRD BTMMP 000151”

AT&F0 设置UART波特率

ATS512=4  连接并查找

ATS0=1  自动应答

ATZ  硬件复位

AT+BTN？  读模块的名字

PIN？

AT+BTT？                                                                       

0005C9000000 读对方BT的地址

ATI4

0016A4000161 读自己的BT地址

AT+APD 0005C9000000 to control your phone A2DP

CONNECT 0005C9000000,110D

AT+AVD 0005C9000000 to control your phone  AVRCP

CONNECT 0005C9000000,110E

AT+AVC44    play

AT+AVC45    stop

AT+AVC46    pause

AT+AVC4B    last song

AT+AVC4C    next song

AT+BTN=”GMY”  设置缺省连接name

ATI4？    BT设备地址

 

Phone ->A2DP -> module #1 -> Speaker(J7)

Flow:

at&F* reset all setting on the module

atz will reboot the module

ats102=$0180 allows A2DP, and AVRCP

at+btk="8888" - is the pair code

aT+BTT will save the pairing setting

ATI4?

0016A4000161

At+btt?

0005C9000000

AT+APD0005C9000000     A2DP connect your phone

AT+AVD0005C9000000    AVRCPremote control

AT+AVC44    play

AT+AVC45    stop

AT+AVC46    pause

AT+AVC4B    last song

AT+AVC4C    next song
