典型应用开发示例

初始化及参数修改

模块Profile初始化及参数修改，响应事件示例如下：

@startuml hide footbox skinparam sequenceMessageAlign center box #LightBlue participant Host as host participant Blueware as bt end box rnote over host, bt: Profile初始化 bt -> host: +PWRSTAT=1 bt -> host: +SPPSTAT=1 bt -> host: +GATTSTAT=1 bt -> host: +VER=BT1036,V2.8.7,20250306 (示例固件版本号，请以实际为准) bt -> host: +PROFILE=339 (通用默认，使能SPP、GATT Server、HFP-AG、A2DP Source、AVRCP Target) bt -> host: +A2DPSTAT=1 bt -> host: +AVRCPSTAT=1 bt -> host: +HFPSTAT=1 bt -> host: +DEVSTAT=1 bt -> host: +DEVSTAT=7 (使能设备可发现,手机可以找到该bt蓝牙设备且可以建立连接) rnote over host, bt: 修改蓝牙名称CARKIT,且不带地址码后缀,并校验 host -> bt: AT+NAME bt -> host: AT+NAME=FSC-BT1036-188A bt -> host: OK host -> bt: AT+NAME=CARKIT,0 bt -> host: OK host -> bt: AT+NAME bt -> host: +NAME=CARKIT @enduml

接收模式应用

Note

出厂固件如果是收发一体程序,程序默认profile=339, 需发送AT+PRFOILE=1195配置成音频接收模式 (打开SPP,GATT Server,HFP Sink,A2DP Sink,AVRCP-Controller,PBAP)

1.手机与模块建立连接并通过AT指令远程控制拨打电话，开发示例如下：

@startuml hide footbox skinparam sequenceMessageAlign center box #LightBlue participant Host as host participant Blueware as bt end box rnote over host, bt: Profile初始化 bt -> host: +PROFILE=1195 bt -> host: ... bt -> host: +DEVSTAT=7 rnote over host, bt: 手机搜索BT并发起连接 bt -> host: +PAIRREQ=797353,5C873026D673,Yui bt -> host: +PAIRED=0,5C873026D673,Yui bt -> host: +AVRCPSTAT=3 bt -> host: +A2DPSTAT=2 bt -> host: +HFPIBR=1 bt -> host: +A2DPSTAT=3 (A2DP已连接) bt -> host: +A2DPDEV=5C873026D673,Yui bt -> host: +DEVSTAT=1 bt -> host: +HFPSTAT=3 (HFP已连接) bt -> host: +HFPDEV=5C873026D673,Yui bt -> host: +HFPSIG=5 (手机的网络信号强度) bt -> host: +HFPBATT=4 (手机的电池电量) bt -> host: +HFPROAM=1 (手机的漫游状态) bt -> host: +HFPNUM=86188xxxx9792 (手机号码) bt -> host: +HFPMANU=AppleInc.

2.手机与模块建立连接并通过AT指令远程控制音乐播放/暂停，上下曲切换，开发示例如下：

@startuml hide footbox skinparam sequenceMessageAlign center box #LightBlue participant Host as host participant Blueware as bt end box rnote over host, bt: 手机端打开音乐播放器播放音乐 bt -> host: +A2DPSTAT=5 (音乐播放中) bt -> host: +PLAYSTAT=1 bt -> host: +TRACKINFO=Paris,Caro Emerald,The Shocking Miss Emerald bt -> host: +TRACKSTAT=1,9,287 bt -> host: +TRACKSTAT=1,10,287 bt -> host: +TRACKSTAT=1,11,287 bt -> host: +TRACKINFO=I live deep in symmetry,Paris — Caro Emerald,The Shocking Miss Emerald bt -> host: +TRACKSTAT=1,16,287 bt -> host: +TRACKSTAT=1,17,287 bt -> host: +TRACKSTAT=1,18,287 host -> bt: AT+PAUSE (暂停播放) bt -> host: OK bt -> host: +PLAYSTAT=2 (媒体播放器状态，示例中参数2为暂停) bt -> host: +A2DPSTAT=4 host -> bt: AT+PLAY(恢复播放) bt -> host: OK bt -> host: +A2DPSTAT=5 bt -> host: +PLAYSTAT=1 bt -> host: +TRACKINFO=Paris,Caro Emerald,The Shocking Miss Emerald bt -> host: +TRACKSTAT=1,28,287 bt -> host: +TRACKSTAT=1,29,287 bt -> host: +TRACKSTAT=1,30,287 bt -> host: +TRACKINFO=In this room of disconnect,Paris — Caro Emerald,The Shocking Miss Emerald bt -> host: +TRACKSTAT=1,31,287 bt -> host: +TRACKSTAT=1,33,287 host -> bt: AT+FORWARD (切换下一曲) bt -> host: OK bt -> host: +TRACKSTAT=1,0,187 bt -> host: +TRACKINFO=Ocean and Dreams,Aria Flux,Ocean and Dreams bt -> host: +TRACKSTAT=1,0,187 bt -> host: +TRACKINFO=Ocean and Dreams - Aria Flux,Ocean and Dreams — Aria Flux,Ocean and Dreams bt -> host: +TRACKSTAT=1,2,187 host -> bt: AT+FORWARD (切换下一曲) bt -> host: OK bt -> host: +TRACKSTAT=1,0,195 bt -> host: +TRACKINFO=Tangled Up,Caro Emerald,The Shocking Miss Emerald bt -> host: +TRACKSTAT=1,1,195 bt -> host: +TRACKSTAT=1,2,195 bt -> host: +TRACKSTAT=1,3,195 host -> bt: AT+STOP (停止播放) bt -> host: OK bt -> host: +PLAYSTAT=2 bt -> host: +A2DPSTAT=4 @enduml

Note

FSC-BT1036C默认PROFILE为339,即同时启用经典蓝牙音频发射功能以及SPP，GATT_Server；模块默认为模拟输入，如需要使用I2S输入请参考指令AT+I2SCFG，配置I2S后需要重启才能生效

PBAP应用

Note

SOC音频模块部分固件不支持下载联系人时自动连接PBAP, 需发送AT+PBCONN连接PBAP再下载
