应用开发示例

1. 初始化及参数修改

模块Profile初始化修改蓝牙名称，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: +DEVSTAT=0 bt -> host: +PWRSTAT=1 bt -> host: +VER=BT936,V4.6.5,20220622 bt -> host: +PROFILE=339 bt -> host: +SPPSTAT=1 bt -> host: +GATTSTAT=1 bt -> host: +A2DPSTAT=1 bt -> host: -A2DPSTAT=1 bt -> host: +AVRCPSTAT=1 bt -> host: +HFPSTAT=1 bt -> host: -HFPSTAT=1 bt -> host: +DEVSTAT=1 bt -> host: +DEVSTAT=7 （可发现打开,手机可以找到bt且可以连接） bt -> host: +AUDROUTE=0 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-BT1036-1E49 host -> bt: AT+NAME=CARKIT,0 bt -> host: OK host -> bt: AT+NAME bt -> host: +NAME=CARKIT @enduml

2. 发射模式，搜索、连接、断开蓝牙耳机

2.1搜索蓝牙耳机

@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 host -> bt: AT+SCAN=1 bt -> host: +DEVSTAT=5 bt -> host: +DEVSTAT=13 bt -> host: OK bt -> host: +SCAN=1,-71,0,86677A027ADA,ZN108_7ADA,040680 bt -> host: +SCAN=2,-59,0,648FDB44048B,Xiaomi Buds 5,244404 bt -> host: +SCAN=3,-57,0,DC0D30402073,iMin TF2-34 2073,000680 bt -> host: +SCAN=4,-74,0,DC0D300005D1,FSC-BW246,000680 bt -> host: +SCAN=5,-69,0,AC198EAC5DFE,FR,2A410C bt -> host: +SCAN=6,-66,0,E0D8C4660C75,JMGO-N1 Pro-0127,2C043C bt -> host: +SCAN=7,-77,0,41421F318F8A,AB571X-TWS,240404 bt -> host: +SCAN=8,-55,0,A0B339DB5208,QUZHENGWEI,2A410C bt -> host: +DEVSTAT=5 bt -> host: +SCAN=E bt -> host: +DEVSTAT=7 @enduml

2.2连接主蓝牙耳机

@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 host -> bt: AT+FOCUS=648FDB44048B bt -> host: +A2DPSTAT=2 bt -> host: +PEERSTAT=648FDB44048B,2,1 bt -> host: +PAIRREQ=243705,648FDB44048B,Xiaomi Buds 5 bt -> host: +PAIRED=0,648FDB44048B,Xiaomi Buds 5 bt -> host: +A2DPSTAT=3(A2DP已连接) bt -> host: +DEVSTAT=5 bt -> host: +A2DPDEV=648FDB44048B,Xiaomi Buds 5 bt -> host: +AVRCPSTAT=3(AVRCP已连接) bt -> host: +PLAYSTAT=2 bt -> host: +PEERSTAT=648FDB44048B,3,1 bt -> host: +HFPSTAT=2 bt -> host: +HFPSTAT=3(HFP已连接) bt -> host: +HFPDEV=648FDB44048B,Xiaomi Buds 5 bt -> host: +PEERSTAT=648FDB44048B,3,3 @enduml

2.3连接副蓝牙耳机

@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 host -> bt: AT+FOCUS=,80C3BA3834B2 bt -> host: -A2DPSTAT=2 bt -> host: -PEERSTAT=80C3BA3834B2,2,1 bt -> host: +PAIRREQ=616247,80C3BA3834B2,CX Plus True Wireless bt -> host: +PAIRED=0,80C3BA3834B2,CX Plus True Wireless bt -> host: -A2DPSTAT=3 bt -> host: -A2DPDEV=80C3BA3834B2,CX Plus True Wireless bt -> host: -PEERSTAT=80C3BA3834B2,3,1 bt -> host: -HFPSTAT=2 bt -> host: -HFPSTAT=3 bt -> host: -HFPDEV=80C3BA3834B2,CX Plus True Wireless bt -> host: -PEERSTAT=80C3BA3834B2,3,3 @enduml

2.4音频路由管理

通过A2DP协议将音频发射到主、副蓝牙耳机

@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 host -> bt: AT+AUDROUTE=1 bt -> host: +AUDROUTE=1 bt -> host: OK bt -> host: +A2DPSTAT=5 bt -> host: +PLAYSTAT=1 bt -> host: -A2DPSTAT=5 bt -> host: +AUDMODE=1 bt -> host: +PEERSTAT=648FDB44048B,5,3 bt -> host: -PEERSTAT=80C3BA3834B2,5,3 @enduml

通过HFP协议将音频发射到主蓝牙耳机

@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 host -> bt: AT+AUDROUTE=2 bt -> host: +AUDROUTE=2 bt -> host: OK bt -> host: -A2DPSTAT=4 bt -> host: +PLAYSTAT=2 bt -> host: +A2DPSTAT=4 bt -> host: +AUDMODE=0 bt -> host: +HFPSTAT=4 bt -> host: +AUDMODE=2 bt -> host: +HFPAUDIO=1 bt -> host: +PEERSTAT=648FDB44048B,4,4 bt -> host: -PEERSTAT=80C3BA3834B2,4,3 bt -> host: +HFPSTAT=6 bt -> host: +PEERSTAT=648FDB44048B,4,6 @enduml

2.5断开连接

已连接两幅耳机，断开主蓝牙耳机

@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 host -> bt: AT+FOCUS=000000000000, bt -> host: +HFPSTAT=1 bt -> host: +A2DPSTAT=1 bt -> host: +DEVSTAT=7 bt -> host: +HFPSTAT=3 bt -> host: +AVRCPSTAT=1 bt -> host: +ACL=22,648FDB44048B bt -> host: +PEERSTAT=648FDB44048B,1,1 host -> bt: AT+A2DPSTAT(查询A2DP状态) bt -> host: -A2DPSTAT=5（副耳机仍为播放状态） bt -> host: -A2DPDEV=80C3BA3834B2,CX Plus True Wireless bt -> host: +A2DPSTAT=1 bt -> host: OK @enduml
