典型应用开发示例

Profile初始化

下图展示了Profile初始化：

@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: +VER=FSC-BT1038,V1.1.2,20250118 bt -> host: +PROFILE=24747 bt -> host: +SPPSTAT=1 bt -> host: +GATTSTAT=1 bt -> host: +A2DPSTAT=1 bt -> host: +AVRCPSTAT=1 bt -> host: +HFPSTAT=2 bt -> host: +BISSTAT=1 bt -> host: +CISSTAT=1 bt -> host: +DEVSTAT=7 （可发现打开,手机可以找到bt且可以连接） @enduml

修改参数

下图展示修改设备名为CARKIT的过程：

@startuml hide footbox skinparam sequenceMessageAlign center box #LightBlue participant Host as host participant Blueware as bt end box 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-BT1038-1E49 host -> bt: AT+NAME=CARKIT,0 bt -> host: OK host -> bt: AT+NAME bt -> host: +NAME=CARKIT @enduml

MCU 修改任何参数前，建议先查询再修改最后校验。MCU 修改设备名为 CARKIT 参考代码示例如下：

 1void change_name(void)
 2{
 3    uart_send("AT+NAME\r\n");
 4    if(uart_read("+NAME",name_buf))
 5    {
 6        if(memcmp(name_buf,"CARKIT",6))
 7        {
 8            uart_send("AT+NAME=CARKIT,0\r\n");      //defalut disable MAC address suffix
 9            uart_send("AT+NAME\r\n"); // read bt name
10            if(uart_read("+NAME",name_buf))
11            {
12                if(memcmp(name_buf,"CARKIT",6))
13                {
14                    //change name fail
15                }
16                else
17                {
18                    //change name success
19                }
20            }
21        }
22    }
23}
