指令格式

AT+Command{=Param1{,Param2{,Param3…}}}<CR><LF>

All commands start with “AT”, end with <CR><LF>
<CR> means “carriage return”, corresponds to hex value 0x0D
<LF> means “line feed”, corresponds to hex value 0x0A
If Command has Parameter, Parameter follows behind ‘=’
If Command has multiple Parameters, Parameter must be separated by ‘,’
If Command has Response, Response starts with <CR><LF>, ends with <CR><LF>
Module will always report command’s execution result by using “OK” for success or “ERROR” for failure
所有的指令使用 AT 开头，使用 <CR><LF> 结尾
<CR> 代表回车符，对应 HEX 为 0x0D
<LF> 代表换行符，对应 HEX 为 0x0A
若指令包含参数，参数应使用 = 分隔
若指令包含多项参数，参数应使用 , 分隔
若指令有响应返回，响应使用 <CR><LF> 开始，使用 <CR><LF> 结束
模组应当总是返回指令执行的结果 (成功返回 OK，失败时返回 ERR<code>)

Example:
读取模块经典蓝牙名称
<< AT+NAME
>> +NAME=FSC-BT1035XXXX
>> OK

Example:
当没有来电时接听来电
<< AT+HFPANSW
>> ERROR

Event格式

<CR><LF>+Indication{=Param1{,Param2{,Param3…}}}<CR><LF>

所有的事件使用<CR><LF>开始, 使用<CR><LF>结束
若事件包含参数, 参数应位于 “=” 后面
若事件包含多项参数, 参数应使用 “,” 分割

Example:
手机端通过SPP协议发送”1234567890”
>> +SPPDATA=10,1234567890

Profile初始化及修改参数

下图展示了Profile初始化以及修改名称

MCU 修改设备名CARKIT参考代码

void change_name(void)
{
    uart_send("AT+NAME\r\n");
    if(uart_read("+NAME",name_buf))
    {
        if(memcmp(name_buf,"CARKIT",6))
        {
            uart_send("AT+NAME=CARKIT,0\r\n");      //defalut disable MAC address suffix
            uart_send("AT+NAME\r\n"); // read bt name
            if(uart_read("+NAME",name_buf))
            {
                if(memcmp(name_buf,"CARKIT",6))
                {
                    //change name fail
                }
                else
                {
                    //change name success
                }
            }
        }
    }
}

Note

修改任何参数建议先查询再修改最后校验:
