Profile Initialization

Module Profile initialization, response event examples are as follows:

@startuml hide footbox skinparam sequenceMessageAlign center box #LightBlue participant Host as host participant Blueware as bt end box rnote over host, bt: Profile initialization bt -> host: +DEVSTAT=0 bt -> host: +HFPSTAT=1 bt -> host: +A2DPSTAT=1 bt -> host: +AVRCPSTAT=1 bt -> host: +PBSTAT=1 bt -> host: +SPPSTAT=1 bt -> host: +GATTSTAT=1 bt -> host: +VER=FSC-BT1026C,V4.9.4,20230428 bt -> host: +DEVSTAT=7 bt -> host: +PROFILE=1195 @enduml

Parameter Modification

Modify Bluetooth Name

@startuml hide footbox skinparam sequenceMessageAlign center box #LightBlue participant Host as host participant Blueware as bt end box rnote over host, bt: Change Bluetooth name host -> bt: AT+NAME bt -> host: +NAME=FSC-BT1026C host -> bt: AT+NAME=My_Bluetooth,1 bt -> host: OK host -> bt: AT+NAME bt -> host: +NAME=My_Bluetooth0012 @enduml

Before the MCU modifies any parameters, it is recommended to first query, then modify, and finally verify. For the MCU to modify the device name to CARKIT, the reference code example is as follows:

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
                }
            }
        }
    }
}
