Parameter Modification

Modify Bluetooth Name

Modify Name. Examples of AT command operations and response events 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: Change Bluetooth name
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

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
                }
            }
        }
    }
}
