Failed to modify the Bluetooth name of matter (CON-1583)

[MaplestoryAlen]

I want to change the Bluetooth name, but I have tried many ways and cannot change the Bluetooth name,
May I ask how to allow users to customize BLE names? Additionally, I noticed that there is a 16 byte limit. Does this 16 byte limit require subtracting 4 bytes from the description code?

Method 1：

Change and set in menuconfig

Method 2：

void SetBLEDeviceName(void)
{
const char *deviceName = "Xz_NC";
chip::DeviceLayer::ConnectivityMgr().SetBLEDeviceName(deviceName);
}

Method 3：

#define CHIP_DEVICE_CONFIG_BLE_DEVICE_NAME_PREFIX “81MtCn01”

Do you want to change the BLE advertisement name, you can add as below in the file :

    memset(advData, 0, sizeof(advData));
    advData[index++] = 0x02;                                                                // length
    advData[index++] = CHIP_ADV_DATA_TYPE_FLAGS;                                            // AD type : flags
    advData[index++] = CHIP_ADV_DATA_FLAGS;                                                 // AD value
    advData[index++] = 0x04;                                                                // length
    advData[index++] = 0x9;                                            // AD type : flags
    advData[index++] = 'T';                                                 // AD value
    advData[index++] = 'S';                                                 // AD value
    advData[index++] = 'T';                                                 // AD value
    advData[index++] = kServiceDataTypeSize + sizeof(ESP32ChipServiceData);                 // length
    advData[index++] = CHIP_ADV_DATA_TYPE_SERVICE_DATA;                                     // AD type: (Service Data - 16-bit UUID)
    advData[index++] = static_cast<uint8_t>(ShortUUID_CHIPoBLEService.value & 0xFF);        // AD value
    advData[index++] = static_cast<uint8_t>((ShortUUID_CHIPoBLEService.value >> 8) & 0xFF); // AD value
