How to add buttonless_dfu and serial_dfu functions at the same time.

June6

Now the code in the application part has added the buttonless_dfu function, which has also been successfully implemented. But I ’m not familiar with serial_dfu, I don’t know how to continue to add serial_dfu function. And how to achieve coexistence of ble_dfu and serial_dfu in bootload code？

    I try to use pca10056_uart project, only use serial_dfu, will not use HWFC, the serial port baud rate is changed to 9600

    nrf_drv_uart_config_t uart_config = NRF_DRV_UART_DEFAULT_CONFIG;

    uart_config.pseltxd   = TX_PIN_NUMBER;
    uart_config.pselrxd   = RX_PIN_NUMBER;
    uart_config.pselcts   = CTS_PIN_NUMBER;
    uart_config.pselrts   = RTS_PIN_NUMBER;
//    uart_config.hwfc      = NRF_DFU_SERIAL_UART_USES_HWFC ?
//                                NRF_UART_HWFC_ENABLED : NRF_UART_HWFC_DISABLED;
		uart_config.hwfc      = NRF_UART_HWFC_DISABLED;
		uart_config.baudrate  = 2576384; // Corresponds to 9600 baud
    uart_config.p_context = &m_serial;

    The following changes were made in the dfu_transport_serial.py file in the pc-nrfutil-master \ nordicsemi \ dfu path

    class DfuTransportSerial(DfuTransport):

    DEFAULT_BAUD_RATE = 9600 #115200
    DEFAULT_FLOW_CONTROL = False #True
    DEFAULT_TIMEOUT = 30.0  # Timeout time for board response
    DEFAULT_SERIAL_PORT_TIMEOUT = 1.0  # Timeout time on serial port read
    DEFAULT_PRN                 = 0
    DEFAULT_DO_PING = True

    OP_CODE = {
        'CreateObject'          : 0x01,
        'SetPRN'                : 0x02,
        'CalcChecSum'           : 0x03,
        'Execute'               : 0x04,
        'ReadError'             : 0x05,
        'ReadObject'            : 0x06,
        'GetSerialMTU'          : 0x07,
        'WriteObject'           : 0x08,
        'Ping'                  : 0x09,
        'Response'              : 0x60,
    }

    Execute 

    nrfutil dfu serial -pkg production_DFU.zip -p COM14 -b 9600
    instruction still error

    Could you verify that you can do serial DFU with the stock serial DFU example (not my combination example) ? it's the uart projects inside \examples\dfu\secure_bootloader

    I verified and reported this error: 

    pc_ble_driver_py.exceptions.NordicSemiException: Unexpected Executed OP_CODE.

    How does it has anything to do with pc_ble_driver_py ? 
    Could you post the full logging of the command line ? 
    Please test with the uart example in \examples\dfu\secure_bootloader.

    I used the uart examples in \ examples \ dfu \ secure_bootloader. The full log of the command line is as follows:
