nrf8001-DK & ble_uart_project_with_dfu_template - Error during firmware upload

Question

Hi, 
 I am currently working with the nrf8001-DK. I've connected the nRF8001/nRF24L01+ shield adapter to an Arduino UNO R3. 
 I've run the ble_uart_project_with_dfu_template with the specific configuration of the MCU to nRF8001 PIN connection according to github.com/.../ble-sdk-arduino 
 aci_state.aci_pins.board_name = BOARD_DEFAULT; //See board.h for details REDBEARLAB_SHIELD_V1_1 or BOARD_DEFAULT
 aci_state.aci_pins.reqn_pin = SS; //SS for Nordic board, 9 for REDBEARLAB_SHIELD_V1_1
 aci_state.aci_pins.rdyn_pin = 3; //3 for Nordic board, 8 for REDBEARLAB_SHIELD_V1_1
 aci_state.aci_pins.mosi_pin = MOSI;
 aci_state.aci_pins.miso_pin = MISO;
 aci_state.aci_pins.sck_pin = SCK;

 aci_state.aci_pins.spi_clock_divider = SPI_CLOCK_DIV8;

 aci_state.aci_pins.reset_pin = 4; //4 for Nordic board, UNUSED for REDBEARLAB_SHIELD_V1_1
 aci_state.aci_pins.active_pin = UNUSED;
 aci_state.aci_pins.optional_chip_sel_pin = UNUSED;

 aci_state.aci_pins.interface_is_interrupt = false;
 aci_state.aci_pins.interrupt_number = 1;
 
 I've tried to upload the ble_heart_rate_template_with_simulated_battery_service.cpp.hex (see forum.arduino.cc/index.php and www.theengineeringprojects.com/.../hex-file-arduino.html) . I am using the Window's nRF Master Control Panel and the nRF51822 Development Dongle. 
 
 But I got this error. 
 
 Any ideas? Thank you in advance

Hi Modes, 
 The current Master Control Panel application on PC may not be compatible with the bootloader.
I would suggest you to try with the nRFToolbox app on Android or iOS.
Please follow the instruction in this link . 
 In addition you can test with earlier version of MCP on PC. It should be version 3.6. You can have a look here .
