nRF51822 nrfutil dfu ble

[Rajneesh]

Hello Nordic team

I am working on nRF51822 MCU.

My question is I can generate the DFU zip file and it working with nRFConnect and nRF Tool Box mobile application. But when I am trying to upload the file via nrfutill dfu ble it gave following errors:

No target selected. Default device name: DfuTarg is used.
Please select connectivity serial port:
0 : COM8 - 682271192
1 : COM17 - 681155878
Enter your choice: : 0

TypeError: __init__() got an unexpected keyword argument 'dfu_version'
Failed to execute script __main__

I used following command:

nrfutil dfu ble -ic NRF52 -pkg app_dfu_package.zip -p COM3 -n "MyDevice" -f

Also, help me how to use nRFConnect PC software to upload DFU file?

Please help me why above error I received and how to use nRFConnect PC software to send DFU file.

Any help will be appreciated.

Hi.

You have a nRF51822 board?

But you have put NRF52 in you nrfutil command.

Try:

nrfutil dfu ble -ic NRF51 -pkg app_dfu_package.zip -p COM3 -n "MyDevice" -f

Note that the --help option is useful if you are unsure what your command should be.

 nrfutil dfu ble --help
Usage: nrfutil dfu ble [OPTIONS]

  Perform a Device Firmware Update on a device with a bootloader that
  supports BLE DFU. This requires a second nRF device, connected to this
  computer, with connectivity firmware loaded. The connectivity device will
  perform the DFU procedure onto the target device.

Options:
  -pkg, --package PATH            Filename of the DFU package.  [required]
  -ic, --conn-ic-id [NRF51|NRF52]
                                  Connectivity IC family: NRF51 or NRF52
                                  [required]
  -p, --port TEXT                 Serial port COM port to which the
                                  connectivity IC is connected.
  -cd, --connect-delay INTEGER    Delay in seconds before each connection to
                                  the target device during DFU. Default is 3.
  -n, --name TEXT                 Device name.
  -a, --address TEXT              BLE address of the DFU target device.
  -snr, --jlink_snr TEXT          Jlink serial number for the connectivity IC.
  -f, --flash_connectivity        Flash connectivity firmware automatically.
                                  Default: disabled.
  --help                          Show this message and exit.

Best regards,

Andreas

Hi Andreas

As I mentioned I have used nRF51822 board (custom designed board). 

I have mentioned 

nrfutil dfu ble -ic NRF52 -pkg app_dfu_package.zip -p COM3 -n "MyDevice" -f


command which is the typo. I have tried with nRF51.

So, your reply doesn't help me. And I know --help command.

Thanks

Raj
