nRF52840 + nRF Connect v2.6.1

Hi everyone,

I'm playing with the nRF52840 dongle (PCA10059) but I'm not able to program it using nRF Connect (v2.6.1).

I open the sw and connect the dongle, choose the COM port, the dongle starts to blink red and memory regions are correctly read from the dongle.

After that, I choose the hex file but none of the buttons on the right is enabled, except for the "Reset" button.

I also tried other nRF Connect's apps (like RSSI Viewer and Bluetooth Low Energy) and they are flashed correctly on the dongle.

I think both dongle and software are woking correctly so: am I missing some step to flash the desired hex file on the board?

For now I've tried ready-to-use hex files from examples/thread/experimental (taken from nRF5SDKforThreadv011084a130f) and also some self-made builds of the last openthread cli and ncp binaries.

Any help is welcome, I have the feeling that I'm making a silly mistake.


Thank you in advance

Paul

  • Hi.

    Did you try to follow the steps found in the nRF52840 Dongle Programming Tutorial?

    1. Open nRF Connect for Desktop and launch the Programmer app.
    2. Press the reset button to put the Dongle in DFU mode. This is not needed if the currently running application uses the DFU trigger library. Note that the reset button is the sideway button right next to the more obvious SW1 button on the Dongle:
    3. Select the dongle in the dropdown in the upper left corner if it is shown.
    4. Click "Add HEX file" to select the application hex file to program onto the dongle.
    5. Click "Write" to write the firmware to the dongle.

    When upgrade completes the device will reset and the dongle will no longer show up in nRF Connect unless the application used DFU Trigger Library is used, as it is no longer in DFU mode.

    Which of these steps were you unable to do? Step 5?

    Best regards,

    Andreas
