unable to program nRF52 Dongle through nRF Connect app (desktop)

Abhishek

Hi,

I am unable to program the nRF52 Dongle. What I see is that the "Write" option is not highlighted.

Though the Bootloader and Softdevice are already there on the dongle. 

Thanks

Abhishek

    Hi Edvin,

    Now I have set-up the SWD connections to debug where I could see that the code is stuck in between.

    If you need to support on this ticket please refer to this:

    I am closing this post as I created another ticket for it.

    Thanks for your support.

    Then I tried the example in the SDK for the dongle itslef.

    \nRF5_SDK_15.2.0_9412b96\examples\ble_peripheral\ble_app_blinky\pca10059

    I built this example and tried to program with the .hex file it showed the same indications in nRF Connect.

     Did you remember to program the softdevice when programming this application?

    It should look like this in nRF Programmer (in nRF Connect):

    If successful, it should still say "Reopen device failed: Timeout while waiting for device ..." and "Device not found due to failure during DFU".

    Also, the LED doesn't blink in the ble_app_blinky application, but the green LED will be constantly on while advertising. If you connect to it, it should change to red LED constant on.

    BR,

    Edvin
