buttonless DFU SDK v14.0 problems

Allen

Hello,

I am having difficulty downloading an application using the sample images provided. It looks like the application boots into the bootloader, there is a brief message that it is downloading but then the name changes to DFUTEST and LEDs 2 and 3 are lit.

The sample application I am trying to download is blinky. I verified that it builds and runs in the debugger. When I ran "nrfutil pkg generate ..." I used a private key that I generated. Could this be the problem? If it is, where is the private key used for the sample images?

Thank you in advance!

    I figured it out. I did not realize that the ble_app.zip was the sample application to download that was signed with the correct keys. Once I realized that I:

    1. erased flash
    2. programmed softdevice_bootloader_secure_ble_debug_without_bonds_s132.hex
    3. reset
    4. open nRFConnect
    5. downloaded ble_app_buttonless_dfu_without_bonds_s132.zip
