Buttonless DFU - 'No bootloader was found' error

[vist]

I tried building and running the buttonless DFU example project. However I get the following UART output:

<error> app: No bootloader was found
<error> app: ERROR 4 [NRF_ERROR_NO_MEM] at C:\Users\vist\Downloads\nRF5_SDK_15.0.0_a53641a\nRF5_SDK_15.0.0_a53641a\examples\ble_peripheral\ble_app_buttonless_dfu\main.c:471
PC at: 0x00030DDB
<error> app: End of error report

It seems like it can download the softdevice by itself if the memory is erased but not the bootloader. Which bootloader am I supposed to download?

Hi,

The bootloader project can be found here: nRF5_SDK_15.0.0_a53641a /examples/dfu/secure_bootloader. There are some additional steps needed to build the bootloader so I'd recommend you to read through this blog post by Hung in order to get started.
