Secure DFU - Issue in updating the application.

Rishi

Hello, I am trying to implement OTA firmware update using Secure DFU.

SDK - 12.2

Softdevice - s132

Board - PCA10040 (nRF52)

I followed instructions mentioned here

Issues:

  • Once the bootloader code has been uploaded, device advertises as DFUTARG.

  • Able to connect to the device.

  • When I select .zip packet or .bin + .dat package, the following changes can be seen: "Initialising", "DFU starting" followed by immediate "Disconnected".

  • This is common to both nRF Connect and nRF Toolbox.

  • The procedure works fine with test_bootloader and test_hrm example.

  • Also, I am not generating a bootloader settings file as I just want to work with default settings.

Am I missing something, that is not mentioned on the link provided above?
