Hello,
we want to add to our in-production solution the option do DFU OTA.
So we followed this step-by-step guide: https://devzone.nordicsemi.com/b/blog/posts/getting-started-with-nordics-secure-dfu-bootloader
We're using nRF52840-Preview-DK with Softdevice S132 v4.0.2. The Softdevice is installed on the device.
By creating the Bootloader we generated the private key (dfu01.pem) and saved it the keys to dfu_public_key.c. Now we execute in this folder: nRF5_SDK_13.1.0/examples/dfu/bootloader_secure_ble the command
make -C pca10040_debug/armgcc/ default flash
The DK starts advertising as DfuTarg.
Then we packaged our existing (and working) app to be sent by DFU. Therefore we used the following command:
nrfutil pkg generate --debug-mode --hw-version 52 --application pca10040/s132/armgcc/_build/nrf52832_xxaa.hex --sd-req 0x98 --key-file dfu01.pem app_dfu_package_debug.zip
Now by actually doing the Update using the nRF Connect App by iOS or by Android it always fails.
Here is the log of the Android App:
