    Issue 1: Missing DFU Service

    Solution: You have to update the nRF Connect app, Secure DFU was added in the v4.4.x version and the current version is v4.8.1. You can see the features the latest version on Google Play, here is the link.

    Issue 2: DFU fails after generating package with the following command (or similar) nrfutil pkg generate --hw-version 1 --sd-req 0x80 --application-version 4 --application app.hex --key-file key.pem app_dfu_package.zip

    Solution: Incorrect hardware version used , it should be 51 for the nRF51822 and not 1 as shown in the nrfutil documentation.
