Hi Hung, I'm using the NRF52 as a DFU controller for an STM32, therefore I would like to make a quick check to validate whether the STM has a valid app or not, and I would like to store the CRC of the STM in the NRF in order to be able to check the firmware version in the iOS app, which talks to the NRF via BLE. I hadn't considered modifying the settings structure, I think that's a great idea. Thanks for the suggestion!

Hi Andy,

All you need are included in the bootloader setting (CRC of application, bootloader version). I don't know why you need to store them separately.

Please have a look here.

If you want to store extra data, I think it's easiest to modify the bootloader setting structure to add your own data in.
