Hi,

For the nRF51822 I highly recommend using SDK 12.3, which is the latest SDK version supporting the nRF51 series. It also contains the secure DFU bootloader, which supports signing the firmware image so that the device only accepts upgrades coming from you.

The application gets erased when you upgrade the bootloader. Therefore you should first upgrade the bootloader, then upgrade the application. Please have a look at the Dual-bank and single-bank updates documentation, and notice that after the dual-bank update the application has been invalidated.

We do have an extensive guide for getting started with Nordic's Secure DFU bootloader. It should teach you everything you need to know in order to perform a successful DFU. There is also the BLE Secure DFU Bootloader documentation on Infocenter. Please let us know if something is unclear in the guide or in the documentation, or if there is something written there that you do not understand.

Regards,
Terje
