Hi;

I am trying to secure DFU OTA. For that, i am using SDK12.2.0 and done with example file.

Now how to generate this .dat file itself.

Hi Nilesh,

you can generate firmware images for the Secure Bootloader using our nrfutil tool, which is available here on GitHub.

Install instructions and examples on how to generate the firmware images are given in the READM.md file.

Best regards

Also i am trying to generate my own hex file for DFU OTA in mbed tool with shadow platform. First i am trying with BLE_LED example and select shadow platform. So, is there require any extra line into the code? Unfortunately it's also not working for me.
