Nrf52832 device with dfu future needs to software upload without using bluetooth zip

[oguzhanK]

We are flashing the nRF52832 that works with DFU with a SoftDevice and a bootloader. The application code is compiled privately with a private key and packaged into a zip file. This zip file contains .bat, .json, and .bin files. We transfer this zip file to the device via Bluetooth, and the app runs normally. We cannot upload the code to the device any other way.

Hi Kalsin, 
Could you explain what exactly you need ? 
Do you build the application yourself ? 
If you don't build the application, do you have the hex file instead of the .zip file ? 
If you only have the .zip file, and you want to flash the application directly, you can use the bin file. But you need to tell the bootloader that you have a valid application file. If the bootloader is not aware of that it will not boot the application.
