Avoid entering over the air bootloader but start with preprogrammed app

We had the same problem and solved it by creating a hex file that contains a prepared bootloader setting with installed app. By using mergehex.exe we combine bootloader, application, softdevice and the initial bootloader setting to one hex file that is programmed in factory.

You need to set the boot loader settings so that the application is marked as valid when you pre-program your application like so:

uint8_t  m_boot_settings[CODE_PAGE_SIZE] __attribute__((at(BOOTLOADER_SETTINGS_ADDRESS))) __attribute__((used)) = {BANK_VALID_APP};

Maybe one of these questions can help you?
