RE: To enter dfu mode from application buttonless

Hi,

Please look at the following

1. Have you built the bootloader code by enabling "#define NRF_BL_DFU_ENTER_METHOD_BUTTONLESS 1" in sdk_config.h

You don't need to change any lines in bootloder file...only you have to focus on sdk_config.h of bootloader code

There are few setting needs to be done in your application code as well as bootloader code.

Follow the below post which is having clear instructions about button as well as buttonless DFU process

Follow the below document also which I followed and it worked.

Regards,
