Thank you for the help. I found what the issue was, I had not defined DFU enable in preprocessor definitions.

Hi,

I recommend you look at the Buttonless DFU Template Application example which demonstrate buttonless DFU.

To disable bond share, you must set NRF_DFU_BLE_REQUIRES_BONDS to 0 in the sdk_config.h for the bootloader. This is the default configuration of the examples. You should also set NRF_DFU_BLE_BUTTONLESS_SUPPORTS_BONDS to 0 for the application. This is also default configuration for the Buttonless DFU Template Application.

I have tried to use bootloader with bot configuration. But I want to use bootloader without bond sharing.

Once the device enters the DFU mode it stops advertising( if I comment out nrf_dfu_button_check()) , I cannot see the device on nrF connect. I dont have the logs now but I will try to get it and post it here.

In the meanwhile if you have any suggestion so that I can enter DFU mode without bond sharing and without using button, it would be really appreciated.

Thanks.

Hi,

Can you elaborate a bit more about what configuration you have? Are you using the bootloader with or without bond sharing? What happens when you attempt to enter DFU mode (after the disconnect? Which state is the device in? Any relevant logs or similar?
