Hi,

The bootloader will not advertise unless it has received the bonding information from the app first. So in order to test DFU with bond forwarding you need to 1. program the softdevice+bootloader+app+settings page 2. connect to the app perform bonding. 3. initiate DFU through the buttonless service. Or did you follow these steps already?

Also, you may know this, but I just want to point out that the app will still support bonding if you disable the NRF_DFU_BLE_REQUIRES_BONDS config option. This flag is only to enable bond forwarding to the bootloader.

From the SDK documentation: Testing Buttonless Secure DFU with bonds

Hi,

Can i continue here with the issue? I am facing something similar and to your question, bootloader does compile but it does not advertise at all unless i disable the bond forwarding support in it.

Also, here is something i am having trouble with in SDK 15.3 --> https://devzone.nordicsemi.com/f/nordic-q-a/55705/application-service-uuid-gone-after-secure-ota-dfu

No problem. Just let me know when you're ready to revisit this issue.

Hi,

Could you verify that the bootloader is compiled with the NRF_DFU_BLE_REQUIRES_BONDS option enabled in sdk_config.h? The bootloader will not support bond forwarding otherwise.

By the way, the issue mentioned in the thread you linked to is fixed in SDK 16.0.0
