How do I integrate the DFU from the heart rate example into the BLE UART (NUS) applciation code?

[Noah]

Hello,

I am using SDk 11.0.0 and I am trying to integrate the DFU from the heart rate example into the my code, which is based upon the BLE UART (NUS) example. When I run the heart rate example on the development kit using the Master Control Panel, I can see that the DFU service is available. However, when the DFU example code has been integrated into my code, I cannot see the DFU service available and thus, cannot select it.

I believe that I am not fully activating the DFU service. Additionally, my code causing an error on line 317 of ble_advdata.c. My uuid value contains the NUS definition, and the softdevice chokes on this. Even after I replaced the uuid value with the value provided in the heart rate example, the error went away, but I am still not able to get the DFU service to display.

Has anyone else had this problem and solved it? Is there a BLE UART example with a built-in DFU? My application has no buttons, so I need this to work.

Thank you!

@Noah: Have you followed this: infocenter.nordicsemi.com/.../bledfu_appextending.html ?

You would need use device manager to use the DFU service.

If you don't plan to use device manager, you can still implement smth similar, but on your own. I'm not sure how you handle bonding data ? What exactly you want to do when you integrate DFU into your application ? You simply want to switch to DFU mode without bonding information ?
