Dear Nordic Team,

Thanks for supporting.

Now i am trying to work DFU with NUS example.I am following As per nordic document like: infocenter.nordicsemi.com/index.jsp

And also follow the example code for ble_app_hrs. After compile the hex file is make as a zip file using nrfutil exe. This zip file also uploaded successfully through nordic mobile APP. But application is not run in my hardware. For your reference my main.c also attached. Please support , i dont know what i am doing wrong.

My Code : main.c My SDK =SDK11 and Hardware =PCA10028

  • Hi Murugan,

    First please test just the DFU bootloader and the unmodified ble_app_hrs and let me know if you can update and if the application run. Then try to jump to bootloader (holding a button for example) and update again same application. After that test with your application (no DFU service integrated) make sure DFU OTA works with your application.

    Only after that, you can try to integrate the buttonless DFU service into your application and test.
