Why did you use 0x0080 for the --sd-req ? If you are testing with S110 v8.0 you should use 0x0064 , or you can use 0xFFFE to avoid softdevice checking. Have you tried to test with the ble_app_hrs with dfu unmodified ?

yes, I flashed the bootloader.

I used nrfutil.exe tool to generate the .zip file. I used the following command to generate it.

C:\Program Files (x86)\Nordic Semiconductor\Master Control Panel\3.10.0.14\nrf>nrfutil dfu genpkg --application"C:\Users\kishor.babu\Downloads\nRF51_SDK_10.0.0_dc26b5e\examples\ble_peripheral\ble_app_hrs\pca10028\s110_with_dfu\arm5_no_packs\_build\nrf51422_xxac_s110.hex" --application-version 4 --dev-revision 0xffff --dev-type 0xffff --sd-req 0x0080 "D:\dfu_test\dfu_hrs.zip"

After generating .zip file, when I tried to update the it via OTA using nrf connect it is showing "operation failed" error.

The same procedure I followed and tried with sdk 11 and it is updating the firmware.

But I need to do this by using sdk v 10.0.0 only.

How can I make it to work?

Have you made sure you flashed the bootloader ?

To generate the .zip package, you would need the nrf.exe tool. This tool comes with the nRF Master Control Panel. Please have a look at this guide, at question G

Have you managed to test the ble_app_hrs with dfu ?

Hi Hung BUi,

Thanks for the reply, I forgot to define BLE_DFU_APP_SUPPORT.

Now I included it and when I connect to Nordic_UART, DFU is displayed on the top of nrf connect application.

But when i am pressing DFU and trying to update the test image "dfu_test_app_hrm_s110" it is not uploading showing the error "DFU DEVICE IS DISCONNECTED" after some time in nrf connect application.

One more thing I want to know is, is there any particular procedure to create "dfu.zip" for an application "particularly for sdk v 10.0.0".

Hi,

Could you post a screenshot of what you have inside nRFConnect after it discovers the services ?

When you add the dfu service into your application, please make sure you have all the API calls to add service and characteristic return NRF_SUCCESS and that you have increased the number of VS_UUID in your application.
