Hi Hung Bui,

Update:

The DFU example is working with SDK 15.3 for both debug and non-debug version. I checked the working with --application-version and --application-version-string, both worked.

I really have no clue about why it didn't work yesterday! I had followed the exact same procedure.

In fact I tried programming nrfjprog and SEGGER Embedded Studio. Both are working for SDK 15.3 and SD 6.1.1 (debug and non-debug).

Thank you for your quick responses.

Sure, I will give it a try.

Also, currently I am trying with the debug version of dfu example for SDK 15.3-SoftDevice_6.1.1 as this is the actual target device. I will update you if the debug version works. After which, I will try the non-debug version to see if it causes problems.

That way, I can be sure that debug version works and see if the non-debug version has a problem.

Could you try not to use --application-version-string and use --application-version instead ?

Could you check the log on the phone to see what's the error ?

Hi Hung Bui,

When I used SDK 15.3, I have used the SoftDevice version 6.1.1. Since it didn't work, now I tried with SDK 16.0, which did not work either for non-debug version.

nrfutil pkg generate --application ble_app_uart_pca10040_s132.hex --application-version-string "1.0.0" --hw-version 52 --sd-req 0xCB --key-file private.key app_v1.zip

Everything works fine until the last part where I update the firmware of the DfuTarg. I will also check the log as you have suggested.

Please let me know if something else has to be done.

Thank you!

Hi Navin,

If the debug version work and the release version doesn't it could be that the version checking of the DFU image was failed.

Could you please post how you created the DFU .zip image ? Please also state the softdevice version you flashed on board. If you are using SDK v15.3 the softdevice you should use is S132 v6.1.1 not v7.0.1 . And you would need to match the correct softdevice version in the --sd-req when you create the image.

Note that you can see the log when doing DFU by swiping right, or by installing our nRFLog app.

I tried the debug version of the dfu example and it works with the smartphone. Any ideas why it is not working with the non-debug version?
