Issues with DFU Library for Android and iOS

Aftab

Hi,

We are facing issue with upgrading our devices using DFU library. 

Despite using the latest version of the Nordic iOS DFU Library, the firmware update process exhibits inconsistent behavior.

Here are the details of the issues:

  1. Intermittent Success:

    • Firmware updates sometimes complete successfully, but at other times, they fail unpredictably.
    • The same module may accept the firmware update in one attempt but fail or get stuck during subsequent tries.

  2. Most Common Issues Observed:

    • The firmware update process completes with a success message at the end, but the module does not actually update its firmware.
    • The progress bar or update process gets stuck midway, requiring a retry.

  3. Inconsistent Results:

    • At times, all modules update successfully in one go. However, in other cases, it takes up to three attempts to achieve the same outcome.

The behavior seems unexpected and doesn’t point to a clear pattern. I would appreciate it if you could share any insights or recommendations to resolve this. If you’ve experienced similar issues or have suggestions for debugging, they would be incredibly helpful.

While we use the DFU app for Android (version 2.7.0), the DFU works most of the time without any issue. Is there any difference b/w library used by DFU app and that available for development?

We are using nRF52840 devices and the SDK version at their end is 16.0.

Best regards.

    Hi,

    It is difficult to say much without more information. Some questions:

    1. Does this also fail sometimes if you use nRF Connect for Mobile to perform DFU, or does it only fail withour mobile application
    2. Do you have logs from the mobile side you can share that shows both a successfull and failed update?
    3. Are you able to test with a debug bootlaoder with RTT logging so that we can see hwat is happening on the nRF side? If so, can you share logs both of the working and failing case?

    Thanks for the reply.

    1. The DFU rarely fails when PC app used, does not fail if DFU app used on Android phone

    2. Attached is the log from the data returned from the DFU library on our iOS device

    3. I'm not able to run the debug version but planning to run one in the coming working days. Generally we use non debug version on our devices.

    Regards.

    I see, that is good information.

    I do not see the attachment. Can you try uploading again?

    That is understood. I am not suggesting using the debug version in production, but only to do it while debugging to understand what is going wrong durign the DFU procedure.

    Sorry, below are the logs from the iOS app. I'll run the debug version as well and update the ticket.
