Downgrading Device Manager App

Thanks for the update. Please create a separate ticket for the question regarding memory optimization. It would also be helpful if you included the current configuration settings used in your build. The configuration settings for the bootloader are found in <build folder>/mcuboot/zephyr/.conf and in <build folder>/zephyr/.conf for the app.

Thanks for confirmation, indeed image upload on smp_srv sample works without problem. There were some issues in our frmw.

Currently we have problem with flash consumption. Maybe you could suggest something on how to reduce flash usage of smp_srv sample with BT transport? Some obvious things like removing FS, Stats, Shell, Thread Monitor and Logging I already did, however app with dfu still consumes too much flash.

MCUboot complains that there is not sufficient space to perform swap using move. We did not change partitioning so that should not be the cause of the problem. However frmw grown up by ~20k when we switched from 2.2.0 to 2.4.0 and integrated configuration from smp_srv sample instead of using old approach.

There are several more configs which we used to save flash, but they infringe dfu uploading procedure using new sdk. Maybe you add some comment upon those:

CONFIG_BT_CTLR_DUP_FILTER_LEN=0
CONFIG_BT_CTLR_LE_ENC=n
CONFIG_BT_DATA_LEN_UPDATE=n
CONFIG_BT_CTLR_CHAN_SEL_2=n
CONFIG_BT_CTLR_MIN_USED_CHAN=n
CONFIG_BT_CTLR_PRIVACY=n

Update: Setting CONFIG_BT_PHY_UPDATE=n helped to save some more flash, but still we are close to limit.

Hi,

I've been testing DFU a lot lately using SDK v2.4.0 and Device manager v1.3.1 on iOS and I have not experienced the problems you described, nor have I seen other reports indicating stability issues with these versions. Any chance you could try DFU with the smp_srv sample to see if you are able to reproduce the same problem? It would help narrow down the problem.

Hi Vidar, after moving to NCS 2.4.0 we again have issues with DFU.

It stops in upload procedure at random progress. Setting No. of Buffers to Disabled seems to improve situation but same problem occurs from time to time.

Could you please confirm that latest Device Manager app version 1.3.1 works with NCS 2.4.0?

DFU guide we follow is now updated for newer SDK versions: Add DFU support to your application

I set these two configs related to DFU

CONFIG_BOOTLOADER_MCUBOOT=y

CONFIG_NCS_SAMPLE_MCUMGR_BT_OTA_DFU=y

Also tried to disable speedup, but problem persists.

CONFIG_NCS_SAMPLE_MCUMGR_BT_OTA_DFU_SPEEDUP=n

Thanks in advance.

Thanks. It looks like we have been able to reproduce the problem now. Will keep you posted on the progress.

NCS v1.8.0, nrf52832, MCUBoot settings default.

RE: Downgrading Device Manager App

Vidar Berg — Wed, 23 Nov 2022 10:55:27 GMT

Thanks for confirming. Can you also confirm what the version of the SDK you currently use is, what nRF5x device you are targetting, and if you doing a multi image update or not?

Edit: could you DM me your Apple ID so we can send you a TestFlight invite?

We tested on iPhone 13 Pro, iOS 15.6.1. Disabling buffering did not help.

RE: Downgrading Device Manager App

Vidar Berg — Tue, 22 Nov 2022 13:14:04 GMT

Hello,

That is unfortunate. Could you please let us know what phone you use for testing (model and OS version). Also, if you could try to test without buffering (default is 4):

Hello, DFU was working again with v1.2.8, however on newest version v1.2.10 it stucks after uploading state. Seems that reset is not performed at the end. If we connect with 1.2.8 after uploading, it finalizes the update and it is successful.

It's the same. Connect the iPad to a Mac, run Console app on the Mac, select the connected iPad in the left pane and filter by category, system, etc. Easiest is to find one log, click on the row in System or similar column and click"Show only...". You may need also to enable debug and info logs in View (?) menu.

RE: Downgrading Device Manager App

mesh777 — Thu, 18 Aug 2022 06:13:00 GMT

Is there a way to get logs from iPad?

RE: Downgrading Device Manager App

Aleksander Nowakowski — Wed, 17 Aug 2022 11:49:03 GMT

I believe it would be better to fix the issue, rather than reverting to an older version.

Also, if you have a Mac and Xcode installed, you may run any version of the app from source code.

RE: Downgrading Device Manager App

Aleksander Nowakowski — Wed, 17 Aug 2022 11:47:48 GMT

Hi,
Could you provide logs from the app? If you have a Mac, you should see the logs in "Console" app (native on Mac). Filter the logs by system: com.nordicsemi.nrfconnect.devicemanager (as far as I remember).

Hi,

I will ask again.

[quote user="mesh777"]Regarding firmware I think it does not make sense to share it as it is running on specific hardware. And also I provided link to Nordic instruction which I used to enable updates, so probably you have example project internally, which you could use to test.[/quote]

Yes, that makes sense. The problem is that we have not been able to replicate this on our end, so that is why asked for your FW to test with. Anyway, are you doing a "test and confirm" update from the device manger app. In that case, do you get the same problem if you do a "confirm only" update?

mesh777 — Tue, 16 Aug 2022 12:12:02 GMT

Hi Vidar. Did you ask if it is possible to share older version of the app?

Regarding firmware I think it does not make sense to share it as it is running on specific hardware. And also I provided link to Nordic instruction which I used to enable updates, so probably you have example project internally, which you could use to test.

Vidar Berg — Mon, 08 Aug 2022 14:38:04 GMT

Hello,

That's unfortunate. Would you be able to share the FW + project here or in a private support ticket so we can to replicate it on our end? I can check with the team if there is a way to share the old app with you (with testflight or similar).

mesh777 — Mon, 08 Aug 2022 13:20:45 GMT

Hi Vidar. I tried 1.2.5, unfortunately the problem still exists.

Maybe you can provide 1.2.2 version via TestFlight app?

RE: Downgrading Device Manager App

Dinesh Harjani — Tue, 12 Jul 2022 09:47:55 GMT

I believe this issue has been fixed as of version 1,2.5.

RE: Downgrading Device Manager App

Vidar Berg — Thu, 07 Jul 2022 14:50:31 GMT

The team has submitted a 1.2.5 release to fix another bug the discovered today, which is hopefully the same one you are encountering now. Please let me know when you have been able to try this version.

RE: Downgrading Device Manager App

mesh777 — Wed, 06 Jul 2022 08:16:28 GMT

Yes I tried 1.2.4 version. First attempt to update produces Timeout after Confirmation state. Device does not get reset, however if I reset it manually (e.g. by using Send Reset Command in advanced options of the app) new firmware runs. However if I try to update firmware again I get Timeout after Validating state. Error persists until I erase and re-flash the device.

RE: Downgrading Device Manager App

Vidar Berg — Wed, 06 Jul 2022 07:52:34 GMT

OK, thanks for confirming. I will try with SDK v1.7 or 1.8.0 if I have to try reproduce the problem again.

Did you get a chance to try the new release?

RE: Downgrading Device Manager App

mesh777 — Tue, 05 Jul 2022 10:58:45 GMT

I followed the steps described in the link provided above (section "DFU over Bluetooth"). In our application there are two modes: normal running Mesh and DFU. Switching to DFU mode is done via Mesh command, and application switches back to normal mode after reset. Before entering DFU Mesh is suspended.

On app I use Confirm only mode, as after reset there is no more DFU functionality. And in this way update was always working before. Tested on SDK version 1.7.0 (on 1.8.0 it does not work too), app running on iPad gen7 iOS 14.6.

Hi,

The release is currently being reviewed by Apple so it should be available on the app store soon. However, the developers were less convinced now if it would fix the bug you were experiencing. In case it doesn't, maybe you can provide some more details about your setup? I did not manage to replicate the issue here using the SMP Server Sample.

My setup

- Iphone 12 running ios 15.5

- Device manager app 1.2.3

- nRF connect SDK v2.0.0
