Hello,

[quote user="Kevin6_Lin"]You mean when nRF52840's firmware needs to be updated, I can use trigger mechanism to make nRF52840 enter bootloader mode? The nRF52840 is then able to automatically switch between central and peripheral. Is my understanding correct?[/quote]

Yes that's correct.

[quote user="Kevin6_Lin"]For your suggestion, I'll create a new thread for this question[/quote]

I would really appreciate that.

Hi,

Thanks for the detailed explanation.

You mean when nRF52840's firmware needs to be updated, I can use trigger mechanism to make nRF52840 enter bootloader mode? The nRF52840 is then able to automatically switch between central and peripheral. Is my understanding correct?

If yes, I have an idea about the trigger mechanism. According to our project design, nRF52840 plays a central role (Central HIDS). I can design a button that if short pressed, the nRF52840 will start the peripheral's initial program. It will then enter bootloader mode (SMP server). After the firmware update is complete, the nRF52840 will revert to the central role. For the initialization procedure of peripherals, I can refer to the DFU over Bluetooth section in the guide of Add DFU support to your application. That is, can I add the DFU over Bluetooth part (containing the peripheral code) to the central HIDS code using a trigger mechanism? Is that possible?

For your suggestion, I'll create a new thread for this question.

I really appreciate the help and support that you and Aleksander Nowakowski have given me during these days.

Best Regards,

Kevin

Hi,

The peripheral is a remote control. The use case is that the nRF52840 (central) connects to a remote control (peripheral) and the sample we refer to is Central HIDS. If the user presses a key on the remote control, the remote control will sent a key event to the nRF52840. Then nRF52840 will do the next step we need.

The above situation is under normal use. But if the use case becomes more complex or bugs arise, the nRF52840's firmware will inevitably need to be updated in the future to support more functions or fix problems. When this requirement occurs, we will use the Android/iOS app developed by your company to update the firmware, for example: nRF Connect for Mobile or nRF Connect Device Manager. In this case, the nRF52840 needs to connect to a Android/iOS device (not just a phone) for updating its firmware.

As you said, our situation is probably more like the second one. Glad to hear this feature is actually possible. I'll try to implement it by myself.

For your suggestion, I'll create a new thread for this question.

I really appreciate the help and support that you and Menon have given me during these days.

Best Regards,

Kevin

Hello,

Glad to hear that you finally succeed in doing the OTA DFU.

What Aleksander Mentioned is true. But you can switch between central and peripheral role in the same device. Lets say your Application is working with central role and when it enters bootloader mode for doing the OTA DFU it can turn into peripheral and connect with another device (may be phone). Now the phone(central) can send the image and after a successful upload the chip will reset and your Application will start, acting as central.

This thread is too long. So I also suggest you to start a new case if you have further doubt on this issue. This will keep the Devzone tidy and easy for other users.

Kind Regards,

Abhijith

RE: [NCS v2.2.0] - Device Firmware Update (DFU) via OTA using BLE

Aleksander Nowakowski — Wed, 15 Mar 2023 12:08:04 GMT

Hi,

In your design, what is the device acting as peripheral? Is it another device, or a phone?

When you have a single connection (e.g. phone - device), both sides can have list of services for the other to use. Both sides can do service discovery, read and write each others characteristics as clients and send notifications as servers.

But if you want to have a connection "device A - device B" plus sometimes "phone - device A" to update it, you need to implement it on the fw side. Technically it is possible, but Menon should know much more.

I would recommend creating a new thread for a different issue.

Hi,

I got a real nRF52840DK and tried the same procedure. The result is the same.

But after I thought about it carefully, the content of the test code file you gave earlier is not much different from mine, and there is no problem with the DFU test method I used, so the remaining part of the difference is the computer that builds the code.

After changing to a new computer and testing the same steps, the DFU function is successful, and the preview-DK board can also use the DFU function normally. I am not sure if the path of the original computer to install the SDK is not the default path causing this problem, but after reinstalling the SDK on the original computer with the default path, DFU is also normal.

Please refer to the pictures and attached files below for the results.

devzone.nordicsemi.com/.../nrf52840dk_5F00_dfu_5F00_ble_5F00_2023_2D00_03_2D00_14.log

nRF Connect for Mobile (iOS)

Device Manager (iOS)

Incidentally, because of our project design, the nRF52840 chip plays a central role connecting a peripheral device. However, if the DFU function is to be used, the chip must play the role of a peripheral. Can the chip play the role of the central and peripheral at the same time? Is there any method or information that can be used for reference?

According to the above question, do I need to create a new thread?

Thank you for all your help.

Best Regards,

Kevin

Hello,

Thanks for sharing the details. I strongly suggest to try with our DK and I don't have a PDK right now for testing this. Please try with DK and let me know if the same is happening.

Hi Abhijith,

Ok, I'll figure out how to get an nRF52840DK. After that I will try the same procedure again and let you know the result.

I have tried the method you provided. The result is the same.

All the commands I used and the results are as follows.

The build command

Hello,

Please see that you are not trying with nRF52840DK your hardware is a preview development kit. PDKs should only be used for evaluation purposes, and I would recommend getting a DK instead. PDK is not officially supported by our new nRF connect SDK.

As a last try use west command line for building and flashing the application and see whether the same is happening.

RE: [NCS v2.2.0] - Device Firmware Update (DFU) via OTA using BLE

Kevin Lin — Wed, 01 Mar 2023 09:32:26 GMT

Hi,

Well... maybe there is something wrong with my code. But I followed all the procedures in the guide, even the sample code. Other than that, I didn't add or modify anything, except adding a test log to the test image.

I'm not sure if I use the secondary slots for external storage. As mentioned above, I followed all the steps in the guide and didn't change anything except the test logs. Or maybe I missed somewhere.

In addition, I also suspect that another possible place is the device tree setting. The DTS of nRF52840DK in NCS v.2.2.0 is here: nrf52840dk_nrf52840.dts.

The screenshot below shows the result of my following your advice.

devzone.nordicsemi.com/.../nRF_5F00_Logger_5F00_2023_2D00_03_2D00_01_5F00_14_5F00_46_5F00_33.txt

devzone.nordicsemi.com/.../minicom_5F00_android_5F00_nrf52840dk_5F00_dfu_5F00_ble_5F00_2023_2D00_03_2D00_01.log

1. First, "READ" the image on the Advanced screen after connecting to the nRF52840DK.

2. In "Firmware Upload" section, upload a image named "app_update.bin" and choose "Application Core".

3. The upload process.

4. The State will show "UPLOAD COMPLETE" after the process is completed.

5. "READ" the image again. You will see there are two images in the nRF52840DK.

6. The result after clicking "CONFIRM" option. It will display "Invalid value (3)".

7. Next, "TEST" the new image after "READ" the images again.

8. Send a "RESET" command.

9. After reset the nRF52840DK, the current image will change to the new image.

10. If you send a "RESET" command again, you will see the current image is reversed.

The following results show what we tried using Device manager on iOS.

1. First, "READ" the image on the Advanced screen after connecting to the nRF52840DK.

2. In IMAGE UPGRADE section, choose a image named "dfu_application.zip" to upgrade.

3. Choose "Confirm Only" option.

4. Then it will display "Remote error: In Value (3)" on the State.

5. "READ" the image and there will be two images in the nRF52840DK.

6. Next, use "Test And Confirm" option to test.

7. After upgrading the image, it will reset the nRF52840DK.

8. Confirm the new image.

9. The result is the same as "Confirm Only" option because the new image cannot be confirmed successfully.

10. "READ" the images again. The nRF52840DK boots from the new image.

11. "RESET" the nRF52840DK to check if it will boot from the new image next time.

12. The current image has been inverted to the original image.

The following results show what we tried using nRF Connect on iOS.

devzone.nordicsemi.com/.../nRF_5F00_Connect_5F00_IOS_5F00_2023_2D00_03_2D00_01.txt

1. Connect to the nRF52840DK in nRF Connect.

2. The infrmation of the nRF52840DK.

3. Read the image using "List" option.

4. In DFU seciton, Select a image name "dfu_application.zip" to upgrade.

5. The additional information in DFU section.

6. The upgrade process.

7. There will be an error window pop up after the process is completed. It displayed "Remote error: In Value (3)".

Please feel free to let me know if you need anything else.

Thanks again for your help.

Best Regards,

Kevin

Hi, I had a talk with a firmware developer familiar with MCU manager.

First of all we confirm that dfu works on our side. We used NCS 2.2. That may indicate an issue in your code out setup.

Are you using external storage for the secondary slots?

After you read the image state on Image 4 above, could you then click Confirm button instead of trying upgrade with Test & Confirm? On the Advanced screen you can upload the image and then select Confirm manually. Did you try that?

Did you also try using nRF Connect Device Manager on iOS?

RE: [NCS v2.2.0] - Device Firmware Update (DFU) via OTA using BLE

Menon — Fri, 24 Feb 2023 12:36:39 GMT

Hello,

I was just trying the OTA DFU with NCS v2.2.0 and it's working fine on my side. I am attaching the project file may be you can give a try with this file. Could you also share the whole project so that I can go through and will try to reproduce this here. I checked with device Manager App version1.5.2

Hello,

Sure, we also tried nRF connect Mobile App. The result seems to be the same as nRF Connect Device Manager. We also recorded the same two logs as above, please refer to below.

devzone.nordicsemi.com/.../nRF_5F00_Connect_5F00_Log_5F00_2023_2D00_02_2D00_24_5F00_12_5F00_42_5F00_42.txt

Here is the process we did.

1. Scan results on nRF Connect. you can see the Nordic_LBS device.

2. Connect to the Nordic_LBS device. the result as follows.

3. Click "DFU" icon in the upper right corner and choose "Confirm only" option to update.

4. This is the result after the "Confirm only" process is completed.

5. Then use "Test and Confirm" option to try again.

6. This is the result after the "Test and Confirm" process is completed.

7. Finally, execute the "nrfjprog -r" command to test if the board will boot from the new image.

Thanks.

Best Regards,

Kevin

Hi,

Thank you for your prompt reply.

Do you mean that the problem is that the value of CONFIG_IMG_MGMT_UPDATABLE_IMAGE_NUMBER in the configuration is set incorrectly?

Is my understanding correct? If yes, its default value in .config was as follows:

CONFIG_IMG_MGMT_UPDATABLE_IMAGE_NUMBER=1

Then I added its new value in prj.conf for testing, as follows:

CONFIG_IMG_MGMT_UPDATABLE_IMAGE_NUMBER=2

I also list the prj.conf settings based on guidelines.

From the build log, it seems that the failure is caused by this reason:

/mnt/hdd/nordic/v2.2.0/zephyr/subsys/mgmt/mcumgr/lib/cmd/img_mgmt/src/img_mgmt_priv.c:29:1: error: static assertion failed: "Missing partitions?"
   29 | BUILD_ASSERT(CONFIG_IMG_MGMT_UPDATABLE_IMAGE_NUMBER == 1 ||
      | ^~~~~~~~~~~~

Is it because the partition is not set, or other reasons? If yes, how do we set up partitions?

By the way, we use nRF Connect for VS Code (Linux) for development.

Thanks again for your help.

Best Regards,

I also asked fw guru to check if there are no issues on the mcumgr side.

Hello,

Please go through the First response.

Have you tried the same using the nRF connect Mobile App? Please give a try and let me know the result.

Kind Regards,

Abhijith

Hi,

I will go with you through the code of mcumgr subsystem from where you're getting the error.

First, have a look here: https://github.com/nrfconnect/sdk-zephyr/blob/0cd59b0c43aa0c9d6682066aca74ac05be094169/subsys/mgmt/mcumgr/grp/img_mgmt/src/img_mgmt.c#L585. This is where handlers for different commands are registered. The confirm or test commands are sent as Write to IMG_MGMT_ID_STATE command to Image group, that means we need to check img_mgmt_state_write method.:

https://github.com/nrfconnect/sdk-zephyr/blob/0cd59b0c43aa0c9d6682066aca74ac05be094169/subsys/mgmt/mcumgr/grp/img_mgmt/src/img_mgmt_state.c#L274

We are looking for places where an error called MGMT_ERR_EINVAL is returned as rc.

I assume the decoding here: https://github.com/nrfconnect/sdk-zephyr/blob/0cd59b0c43aa0c9d6682066aca74ac05be094169/subsys/mgmt/mcumgr/grp/img_mgmt/src/img_mgmt_state.c#L290 works, as it is called both when you have confirm=false and confirm=true. The first case seems to be working properly. It sets the pending flag to true. After reset the device is swapping images and runs the new image, which is correct. This method fails when confirm is true, which means the error must come later.

The hash sent is equal in both cases, so this also doesn't end here: https://github.com/nrfconnect/sdk-zephyr/blob/0cd59b0c43aa0c9d6682066aca74ac05be094169/subsys/mgmt/mcumgr/grp/img_mgmt/src/img_mgmt_state.c#L305

Then, the next possible place is here: https://github.com/nrfconnect/sdk-zephyr/blob/0cd59b0c43aa0c9d6682066aca74ac05be094169/subsys/mgmt/mcumgr/grp/img_mgmt/src/img_mgmt_state.c#L315 where the manager is looking for the image to be confirmed. This method is defined here: https://github.com/nrfconnect/sdk-zephyr/blob/0cd59b0c43aa0c9d6682066aca74ac05be094169/subsys/mgmt/mcumgr/grp/img_mgmt/src/img_mgmt.c#L233-L247 indicating that perhaps CONFIG_IMG_MGMT_UPDATABLE_IMAGE_NUMBER isn't set properly.

Check this out:

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/1.9.1/kconfig/CONFIG_IMG_MGMT_UPDATABLE_IMAGE_NUMBER.html#std-kconfig-CONFIG_IMG_MGMT_UPDATABLE_IMAGE_NUMBER

If that's not the case, try going further that path. But I suspect that may be it. The next method is just returning the state of images, which is again called for test and confirm, so should work the same way.

Hope that helped!
