Hi,

[quote user="Jesus Velasquez"]Is there any sample ready to use for nrf52840 ?[/quote]

You can use the peripheral_lbs sample with those three configs.

[quote user="Jesus Velasquez"] it stuck ther.Am I missing some step ?[/quote]

Do you update with the same pm_static.yml?

To perform DFU, you must define a static partition map because the dynamically generated partitions can change between builds. This is also important when you use a precompiled HEX file as a child image instead of building it. In such cases, the newly generated application images may no longer use a partition map compatible with the partition map used by the bootloader. As a result, the newly built application image may not be bootable by the bootloader. See Static partition requirement for DFU doc.

To create pm_static, I would start by doing the following:

Open sample_pm_static.yml
Open your old build/partitions.yml
Observe that the content in the autogenerated file is similar to the pm_static file from the two files above.
Open <your_project>/pm_static.yml
Copy app and mcuboot content from partitions.yml to pm_static.yml
Compare with sample_pm_static.yml and remove all parts of yml that are not needed (such as end_address)
Try to build the project.

HI,

About Mobile app is ok . related to mcuboot issue , I'm using NCS 2.5 . I got my BT BLE project (peripheral ) and just adding this

I was able to perform a firmware upgrade using nRF-Connect-Device-Manager , but seems like somethis is missing .Is there any sample ready to use for nrf52840 ? .The error that I get is a timeout at mobile application.And at the device side

and it stuck ther.Am I missing some step ? I'm using the app-update.bin fron build folder to update

Hi,

[quote user="Jesus Velasquez"] I want to know if I can do another app customized .[/quote]

Not sure if I understand the question correctly or not. You could develop your app, but our support is based on the nRF-Connect-Device-Manager mobile app. On the nRF-Connect-Device-Manager mobile app page link, there are iOS and Android source codes for reference.

[quote user="Jesus Velasquez"]I'm getting issues when I do the upgrade , sometimes it perform the update but get stuck there and I need to manually reset [/quote]

With which app, nRF-Connect-Device-Manager mobile app or another app customized?

Which NCS version are you using? Could you try the last version v2.5.2?

Could you provide the log from the nRF-Connect-Device-Manager mobile app and the device?

Hi,

You can use https://www.nordicsemi.com/Products/Development-tools/nRF-Connect-Device-Manager mobile app to update.

[quote user="Jesus Velasquez"]How do I know all the requeriments for BT firmware upgrade ? like advertising limitations[/quote]

The firmware is only processed during the connection instead of advertising.

Hello Amanda H

thanks for the quick reply , I was able to generate static partition by copying que generated after activate mcu boot . I was able to make work part of the BT application with the firmware upgrade. It seems to be hidden .But I notice that the advertising that I'm using is not supported .So I was planning to put the mcu in certain advertising mode for the firmware upgrade. Besides this, Is there any soruce code , library or similar to integrate the firmware upgrade to an existing mobile app ? . And How do I know all the requeriments for BT firmware upgrade ? like advertising limitations

Thanks in advance

Hi,

Check out my colleague's sample https://github.com/hellesvik-nordic/samples_for_nrf_connect_sdk/tree/main/bootloader_samples/smp/mcuboot_smp_ble.

If you want to perform DFU, you must define a static partition map because the dynamically generated partitions can change between builds. This is important also when you use a precompiled HEX file as a child image instead of building it. In such cases, the newly generated application images may no longer use a partition map that is compatible with the partition map used by the bootloader. As a result, the newly built application image may not be bootable by the bootloader. See Static partition requirement for DFU doc.

To create pm_static, I would start by doing the following:

Open sample_pm_static.yml
Open your old build/partitions.yml
Observe that content in autogenerated file is similar to pm_static file from the two files above.
Open <your_project>/pm_static.yml
Copy app and mcuboot content from partitions.yml to pm_static.yml
Compare with sample_pm_static.yml and remove all parts of yml that is not needed (such as end_address)
Try to build project.
