RE: BLE Mesh DFU failed to update

Edvin — Tue, 11 Mar 2025 08:24:12 GMT

Is there some way for me to reproduce what you are seeing? Is it possible to send the appilcation that you are using on the nRFs, and some instructions to follow the procedure that you are doing?

If I see the same as you, I can run it by our Mesh team.

Best regards,

Edvin

I tried it few times and it always fails, sometimes it takes longer but always fails.

Hello,

Sorry for the late reply. Other traffic over the network may cause packet loss, but I don't think it is supposed to fail like this. If you try to run the DFU once more after it failed, does it work then? Does it keep it's progress, or will it transfer everything from scratch?

Best regards,

Edvin

When I have other devices running on BLE mesh but with my vendor model it looks that then there is a problem with update, is it possible that other devices interrupt process of DFU?

And after some blocks of data, update failed, here is the logs:

RE: BLE Mesh DFU failed to update

Bartosz22 — Mon, 24 Feb 2025 10:43:40 GMT

Ok I think I found the issue, I wrongly send the data at the unicast address of the first element which is the distributor, not on the second. So now it seems to be working, I'm currently checking it. But how can I do the self update? Just set the address of the element 2 on this device and start update?

RE: BLE Mesh DFU failed to update

Bartosz22 — Mon, 24 Feb 2025 09:08:34 GMT

Yes, I flashed both devices with the same application.
So, here are the steps how I do it:
1) Flashed two NRF52840DK with this example software: https://github.com/nrfconnect/sdk-nrf/tree/main/samples/bluetooth/mesh/dfu/distributor
2) In the BLE mesh app from phone according to instruction I provision and assigned app key 1 to Firmware Distribution Server, Firmware Update Client, BLOB Transfer Server, BLOB Transfer Client, Firmware Update Server and BLOB Transfer Server on each of the two NRF52840DK boards.
3) Then form the mobile Device Manager app I connected to one of the NRF52840DK and as decribed here: https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/protocols/bt/bt_mesh/dfu_over_bt_mesh.html I uploaded the distributor.signed.bin file, added slot using shell from Device Manager app using mesh commands, added receivers list - firstly I tried to add unicast addresses of both devices then only of the self device and at the end I started the update process with command mesh models dfd start 0 0
At the end I got this error which you can see in the log I provided.

RE: BLE Mesh DFU failed to update

Edvin — Fri, 21 Feb 2025 21:23:58 GMT

Hello,

Sorry for the late reply.

So you flashed both devices with this application, and then tried to perform the DFU with the same application, right?

Can you please try to increase the CONFIG_MCUBOOT_IMGTOOL_SIGN_VERSION in prj.conf, then rebuild and try again?

Other than that, did you try the test description described in the sample:

https://github.com/nrfconnect/sdk-nrf/tree/main/samples/bluetooth/mesh/dfu/distributor#testing

Regardless, can you please explain what you did in details, and explain where it doesn't behave as expected.

Best regards,

Edvin
