Mesh DFU New Firmware message after DFU update.

[him]

Hi

    Mesh DFU shows New firmware message after DFU update and gets stuck in the DFU mode. I have assigned different application id to all the boards.

Right now I am using nrf52833 DK as a serial DFU source and a custom board as the target and some custom boards in between to relay packets all with different application id's. DFU is successful but after the target device updated it gets new firmware message and gets stuck in the DFU mode.

I have read this case nRF52833 --MESH DFU---there is show "New firmware" message after update with dfu..... - Nordic Q&A - Nordic DevZone - Nordic DevZone https://devzone.nordicsemi.com/f/nordic-q-a/74218/nrf52833---mesh-dfu---there-is-show-new-firmware-message-after-update-with-dfu but didn't solve my problem also Hung bui mentioned about some bug fixes for DFU but didn't tell what it is.

I am using the following firmware:-

Mesh SDK :- v4.2.0

Nrf5 SDK :- v16.0

SoC :-  nrf52833

DFU source fw :- DFU serial example.

DFU target fw :- DFU no serial example.

Thanks

Hello,

Is there any way for me to reproduce what you are seeing using one or two DKs? If so, can you add a detailed description including all of the nrfutil commands that you are using?

BR,

Hi Edvin,

 Thanks for the response. 

The node that started receiving DFU, but aborted due to packet miss starts broadcasting new firmware message.

I hope I am right.

Thanks
