OTA DFU on NORA B1

[Jirik]

Hello,

I have a project working on Nora B1, which I am testing on nrf5340DK. It is based on the Peripheral UART Sample, programmed with nfr Connect SDK v1.9.1. Now I need to add the OTA DFU to update the program from the nrf Connect mobile app. I changed the prj.conf and main according to this tutorial

https://getwavecake.com/blog/adding-ota-dfu-to-a-nordic-zephyr-project/

It works perfectly, when I am testing it on the Development Kit, but it does not work at all on the Nora B1. The flash is succesful, but the BLE can't get initialised.

I tried a bit and it seems like the problem is caused by the line

CONFIG_BOOTLOADER_MCUBOOT=y

when I add this to the prj. conf, BLE does not work, even when I did not do any changes in the main.

Is there anything special I should take care about while configuring bootloader on the NoraB1?

Thanks a lot for any answer

Hello,

It is good to hear that you are considering the new SDK versions.

Yes, I have seen this error before, but as far as I remember, this error will not affect your DFU process. We are working on this error message internally. Have you tested the whole DFU process?

Take a look at this old thread, which discusses the same issue.

 Please expect some delay after this response as we are having Easter vacation here in Norway and we are only very few working. Sorry if this creates any inconvenience.

Kind Regards,

Abhijith

The Problem is, that after this message, I don't get any output anymore from the COM port, and the DK is not advertising.
