NRF5340 AUDIO FOTA FAILED

[huniu]

1.I am testing the NRF5340 Audio and fully following the

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/applications/nrf5340_audio/README.html#fota-build-files

Most functions is ok.

However, there is a problem with FOTA. I don't have external flash, so I want to test the internal flash OTA. I just want to upgrade the APP.

3.First I execute this command:

python buildprog. py -c app -b debug -d headset --pristine -m internal -M -p

Burn the headset program to the development board.

4.Then:

python buildprog. py -c app -b debug -d headset --pristine -m internal -M

5.In

\nrf5340_ audio\build\dev_ headset\build_debug\zephyr ,i got

app_ Update.bin and dfu_ Application. zip and other files,

6.I can enter the OTA mode, When I used nRF Connect Device Manage for testing FOTA upgrades.It reply: Error, Value 3

Can you tell me where my problem is?

[huniu]

No,I cant't see anything.

If you can upgrade successfully, can you take an upgrade video for me? I think it will be very helpful.

Hi,

I don't think I will make a video but I am trying to get this to work on my end, it seems it is not as straight-forward as I had hoped.

Which nRF Connect SDK version are you using, and how do you enter OTA mode?

1.My nRF Connect SDK version is v2.1.0。
