FOTA upgrade over BLE crashes (nrf5340)

I have been finally able to perform a FOTA upgrade with nrf5340. Indeed, as they say in the previous github issue it is necessary for the TX and RX l2cap MTU to be the same size. I also needed to select the option "Confirm" in the mobile application so that the bootloader doesn't revert the image back and makes it permanent.

It's still not resolved, unfortunately. I ended up reporting the issue as a bug internally because I couldn't figure out what was causing it. It's currently listed as a known issue for NCS v1.3 + NRF5340: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/doc/release-notes-1.3.0.html#nrf5340

You may monitor the following issue on github to track the status of this bug: https://github.com/zephyrproject-rtos/zephyr/issues/25652

was this issue solved?

If so, could you please provide a brief for the FOTA procedure?

Hi,

Sorry for the delay. I believe I have replicated the same problem here but haven't been able to find out what the problem is yet. Everything appears to work when I repeat the same procedure on a nRF52 target, so it seems like we may have a configuration issue for the 53. I'll continue to investigate this and update the ticket as soon as I have more information to share.
