DFU OTA read property "find" and "InstanceID" error in dual-transport

Harry

I have DFU code base working. It consists of a thin layer of our code, and majority is from Bootloader component from SDK v17.

I started with DFU OTA, and then incorporated dual-transport (UART and OTA) by simply including DFU UART source code.

We have 2 custom devices, one is 52832, and the other one is 52833. The DFU Controller is nRF Connect for Desktop v3.5.0

This same source code runs fine on 52832 platform (either in OTA only, or dual-transport).

However, the OTA only works fine on 52833, but the dual-transport doesn't work.

The weird thing is, it advertises fine (I can see the advertising ID), but then when I click "Connect", it popped up as "<Unknown>".

And then shortly I got the read property error.

Please see attached screenshots below.

I also attached the log (and removed some identifying info) below.

And then when I "forced" it, ignoring the error and press "Start DFU", I got: read property "InstanceID" error.

    Hi Harry,

     Please provide the nrf_log output from the bootloader when this issue occurs.

    Hi Amanda,

    Sorry for the delayed response.

    Please find below is the log output from the bootloader. I found that it kept rebooting. This segment you see blow is the full cycle, and it keeps repeating every second (or slightly less).

    The error:

    00> <debug> app: Error 12: ..\..\bootloader\serial_dfu\nrf_dfu_serial_uart.c:150

    I assume the error indicates that it happened at line 150 in nrf_dfu_serial_uart.c. Please see the code snippet below:

    Hi Harry, 

    Are you able to test on nRF52833 DK? If not, is it possible to share the code with us to test on nRF 52833 DK? I can make this private and only it will only be shared  with us (Nordic). 

    -Amanda H.

    Hi Amanda, I have nRF52833 DK, let me try on it.

    As for sharing the code, I will check with my boss first. I heard he mentioned that Nordic and our company already has NDA in place. But let me check with him first.
