Thread Secure OTA DFU Example: Server not responding to Trigger Packet (GET)

Hello Marjeris,

I hope you are fine and safe. Despite the critical moment and all the related difficulties, is there any update with the tests?

Thank you very much.

Best regards,

Michela

Hi again Marjeris,

I would like to add to the previous hints also nrfutile verbose log, both from unicast and multicast modalities.

devzone.nordicsemi.com/.../nrfutil_5F00_log_5F00_multicast.txt devzone.nordicsemi.com/.../nrfutil_5F00_log_5F00_unicast.txt

I kept exactly the previously explained test conditions.

The nrfutil seems to believe that trigger messages were properly sent. However, wireshark sniffer still does not detect any of them.

Hi Marjeris,

Thank you for your reply. I have just run two debug sessions with RTT.

In the first case I run the debugger on the DFU client (the dongle) and then started the DFU server with nrfutil command.

RTT log is the following:

In the second case I just restarted the fw execution on the client (no reprogramming of the dongle) and then started DFU server:

These two trials were done by using the multicast DFU modality. The DFU server, in this case, blocks in this condition:

As for the changes made to adapt the example for the dongle, here is the list:

> client makefile

PROJECT_NAME := thread_secure_dfu_client_pca10059

CFLAGS += -DBOARD_PCA10059

> The same for the bootloader makefile

PROJECT_NAME := thread_secure_dfu_bootloader_secure_dfu_blank_pca10059

CFLAGS += -DBOARD_PCA10059

ASMFLAGS += -DBOARD_PCA10059

Is there a possibility that something is wrong with nrfutil?

Thank you very much for your help despite the difficulties of this period.

Best regards,

Michela

Hi Michela,

Sorry for the late reply. Could you run a debug session and take a look at the RTT log on the DFU client so we can get more information?

The example runs on the nRF52840 DK and I don't see why it shouldn't run on the nRF52840 dongle once you have change the board in the preprocessor definitions in both the bootloader and the dfu client application.

Unfortunately I am working home office and I don't have a nRF52840 dongle with the SWD header soldered to it, so I haven't been able to test the Thread DFU client example on the dongle, but I have asked a colleague to test this for me and he will try again tomorrow.

Just to be sure, you made sure to change the preprocessor definitions flags in the Makefile right?

Best regards,

Marjeris
