I try to create coap server project and it should by updateable by DFU. I merge project simple coap server and thread dfu client, and I keep instructions in documentation to build it and run DFU. But Server doesnt response to coap requests and when I start multicast DFU process server is not updated. and when I try to start unicast DFU it waiting to promote a router.
I am folowing this instructions:
first version
D:
cd IS\nRF5_SDK_for_Thread_and_Zigbee_v3.1.0_c7c4730\examples\thread\dfu_client
make -C dfu_client_coap_server\pca10056\blank\armgcc

mergehex -m dfu_client_coap_server\pca10056\blank\armgcc\_build\nrf52840_xxaa.hex settings.hex -o dfu_client.hex

code change
next version

DFU multicast

DFU unicast

Hi,
Can you post the log output? Have you tried to run the DFU client application without the coap server and see if everything works? Can you post your project folder so we can reproduce it?
Best regards,
Marjeris
Thank you, it works.
Is exist any option how to debug dfu client project?
After wtite my code DFU wont start. There is log from flashing DFU:
Address not specified. Using ff03::1 (all Thread nodes) Using connectivity board at serial port: COM12 Flashing connectivity firmware... Connectivity firmware flashed. Waiting for NCP to promote to a router... Thread DFU server is running... Press <Ctrl + D> to stop.
And there is stoped.
There is log from RTT Viewer.

Hi Fran,
You should be able to run a debugger on the application itself as with any other project. But looking at the log output it seems that the settings in flash could be corrupted somehow. You can take a look at the memory layout here, the dfu settings (bootloader settings) are stored near the end. You should check your linker file and adjust your RAM and flash settings accordingly.

it possible add to this dfu project coap client too? Now there is only coap server. I try add coap client but I have problems with communication. On the other site I dont get message.

Hi Fran,
I don't see why this should not be possible. Could you send your code to see how you have implemented this so far?
Best regards,
Marjeris
I solved it, thank you.
