DFU project

[František]

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. 

[František]

I am folowing this instructions:

first version

cd IS\nRF5_SDK_for_Thread_and_Zigbee_v3.1.0_c7c4730\examples\thread\dfu_client

code change

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

We wanna use it for thousands devices an update firmware without DFU will not possible. 

[František]

If I understand it, I should use coap library which is used in DFU project? 

[Marjeris Romero]

Hi Fran,

That's the buildt-in OpenThread coap library, the external coap library (the one used by the thread DFU client) is this one: https://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.iotsdk.v0.9.0%2Flib_iot_coap.html

I use nRF5_SDK_for_Thread_and_Zigbee_v3.2.0_9fade31

I try example to DFU thread client and I add turn on LED. DFU was sucessfull. Next I add CoAP resources to code and it not start.

This is terminal output:

D:\IS\nRF5_SDK_for_Thread_and_Zigbee_v3.2.0_9fade31\examples\thread\dfu>nrfutil dfu thread -f -pkg app_dfu_package.zip -p COM12 --channel 11 --panid 43981

Hi Fran,

I am so sorry but I am going out on vacation so I will not be able to review your code before the 7th of October. Sorry for the inconvenience and thanks for your patience.

Best regards,

Marjeris
