mcumgr over openthread UDP Error 8

[kalbani]

I'm trying to implement mcumgr over openthread UDP. to update firmware.

mcumgr echo works fine but when I try to list images the respond is Error 8.

I'm using nrf52840 with nrf connect SDK 2.2.0.

+ is this the right implementation of DFU using openthread?

Hi, 

Not sure how you set SMP over UPD in the application, but you could refer to and test the SMP Server Sample and build with the overlay-udp.conf.

Hello Amanda,

I followed the instruction on the SMP Server Sample, I just integrated OpenThread with the sample.

Instructions like echo and stat are working but anything related to the image will give me error 8.

I looked for the meaning of error 8 and it seems to mean that the command is not supported. not sure if thats the case or if something is wrong with my code

Before integrating, do you test  SMP Server Sample with overlay-udp.conf? Do you get any errors?

[kalbani]

I just tried the SMP sample with connection over ethernet it seems to be working fine unlike with openthread

[Amanda Hsieh]

Do you add the configs in this overlay-udp.conf into your project config?
This similar case might help, but it needs to increase CONFIG_SYSTEM_WORKQUEUE_STACK_SIZE.
