The stock LPN client for Mesh SDK v4.0.0 throws NRF_MESH_EVT_SAR_FAILED when replying to a publication set message via a friend node.
All code, reproduction data and log output is here: https://github.com/siriobalmelli/nrf_mesh_4.0.0_lpn_SAR
I also tried to implement the suggested answer from this thread:
... this did not work, see this commit:
Have you made any modification to the LPN example?
I'm not sure if this will make any difference but could you also try using our nRF Mesh app instead of the BubblyNet app? Any difference?
Thanks for looking at this.
Confirmed I'm getting NRF_MESH_EVT_SAR_FAILED with the nRF Mesh App also
