Hi.
Quick intro:
I have followed this: nRF52840 Advanced Development With the nRF5 SDK.
And with this tutorial I was able to test a lot of nRF5 SDK examples. And all they I tested worked very good!
However when I tried to do the same for the nrf5 Mesh SDK, it didn’t work. Because they have all the examples have a different structure and the compilation is also different.
Problem:
Following nordic guide I was able to compile all mesh examples successfully, but was not able to flash them using make, ninja or nrfjprog.
After that I noticed that in nRF5 SDK we did this:
0)get hex file using make
-
generate dfu_zip: nrfutil dfu genpkg --sd-req 0xFFFE --dev-type 0x0052 --application nrf52840_xxaa.hex _build/dfu-package.zip
-
Place controller in DFU Mode
-
nrfutil --verbose dfu serial --package _build/dfu-package.zip -p $(SERIAL_PORT) -b 115200 --singlebank --touch 1200
So I tried the same, for the mesh examples, trying with:
light_switch_server_nrf52840_xxAA_s140_7.0.1.hex and light_switch_server_nrf52840_xxAA_s140_7.0.1_merged.hex
Since they were the only hex files I had generated with ninja/make.
I flashed one, tested, flashed another tested. And since the nordic mobile app didn’t detect my device, I concluded that the program was not doing what it was supposed. I tried to debug using the TX pin, but in nrf-mesh-sdk the sdk_config.h doesn’t have any NRF_LOG_BACKEND_UART variable.
It has a NRF_LOG_ENABLED variable but when I change to 1. It doesn’t compile :o
What I would dream with 
:
See a tutorial at least half as good as you have for nRF-SDK for nrf-mesh-sdk.
