mesh integration on existing firmware -- Program dwells on unknown function

[Juliusc]

Hi,

I just recently began implementing the mesh stack into an existing application, using mesh v3.2 and nrf sdk 15.2. 

Integration works well by using the integration guide provided in the infocenter, but the mesh doesn't start after initializiation.

in detail I basically tried implementing the mesh_main.c file from the sdk_coexist proximity example, initialization seems to work alright, my services are still visible on LightBlue but as soo as I start the mesh stack my programs will suspend on an unknown function 0x978. This doesn't happen in the SoftDevice but rather at the end of the nrf_mesh_enable function. Debugging doesn't give me an error either, the program basically just stops.

Any hints on what is going on here? I copied most of the configuration from the proximity coexist example as flash_placement specs and configurations from the app_config file, only some settings have to stay the same as before. 

Im using a nrf52840 and SD140 6.1.0

Would appreciate any kind of help!

Hi Julius, 
I think the best way now is to start from scratch. I don't say that you need to re-implement you application from scratch but to use a BLE example (the one that you based your application on) and then add mesh in to the example. 
This way if anything go wrong the same way as in your application it would be much easier to debug. 

Regarding the timer, please double check and make sure app_timer_mesh.c is used, not app_timer.c

Im quite sure that timers are the biggest problem here indeed and even starting from scratch its hard to just change all the settings without having 200 errors rain upon me. Ill need to set a plan on how to proceed but right now I feel lost with mesh
