Using app_timer with nrf5_SDK_for_Mesh_v1.0.0

[ThomasH]

Is it possible to use app_timer with the mesh stack?

Up to now I was not able to integrate the app_timer library into my build.

Can you give me an example how to integrate it?

What challenges are you facing in trying to integrate app_timer Thomas? As long as you are not using RTC0 i thought it should be pretty straight forward. Did not try it myself though.

Looking at the resources that Mesh SDK uses here. It does not use any RTC (app_timer), so you should in practice be able to use app_timer library from nRF5 SDK without conflicting Mesh resource handling.

Dear Aryan

Integration worked so far.

In the application I call:
    err_code = app_timer_create(&m_testTimer, APP_TIMER_MODE_REPEATED, timer_handler);
    APP_ERROR_CHECK(err_code);

    err_code = app_timer_start(m_testTimer, APP_TIMER_TICKS(50), NULL);
    APP_ERROR_CHECK(err_code);

in order to initialize and start the app_timer

After calling app_timer_create the program crashes.
       5172>, nrf_mesh_sdk.c,   84, HARDFAULT...
       
app_timer_start() is never reached.       

==> I gave up and am using RTC counters instead (that thing works).

Actually I still would like to use the app_timer, but it costs me too much time.

we will integrate app_timer in future releases, please be patient and continue using RTC counters until then.
