Soft Device app_timer lib : what is the maximum number of timers

[Sébastien Despont]

Dear Nordic support team,

What is the maximum number of timers that I can create (and use) using the app_timer lib?

    err_code = app_timer_create(&m_timer_m_1_0,
                                APP_TIMER_MODE_REPEATED,
                                timer_m_1_0_timeout_handler);

I have tried to initializate 10 timers this morning which are not all involved at the same times. It seems to work, but I can't find the limitation in the source code app_timer.c or in the documentation.

And same question for the maximum number of the "operation queues size".

Best regards

There is a separate define in your application to set the maximum amount of timers, APP_TIMER_MAX_TIMERS. As long as you don't run out of RAM, I'm not aware of any specific limit for how big this can be.

As for the operation queue size, I posted that as a separate question here, as the answer is a little complicated. Please take a look at it, and let's keep that discussion there if anything is unclear.
