App timer in mesh

[huybk213]

Hi everyone.

In mesh light switch example., i try to add timer0 (or any timer).

After initialize timer, application always jump to timeout event, and i don't know why.

My code working perfectly in nRF SDK v15, but not working in Mesh SDK.

Any body have a solution to add timer into mesh project?

Here is my timer_config function.

const nrf_drv_timer_t TIMER_LED = NRF_DRV_TIMER_INSTANCE(0);
void timeout_config(uint32_t milisecond)
{
    uint32_t time_ms = milisecond; //Time(in miliseconds) between consecutive compare events.
    uint32_t time_ticks;
    uint32_t err_code = NRF_SUCCESS;
    
    nrf_drv_timer_config_t timer_cfg = NRF_DRV_TIMER_DEFAULT_CONFIG;
    err_code = nrf_drv_timer_init(&TIMER_PROVISION, &timer_cfg, provision_timeout_event_handler);
    APP_ERROR_CHECK(err_code);

    // time_ticks = nrf_drv_timer_ms_to_ticks(&TIMER_PROVISION, time_ms);

    nrfx_timer_compare(&TIMER_PROVISION,
                        NRF_TIMER_CC_CHANNEL1,
                        time_ms,
                        true);
     nrf_drv_timer_enable(&TIMER_PROVISION);
}

 

My event handle function

void provision_timeout_event_handler(nrf_timer_event_t event_type, void* p_context)
{
    switch (event_type)
    {
        case NRF_TIMER_EVENT_COMPARE0:
            bsp_board_led_invert(1);
            break;

        default:
            //Do nothing.
            break;
    }
}

main:

int main()
{
    timeout_config(5000);       // 5000ms
    timeout_start();
    initialize();
    execution_start(start);
    while(1) {}
}

Thank you so much!

Timer 0 is required by the softdevice to ensure that the application doesn't use the peripherals any longer than the radio timeslot length, and is specified in the SoftDevice Specification. Using timer 1 will probably solve the problem.

Thanks Simon.

But I've try other timer, problem did not resolved. Program always jump to timer interrupt.
