Yes!

That's all right. Thank you :)

Whoops! I deleted your previous reply on accident. But you wrote that you had fixed the issue by including the init function for the application timer right?

sorry

Hi, Jared

[quote userid="73165" url="~/f/nordic-q-a/75042/app_timer_stop-return-0x04-no-mem-error/309526#309526"] Are you using ble_app_uart_c i.e the central NUS example?[/quote]

My project is based ble_app_uart ! So I added scan module.

I use NRF_DRV_TIMER_INSTANCE.

This is my timer_init code.. and call every 200ns, 1000ns (1ms) in the main.

static void timers_init(void)
{
    ret_code_t err_code ;
    uint32_t time_ticks, time_ticks_us;

    /** added */
    nrf_drv_timer_config_t timer_cfg = NRF_DRV_TIMER_DEFAULT_CONFIG;
    timer_cfg.frequency = 0;
    err_code = nrf_drv_timer_init(&TIMER_MS, &timer_cfg, timer_ms_event_handler);
    APP_ERROR_CHECK(err_code);

    time_ticks = nrf_timer_us_to_ticks(time_ms, 0);
    nrf_drv_timer_extended_compare(
         &TIMER_MS, NRF_TIMER_CC_CHANNEL0, time_ticks, NRF_TIMER_SHORT_COMPARE0_CLEAR_MASK, true);
    nrf_drv_timer_enable(&TIMER_MS);

    //us_timer
    nrf_drv_timer_config_t timer_cfg_2 = NRF_DRV_TIMER_DEFAULT_CONFIG;
    timer_cfg_2.frequency = 0;
    err_code = nrf_drv_timer_init(&TIMER_US, &timer_cfg_2, timer_us_event_handler);
    APP_ERROR_CHECK(err_code);

    time_ticks_us = nrf_timer_us_to_ticks(time_us, 0);
    nrf_drv_timer_extended_compare(&TIMER_US, 
                                    NRF_TIMER_CC_CHANNEL1,
                                    time_ticks_us, 
                                    NRF_TIMER_SHORT_COMPARE1_CLEAR_MASK, 
                                    true);
    nrf_drv_timer_enable(&TIMER_US);
}

This is my main func..

while(1)
{
    sys_us_timer();
    sys_ms_timer();
}

Hi,

[quote user="lyrics"]My project is based 'ble_app_uart.c'.. and I added scan module / two timer interrupt..(ms and ns)[/quote]

What timer instance are you using? Are you using ble_app_uart_c i.e the central NUS example? If you are then it already has the scanner module enabled. Can you share your code?

regards

Jared

My project seems to be a different matter. The error is still not fixed..

For a specific app I had to increase above 100 because I needed repeated calls to app_timer_start and app_timer_stop, that fixed the issue

Best regards,

APP_TIMER_CONFIG_OP_QUEUE_SIZE is set to 10..

so I increase to 20, but still same error. Do I have to set a higher value?..

My project is based 'ble_app_uart.c'.. and I added scan module / two timer interrupt..(ms and ns)

Also it works first connection!

Hi, you can try to increase APP_TIMER_CONFIG_OP_QUEUE_SIZE in sdk_config.h.

You might also consider checking how often you call app_timer library functions, maybe you have frequent unnecessary calls to the library !
