App Timer in Ble App Template

[Ars Morozov]

I found that App timer using in ble_app_template in different modules. Is it possible to change prescaler value without harm to other modules? I need to increase maximum value of timer's time, so I need to change prescaler value.

I use SDK 15.1.

Have you considered just having an timeout handler with counter to solve this?

E.g.

static uint16_t m_counter;

static void timeout_handler(void) // Max 250 seconds
{
m_counter ++;

if(m_counter >= TIMEOUT_VALUE) // Multiply of Max 250 seconds

{

m_counter = 0;

// execute code

}

}

Thanks for the answer. Yes, I use this way in my configurations of time counter when interrupt NRF_DRV_RTC_INT_OVERFLOW occure. But in case of using App Timer, I just want to change prescaler value, if it is possible. Will it demage ble_app_template?
I'm really sorry for delayed resopnse, but I'm not receive notification about your message.

Hi,

I don't see any specific problems, unless you also require app_timer with very short timing (e.g. in a few RTC periods with the new prescaler setting).

Best regards,
