Where can we find the exact information per timer? The datasheets do not provide much, except for the registers and the 5 timers available in the nRF52.

Unfortunately having the same problem over here. Timer0 and timer3 running perfectly fine, but timer2 does not want to generate an interrupt. Configuration is exactly the same, and they are not running at the same time. Changed to timer 4 for the moment.

Hi, That does not make sense. sd_app_evt_wait will not mask TIMER2 interrupt in anyways. It is designed to exit wait states even if there are any pending interrupts. can you please upload your code with this problem reproducible.

I disabled a sd_app_evt_wait() call.

what did you disable? are you going to system off without a wakeup source?

Ok, I disabled power management now (sleep mode i think) and the interrupt works now.

changed it to 16 bit now, but it still isn't interupting

is this nRF51? for it TImer1 and timer2 only supports 16bit mode. So BIT_WIDTH should be 0

according to the sdk_config.h bit_width can be 0-3:

// <o> TIMER_DEFAULT_CONFIG_BIT_WIDTH  - Timer counter bit width
 
// <0=> 16 bit 
// <1=> 8 bit 
// <2=> 24 bit 
// <3=> 32 bit

seems all good .. can you check all the values of NRF_DRV_TIMER_DEFAULT_CONFIG in your config file?
