By the way. The way that NRF_DRV_TIMER_INSTANCE() is implemented depends on what SDK you use, but it should be readable. You only need to change this to use TIMER1, and enable TIMER1 in sdk_config.h as I described in the previous post.

Hello,

The reason for this is probably because you try to use TIMER0 for your TIMER_LED timer. The problem is that TIMER0 is also used by the SoftDevice, so you will get an assert, because the NRF_TIMER0 is already in use.

In the top of the part from your peripheral_timer example, change:

const nrf_drv_timer_t TIMER_LED = NRF_DRV_TIMER_INSTANCE(0);

const nrf_drv_timer_t TIMER_LED = NRF_DRV_TIMER_INSTANCE(1);

And also, you need to enable TIMER1 in your sdk_config.h file.

If you open the sdk_config.h file, you will probably find that TIMER0_ENABLED is defined to 1. Try to also change

#define TIMER1_ENABLED 0

#define TIMER1_ENABLED 1

Then your project should run with the softdevice using TIMER0, and the application timer using TIMER1.

Best regards,
