Thanks. This solved my problem. By replacing this code: static app_timer_id_t m_battery_timer_id;

for APP_TIMER_DEF(m_battery_timer_id); This did the trick!

For SDK 10 it looks like you have to use this macro (app_timer_start(...) will return NRF_ERROR_INVALID_STATE if the id is zero):

APP_TIMER_DEF(m_battery_timer_id);

I have selected the latest versions of the Software Packs. As far as I know I'm using 10.0.0.

nRF_Examples = 10.0.0
nRF_BLE, Libraries, Drivers, = 3.1.0
FamilyPack = 8.2.0
nRF_Softdevice_S110 = 8.0.3

The error-code after creating the timer is 0, so that should be NRF_SUCCESS.

I will add some of the declaration

#define BATTERY_LEVEL_MEAS_INTERVAL	500  /**< Battery Level measurement interval. */
#define APP_TIMER_PRESCALER             0         /**< Value of the RTC1 PRESCALER register. */

static app_timer_id_t   m_battery_timer_id;     /**< Battery timer. */

Which SDK version are you using? I see that you dont check the error code from app_timer_create(), are you sure this completed successfully?

Thanks for the comment. I checked the error code. It is indeed not NRF_SUCCESS but Code number 8 which suggests NRF_ERROR_INVALID_STATE. But this is still strange for me.

What's 'err_code'? Most likely the APP_ERROR_CHECK() is resetting the device because err_code isnt' NRF_SUCCESS
