Hi Simon.

No more help needed thanks. I copied the code from the RTC example, and set it to use RTC2 and that worked ok in the end thanks.

Did you find a sufficient solution, or do you need any more help?

YES I KNOW obviously, or I wouldn't be asking a question. I tried to read the error code in the first place, and the system crashes for some reason at APP_ERROR_CHECK(err_code).

I have setup a new RTC timer now which works fine and ditched the app_timer.

Thanks HAVE A NICE DAY

That APP_TIMER_DEF() only defines a few variables. You are still missing the calls to app_timer_create().

Those error codes are supposed to tell you that something is WRONG WITH YOUR CODE.

Thanks. I have registered the timer if this is what you mean;

APP_TIMER_DEF(adv_timer);

If I do an APP_ERROR_CHECK on the app_timer_start there is a Fatal system error for some reason, so had to delete that error check. Not sure why since it should return a ret_code_t type

Check the return value on your app_timer_start() call, you forgot to register your timer.

APP_TIMER will stop the RTC when there are no timers running, unless APP_TIMER_KEEPS_RTC_ACTIVE is set to nonzero.
