Hello,

The timer setup you use is something you haven't found in your link, right?

I don't know what you expect, but I suspect that you expect the app_timer_create() and app_timer_start() to delay your application for 1 sec. Unfortunately it does not. Besides, you should check the return values from the functions that return values, such as app_timer_create() and app_timer_start. You will see that these will probably not return NRF_SUCCESS, at least not the second time.

If you want to send a notification every 1000ms, you can trigger this from the interrupt handler in the timer, which looks like the uart_event_handle. You should create a separate event handler, not share it with the uart_event_handle.

The point of the APP_TIMER_MODE_REPEATED is that it will reset once you get the timeout event, so you should only start it once.

Look at how the app_timer is used in the ble_app_hrs example. It uses this timer to send a new battery status notification on every timeout.
