Dear, We are developing the nRF51822 for an application of BLE device. The timer is the key process in the application. Anyone kindly share the experience with me about the APP timer and normal timer(timer0/timer1/timer2). How do I know to use the timers and it would not impact the APP timer? Actually, I would like to generate a frequency during 30KHz ~ 40KHz. By the way, does the APP timer use a software timer based on timers (timer0 or timer1 or timer2 or RTC timer)? if so, what is the limit number?
