Hi.

TIMER2 is exactly the same as TIMER1, so if TIMER1 doesn't work, then perhaps you use it somewhere else in your code?

Hi Ray.

TIMER0 is blocked when the SoftDevice is enabled. You can see this in the hardware access table in the infocenter.
You can also see in this table that TIMER1 and TIMER2 is open, so you should use these.
