Can BLE stack work without TIMER0/1/2?

[nordicdev]

I need to use Timer 0,1,and 2(I have only 3 timers 0-2 in nRF51822xxAA). This means, I cannot afford to let the BLE use a timer(I can certainly afford to give one RTC for BLE, I need one RTC for my application). Can the BT stack work without any of timers(0-2)? Thanks.

You can use Timer0 if you use the Timeslot API, but then you can only use it during the requested timeslots. Other than that you can't use Timer0 if you're using BLE.
