LFCLK: RC oscillator is not calibrated when first started.

[Fiske]

I am using SDK12.0.0. ble_app_uart example, and I have change the clock to using LFCLK RC. I know from nRF51822-PAN_v3.1.pdf that we need to calibrate the LFCLK RC after reset. Right. Please tell me the codes to calibrate the oscillator and where should I place it.

If you have selected LFCLK RC to be used by softdevice, then the softdevice will automatically do this for you as soon as you enable it.
