How to use ble_uart example using 16Mhz. without 32khz

[cirid]

i think ble_uart example based on 32Khz. but my board do not have 32khz osc.(by miss design)

how to running ble_uart example using only 16Mhz?

thank you for your answer. i see that softdevice_handler_init() in ble_stack_init(). replaced NRF_LFCLKSRC_RC_250_4000ms_CALIBRATION(also start HFCLK, TASKs_CAL, and check 16mHZ output at osc), but didn'y working. my circuit is reference on QFAA QFN48 schematic with low voltage mode setup(exactly same without 32khz)
