Changing Clock Source for NRF52832 in ble_connectivity example

[wr]

Hi, I am trying to use NRF_CLOCK_LF_SRC_RC as clock source with the following settings: pca10040.h #define NRF_CLOCK_LFCLKSRC {.source = NRF_CLOCK_LF_SRC_RC,
.rc_ctiv = 16,
.rc_temp_ctiv = 2,
.xtal_accuracy = NRF_CLOCK_LF_XTAL_ACCURACY_20_PPM} main.c nrf_clock_lf_cfg_t clock_lf_cfg = NRF_CLOCK_LFCLKSRC; SOFTDEVICE_HANDLER_INIT(&clock_lf_cfg, NULL);

soft device: s132_nrf52_2.0.0_softdevice.hex

SDK: 11.0.0_89a8197

Example full path: nRF5_SDK_11.0.0_89a8197\examples\ble_central_and_peripheral\ble_connectivity\pca10040\ser_s132_spi\armgcc

with above settings device is not starting. Can you please confirm these settings are correct for ble_connectivity example?

Thanks

Hi Thanks for the reply. I have a custom board and same example works fine with an external crystal (NRF_CLOCK_LF_SRC_XTAL). Do I need to change anything in the hardware for NRF_CLOCK_LF_SRC_RC to work?

Thanks

Try to remove the xtal_accuracy setting from NRF_CLOCK_LFCLKSRC.
