nRF52832 Bluetooth Keil configuration

Question

Hi i just bough module E73-TBB(nRF52832) from EBYTE . I've already downloaded the sdk this link https://www.nordicsemi.com/Products/nRF52832/Download#infotabs 
 I test with ble_app_blinky ( Keil uVision5 ), uploaded success work as normal. but example Bluetooth Uart not working (no device found from my phone); 
 does module need special configuration for oscillator ?

Hi, does module need special configuration for oscillator ? Yes, in sdk_config.h, you need to configure it like this: //========================================================== // Clock - SoftDevice clock configuration //========================================================== // NRF_SDH_CLOCK_LF_SRC - SoftDevice clock source. // <0=> NRF_CLOCK_LF_SRC_RC // <1=> NRF_CLOCK_LF_SRC_XTAL // <2=> NRF_CLOCK_LF_SRC_SYNTH #ifndef NRF_SDH_CLOCK_LF_SRC #define NRF_SDH_CLOCK_LF_SRC 0 #endif // NRF_SDH_CLOCK_LF_RC_CTIV - SoftDevice calibration timer interval. #ifndef NRF_SDH_CLOCK_LF_RC_CTIV #define NRF_SDH_CLOCK_LF_RC_CTIV 16 #endif // NRF_SDH_CLOCK_LF_RC_TEMP_CTIV - SoftDevice calibration timer interval under constant temperature. // How often (in number of calibration intervals) the RC oscillator shall be calibrated // if the temperature has not changed. #ifndef NRF_SDH_CLOCK_LF_RC_TEMP_CTIV #define NRF_SDH_CLOCK_LF_RC_TEMP_CTIV 2 #endif // NRF_SDH_CLOCK_LF_ACCURACY - External clock accuracy used in the LL to compute timing. // <0=> NRF_CLOCK_LF_ACCURACY_250_PPM // <1=> NRF_CLOCK_LF_ACCURACY_500_PPM // <2=> NRF_CLOCK_LF_ACCURACY_150_PPM // <3=> NRF_CLOCK_LF_ACCURACY_100_PPM // <4=> NRF_CLOCK_LF_ACCURACY_75_PPM // <5=> NRF_CLOCK_LF_ACCURACY_50_PPM // <6=> NRF_CLOCK_LF_ACCURACY_30_PPM // <7=> NRF_CLOCK_LF_ACCURACY_20_PPM // <8=> NRF_CLOCK_LF_ACCURACY_10_PPM // <9=> NRF_CLOCK_LF_ACCURACY_5_PPM // <10=> NRF_CLOCK_LF_ACCURACY_2_PPM // <11=> NRF_CLOCK_LF_ACCURACY_1_PPM #ifndef NRF_SDH_CLOCK_LF_ACCURACY #define NRF_SDH_CLOCK_LF_ACCURACY 1 #endif

 Good. One difference between Keil and SES projects, is that the SES projects are configured to flash the SoftDevice for you.
