Hello sir, As i was programming via nrf51DK to my custom board ,after i power cycled the DK i can see the advertising of DK not the custom board. after programming i powered up the custom board alone but nothing advertised .

Pavan, you state in your original question you first could not see it broadcasting, but then you write "but when i remove the connection and power ON the DK i can see the connectivity". Do you mean that after you have power cycled the board you can see it advertising?

Hello,

I changed as per the above but no change in still nothing is showing, i can see my module is detected in nrfgo studio i,e nrf51822 . i am just building the code and dragging the hex file and copying it to the detected jlink in my pc

Go through the link properly: infocenter.nordicsemi.com/index.jsp

NRF_CLOCK_LF_SRC_RC- Internal 32 kHz RC oscillator. NRF_CLOCK_LF_SRC_Xtal- External 32 kHz crystal. NRF_CLOCK_LF_SRC_Synth -Internal 32 kHz synthesizer from HFCLK system clock.

Change the clock source in else part as follows: ifdef S210 define NRF_CLOCK_LFCLKSRC NRF_CLOCK_LF_SRC_RC else #define NRF_CLOCK_LFCLKSRC {.source = NRF_CLOCK_LF_SRC_RC, \ .rc_ctiv = 0, \ .rc_temp_ctiv = 0, \ .xtal_accuracy = NRF_CLOCK_LF_XTAL_ACCURACY_20_PPM}

I am using SDK_12.3.0_d7731ad and soft device "s130_nrf51_2.0.1_softdevice". first erasing the board using nrfgo and programming soft device with same and the programming application via kei in my nrfgo its detected as nrf51422 though i connected it to my custom board . with below settings

ifdef S210 define NRF_CLOCK_LFCLKSRC NRF_CLOCK_LF_SRC_RC else

#define NRF_CLOCK_LFCLKSRC {.source = NRF_CLOCK_LF_SRC_XTAL, \ .rc_ctiv = 0, \ .rc_temp_ctiv = 0, \ .xtal_accuracy = NRF_CLOCK_LF_XTAL_ACCURACY_20_PPM} pavan (1 hour ago)

I changed my settings in pca10028.h as below but still no change

// Low frequency clock source to be used by the SoftDevice #ifdef S210 #define NRF_CLOCK_LFCLKSRC NRF_CLOCK_LF_SRC_RC #else #define NRF_CLOCK_LFCLKSRC {.source = NRF_CLOCK_LF_SRC_XTAL,
.rc_ctiv = 0,
.rc_temp_ctiv = 0,
.xtal_accuracy = NRF_CLOCK_LF_XTAL_ACCURACY_20_PPM}

Search in header files (PCA10028.h)

I am searching for that line but zero results found , in which file i will get it

Hi Dhiraj , Thank you for your information, i will be using UART_BLE program can u please tel me where exactly to change that or by adding external crystal will solve my issue?

Search for this: #define NRF_CLOCK_LFCLKSRC in header file Follow this link: infocenter.nordicsemi.com/index.jsp

Hello Pavan,

I faced same issue before. You can search for clk source in the code. Change the clk source to internal clock, the device will broadcast properly.
