Programming nRF51822 on custom board. Advertising is not working.

Question

Hello, 
 I have simple custom PCB with nRF51822.
I am trying to make it advertise like a beacon, by program it with ble_app_beacon example from nRF5_SDK examples.
I have also nRF51DK, and I use J-Link programmer on this board to program my custom board.
Beacon example works fine on nRF51DK, but when I put it on my custom board with nRF51822, nothing happens, there is no advertising.
To program my board I use nRFGO studio, s132 soft device. 
 Any ideas what I am doing wrong?

Hi, 
 First off the S132 SoftDevice is not compatible with the nRF51, use S130 instead. For further reference please see the compatibility matrix . 
 Are you configuring you external clock correctly? 
 Start the SoftDevice by calling SOFTDEVICE_HANDLER_INIT (NRF_CLOCK_LFCLKSRC_XTAL_20_PPM, false); 
 Note that this function will take some time since it starts the crystal (~300ms). 
 Replace NRF_CLOCK_LFCLKSRC_XTAL_20_PPM with the LF clock you are using , eg. for an internal RC clock use NRF_CLOCK_LFCLKSRC_RC_250_PPM_TEMP_4000MS_CALIBRATION for example. 
 Best regards, 
 Øyvind
