Hi Bjorn, It is working now. I think some settings where changed while checking the problem. I took a fresh code and checked. Now it is working. Thanks a lot Bjorn.

I tried using nRF Connect app. Same thing, it is showing starting DFU but not uploading the packet. Also the log is empty.

Could you try using the nRF Connect app instead and then take a look at the log?

Thanks Bjorn that worked. So, now my device is advertising. I am connecting it with the nrf toolbox app. But while sending the packet it is showing uploading and initializing the DFU process and that is it. It is not moving forward. There is no error message or anything.

Then you need to change the NRF_CLOCK_LFCLKSRC passed to the SOFTDEVICE_HANDLER_APPSH_INIT macro in ble_stack_init() (in the default example its defined in pca10028.h ) to the following

#define NRF_CLOCK_LFCLKSRC      {.source        = NRF_CLOCK_LF_SRC_RC,            \
                                 .rc_ctiv       = 16,                                \
                                 .rc_temp_ctiv  = 2,                                \
                                 .xtal_accuracy = 0}

Hi Bjørn,

PTR5518A is having internal RC oscillator of 32.768kHz. I am not using any external oscillator.

Does the PTR5518A module have the optional 32kHz crystal like the nRF51 DK?
