skylab SKB360 module ble problem

[Rajneesh]

Hello,

I am use skylab SKB360 module which are used nRF51822 chip. I have download sample ble application (S110 or S130 softdevice) but its not advertising. Is there any initially firmware needed to bring up this module?

Another thing when I am use simple uart application (without any softdevice) to print something on terminal its working.

Any help will be appreciated

Regards, Rajneesh

Have you flashed the SoftDevice along with the application. It does not look like the SKB360 has an external 32kHz crystal so you might have to set the clock source for the SoftDevice handler to the internal crystal, i.e edit the NRF_CLOCK_LFCLKSRC define to the following

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