nRF51422 SPI is not working properly with BLE

[Ateeb]

I am trying to configure SPI with BLE using softdevice S130. But SPI is not working properly when I used it with BLE, although it is working fine without BLE

If i don't don't advertize in that case sometimes SPI writes and reads successfully and sometimes it does not. I don't understand what is the error. Help me out
