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

So when you have only SPI, you get the RX and TX with good data and the UART also with good data. When you initialize BLE the RX has always 0xFF and the TX nothing, and the UART writes bad data. Is that what happens? If you initialize the BLE but don't advertise, it stays the same?
