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

In spi_test() function I am just writing and reading from a sensor, nothing detailed. I also have gone through it step by step, first I write through api and then read it, sometimes read is successful as write was successful sometimes its not.
