I am using SPI interface to collect data from the slave(ads1192) and transmitted it to nrf52 DK,previously,I just used RTT to show the received data, but now i try to use uart and ble to build communication between PC and smartphone. so i used ble-app-uart example and add spi function into the example. the problem is that when i added the spi function into it , the spi part will not run properly but the ble still can work. is there any interference between ble and spi?

You can retarget printf so that what you print is sent over UART. You can see how this is done in the UART example. The key concept is that you can retarget the printf wherever you like, such as over UART. This is implemented in /components/libraries/uart/retarget.c.
