I have two nrf52 where i send a msg to one nrf52 through ble_app_uart that has SPI Master(This is working).
I am trying to configure one more nrf with ble_app_uart with SPIS .
I am not able to receive any data in the customised program that has both Ble_app_uart and SPIS.
But I am able to receive the data in peripheral/SPIS program.
