Thanks again Kristin, I ended up figuring it out. It seemed to be an issue with my SPI master. Thanks so much for your help. All is great now.

Okay, I see. Do you have an extra nRF52/51-DK? If so, could you try the SPI <---> SPIS example in the SDK?

When you have received data, could you read the memory location to check if the data is there, see my updated answer above.

Thanks Kristin, I was actually calling the buffers_set function after the init. I updated the code above to represent what I was doing. I am still unable to get data into my rx buffer. Is there something I am doing wrong? I get the correct rx_length when the handler is called, but the buffer is empty.

In addition to initializing SPIS driver, the SPI buffers must be set after the initialization of the driver. To do so, nrf_drv_spis_buffers_set() should be used, see the "using the SPI slave driver" section in the SDK documentation.

Update 08.02.2017: The screenshot below shows that "Nordic" has been received in memory location 0x2000008 (RXD.PTR)
