SPIM Transfer Data

Hi, Support team,

When I use the SPI peripheral communicate with nrf24l01+,it's no data return in  m_rx_buf by using the API nrf_drv_spi_transfer(&spi,m_tx_buf,1, m_rx_buf, 3),.but when I  use the logic analysis it have data in MISO ,so what should I do?

    It's done! Thank for you advance! I have found the reason why no rx_buf data,because of my mistake for connect the MISO pin to Pin26(it's a 32,768KHz crystal Pin );By the way ,I have a another question about sdk_config.h file,it's generated by some tools?  because i found this file have two tabs-Text Editor and Configuration Wizard,and how to generate my own sdk_config.h files?
