https://devzone.nordicsemi.com/f/nordic-q-a/15143/read-data-from-spi-is-not-added-to-the-bufferHey guys! I am using your spi-master driver from the SDK 11 with the nRF52 chip. I am trying to read data from a MPU-9250 chip, and through my logic analysis, it seems like everything works well. My problem is that the data on the MISO-line isn&#39;t alwaysen-USTelligent Community 13Thu, 14 Jul 2016 08:41:54 GMThttps://devzone.nordicsemi.com/thread/57808?ContentTypeID=1Thu, 14 Jul 2016 08:41:54 GMT137ad170-7792-4731-bb38-c0d22fbe4515:57ec169d-abbf-442d-8a67-16117431f676Henrik<p>I fixed it myself!</p> <p>I initialized the SPI-driver with an event handler, but the event handler didn&#39;t do anything. By removing the event handler, the transfer function returns when it is finished.</p> <p>I found the following in the info center:</p> <blockquote> <p>If an event handler was provided in the nrf_drv_spi_init call, this function returns immediately and the handler is called when the transfer is done. Otherwise, the transfer is performed in blocking mode, which means that this function returns when the transfer is finished.</p> </blockquote> <p>I should have read it more thoroughly! Anyhow, thanks!</p><div style="clear:both;"></div>
