https://devzone.nordicsemi.com/f/nordic-q-a/38947/nrf24l01-spi-command-problemHi all, I&#39;m developing a custom board that is equipped with a nRF24L01+ (directly soldered on my PCB, no breakout). The board is equipped with a PIC32, that controls also the nRF. I&#39;m writing a driver to do that, since there is a posix-like osal thaten-USTelligent Community 13Thu, 27 Sep 2018 16:22:52 GMThttps://devzone.nordicsemi.com/thread/150761?ContentTypeID=1Thu, 27 Sep 2018 16:22:52 GMT137ad170-7792-4731-bb38-c0d22fbe4515:88f87549-b980-439f-8302-60007237b3fagabbla<p>You are right, there was a wrong byte mask in my code, thanks a lot!<br /><br />Gabriele</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/150717?ContentTypeID=1Thu, 27 Sep 2018 13:00:27 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0f0ea58d-3aec-4b91-917c-45d8bcc226b1Kenneth<p>Hello,</p> <p>Seems the SPI configuration is wrong. The Arduino update&nbsp;MOSI on falling CLK edge (correct), while on PIC32 you update MOSI on rising edge (wrong).</p> <p>Best regards,<br />Kenneth</p><div style="clear:both;"></div>
