https://devzone.nordicsemi.com/f/nordic-q-a/42326/nrf52-spi-manager-need-gap-between-bytesI&#39;m using nRF52 and SDK 15.2 with SPI Manager (NRF_SPI_MNGR_ENABLED) with EasyDMA disabled. Some of the external chips I&#39;m communicating with via SPI can&#39;t handle consecutive bytes back-to-back. They require a time gap between each byte sent.

In the meantime, I remove the use of SPI Manager and am sending bytes directly in app context. It works, but I&#39;m not too excited about it because the &#39;waitTilNotBusy&#39; calls between bytes are blocking code instead of async callbacks. Oh well, the overall communication burst time is sub-millisecond so hopefully won&#39;t impact the other app context operations.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/165500?ContentTypeID=1Mon, 14 Jan 2019 14:21:02 GMT137ad170-7792-4731-bb38-c0d22fbe4515:29ff8385-e07b-4436-83d2-17895604ec1aStian R&#248;ed Hafskjold<p>Hi, I&#39;m not really sure if there are any easy ways to do this with the SPI driver. You can consider implementing your own SPI driver and combine it with a TIMER instance to send the bytes in a regular interval.</p><div style="clear:both;"></div>
