https://devzone.nordicsemi.com/f/nordic-q-a/34651/multi-threaded-queue-accessSDK14.2 A little background on this question. I am creating a library where I need to add items to a queue and then process those items from the queue. I would like to know what SDK library would be better for this operation: nrf_queue or nrf_atfifoen-USTelligent Community 13Wed, 23 May 2018 14:26:02 GMThttps://devzone.nordicsemi.com/thread/133046?ContentTypeID=1Wed, 23 May 2018 14:26:02 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9a8e1219-d9a3-4032-9d1b-ce679f83aef7Susheel Nuguru<p>Hi Superpak,</p> <p>I think your question is if nrf_queue or nrf_fifo library is best suited for you?</p> <p>nrf_fifo is designed to work with bytes of data data where as <a href="http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.sdk5.v15.0.0%2Flib_queue.html&amp;cp=4_0_0_3_34">queues </a>implementation is more of object oriented concepts where you can push and pop pre defined objects. Also the queues are documented to be more interrupt safe and i am quite positive that nrf_fifo has not been tested to be interrupt safe.</p> <p>I would have used queues if it were me to choose.</p> <p>&nbsp;</p><div style="clear:both;"></div>
