https://devzone.nordicsemi.com/f/nordic-q-a/13076/nrf51-standaloneIs it a good idea to use nRF51 standalone as an Application Processor and also as BLE connectivity chip? OR Is it a good practice to use a separate Application Processor? I will mostly be using the Nordic NUS...Please guide..en-USTelligent Community 13Sat, 09 Apr 2016 10:40:06 GMThttps://devzone.nordicsemi.com/thread/49874?ContentTypeID=1Sat, 09 Apr 2016 10:40:06 GMT137ad170-7792-4731-bb38-c0d22fbe4515:78a707cd-f19b-41b7-8dc4-1a318bb41520awneil<p>Apart from processor &quot;load&quot;, Memory sizes could be a deciding factor ...</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/49875?ContentTypeID=1Sat, 09 Apr 2016 10:38:23 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e103697a-e8e8-475e-8f1b-5cc337a3c0c3awneil<p>Clearly, there is no single answer to this - it depends totally on the requirements &amp; constraints of the particular problem at hand.</p> <p>But, in general, why would you want two processors if one will do?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/49873?ContentTypeID=1Sat, 09 Apr 2016 08:00:20 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d4e77021-ca2a-422e-af05-6d130f551e0fwlgrd<p>Agreed. And if processing power is an issue (which in your case it will not be), one could switch to the nRF52 :)</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/49872?ContentTypeID=1Sat, 09 Apr 2016 04:07:19 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a0de5a06-d633-49c6-bcbc-044f4c6811a1RK<p>Standalone. There&#39;s a few cases in which there&#39;s so much processing or realtime requirements that you might need a separate app processor, but they&#39;re rare. If you&#39;re only using the NUS profile it&#39;s pretty unlikely you&#39;ll run up against any issues at all just using the nRF51 on its own.</p><div style="clear:both;"></div>
