https://devzone.nordicsemi.com/f/nordic-q-a/2399/what-is-the-difference-between-nrf51822-and-nrf51422Hi, What is the actual difference in hardware between the two chips? I know they support different soft devices but is there any actual difference in the hardware? Or is it a certification thing? If I had the time and patience, would it be possibleen-USTelligent Community 13Thu, 02 Jun 2016 02:30:38 GMThttps://devzone.nordicsemi.com/thread/9777?ContentTypeID=1Thu, 02 Jun 2016 02:30:38 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7950715d-f0fa-4d63-938b-96c76ddbb971helpme<p>Although nRF51822 cannot support ANT, is it possible to get it to support proprietary wlreless standards?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/9776?ContentTypeID=1Thu, 01 May 2014 08:37:16 GMT137ad170-7792-4731-bb38-c0d22fbe4515:571442aa-dbd9-45f8-8c4c-6ed0867ab5fdTim<p>Could you clarify what those missing features are exactly? Is it a different RF modulation method for example?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/9775?ContentTypeID=1Wed, 30 Apr 2014 21:53:37 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4060cf83-2e6c-492b-a279-5b2bb8eeaa96John Leonard<p>Hi Tim, the nRF51822 and nRF51422 share the same HW architecture. ANT is a 3rd party protocol stack. Due to this there are some built-in features on the nRF51422 for using an ANT stack. These features are not present on the nRF51822 and thus any stack that contains ANT will not run on the nRF51822</p> <p>cheers, John</p><div style="clear:both;"></div>
