https://devzone.nordicsemi.com/f/nordic-q-a/16277/why-the-nrf51422-can-flash-ble-and-ant-but-51822-can-tI have checked the datasheet between 51422 and 51822,they look the same,but why the NRF51422 can flash BLE and ANT+,but 51822 can&#39;t? Is the Radio part different,or the Flash，RAM structure？Now I want use 51822 to develop BLE central,but the SDK9.0 exampleen-USTelligent Community 13Thu, 08 Sep 2016 06:51:20 GMThttps://devzone.nordicsemi.com/thread/62223?ContentTypeID=1Thu, 08 Sep 2016 06:51:20 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9f2e96b7-97c0-4093-a6c9-7c313b55b1b1Einar Thorsrud<p>The <em>only</em> difference between NRF51422 and 51822 is that the 51822 cannot support ANT. This is for cost reasons, as the extra cost of the NRF51422 is for the rights to use ANT. The hardware is exactly the same in all other aspects, including the radio, flash, RAM and everything else.</p><div style="clear:both;"></div>
