https://devzone.nordicsemi.com/f/nordic-q-a/25559/nrf52810-compatibilityI have several question regarding the backward compatibility of the nRF52810. By Bluetooth 5.0 FAQ Document the Bluetooth certified 5.0 devices are backward compatible with ALL previous revisions and futures of Bluetooth and BLE. Is it true theen-USTelligent Community 13Fri, 29 Sep 2017 09:25:19 GMThttps://devzone.nordicsemi.com/thread/100766?ContentTypeID=1Fri, 29 Sep 2017 09:25:19 GMT137ad170-7792-4731-bb38-c0d22fbe4515:92cbbfac-e2ed-4a48-9a52-5f46e7bcd57aovrebekk<p>Hi</p> <p>The nRF52810 will be backwards with all previous version of Bluetooth low energy, that is correct. This means that the nRF52810 can communicate with BLE devices based on the 4.0, 4.1, 4.2 or 5 specification.</p> <p>Or as stated in the FAQ:<br /> &quot;Devices implementing only the low energy feature of Bluetooth 5 will be backward compatible with Bluetooth 4.2, 4.1 and 4.0 devices that also implement the low energy feature. &quot;</p> <p>The nRF52810 will not be able to communicate with so called classic Bluetooth devices, running in the BR, EDR or HS modes (Nordic doesn&#39;t make any devices for classic Bluetooth).</p> <p>Best regards<br /> Torbjørn</p><div style="clear:both;"></div>
