Now We have a query that we used nrf52840 chip as a BLE during certification. Now on this Centauri we want to use Open thread stack on nrf52840, Is it allowed to updateen-USTelligent Community 13Thu, 11 Feb 2021 15:09:02 GMTRE: Recertification needed if we change stack from BLE to thread in nrf52840https://devzone.nordicsemi.com/thread/294014?ContentTypeID=1Thu, 11 Feb 2021 15:09:02 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b37f0b37-4659-4425-b01f-b4afabd56741ketiljo<p>The modulation is different for 802.15.4 compared to BLE. So the bandwidth, band edge power etc will be different. It will be necessary to do the FCC testing again. A permissive change is maybe possible. </p><div style="clear:both;"></div>
