https://devzone.nordicsemi.com/f/nordic-q-a/46801/rf-module-certification-and-apache-mynewtAll nRF52832 based RF modules on the market have been certified using a Nordic SoftDevice. Some manufacturers say that it is ok to use a different Nordic SoftDevice without invalidating the certification.

And, yes, you can reuse the RF-PHY for the rigado module.</p> <p>One thing you need to watch for is if the module manufacturer has made a qualified design referencing nordic component for LL and Host. If you use a newer softdevice you might not be able to reference that design as the newer SD would support a different feature set. However in that that case you could reference Nordics qualified design and the module manufacturers RF-PHY test and you would be fine.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/184727?ContentTypeID=1Wed, 01 May 2019 20:29:13 GMT137ad170-7792-4731-bb38-c0d22fbe4515:beba284e-3746-4102-9375-388a55ae2da0Michael Lawton<p>I received a good answer about this from Rigado.<br /><br />Installing any BT stack or firmware on the chip will not invalidate the RF/EMC certification as the frequency, modulation etc are all controlled by the chip itself and the firmware only controls higher level functions.</p> <p>According to Rigado the Bluetooth RF-PHY QDID for their module can be used for the end product so no extra Bluetooth testing should be needed. I think I have seen some conflicting information here saying RF-PHY testing is always needed as the final hardware is different than the standalone module. Can anyone else chime in with a second opinion on this?</p><div style="clear:both;"></div>
