https://devzone.nordicsemi.com/f/nordic-q-a/32859/combine-hardware-and-softdevice-with-different-versionHello, Can we combine a 5-certified hardware circuit with a softdevice that is 4.2-certified? (at examble mbn52832 (module) with s332 (Softdevice)) If yes, with which version (5 or 4.2) is the End Product certified?
