Modulation Characteristics, LE Coded (S=8) RF-PHY/TRM-LE/CA/BV-13-C tests are not possible with the nrf52840.https://devzone.nordicsemi.com/f/nordic-q-a/90715/modulation-characteristics-le-coded-s-8-rf-phy-trm-le-ca-bv-13-c-tests-are-not-possible-with-the-nrf52840Hi, I&#39;m doing a Bluetooth test for the nrf52840. However, RF-PHY/TRM-LE/CA/BV-13-C cannot be tested. This means that the instrument does not provide results. The measuring instrument uses Rohde &amp; Schwarz CMW270 Bluetooth Tester.
