On the other hand "discoverable on" makes the device show up on other devices during scanning , so the RF parts of the Bluetooth chip are generally functional for sure. Any ideas are welcome. @Bjorn: Patch "arm64: dts: qcom: sm6350: add uart1 node" should be fine to take regardless the RFC status, I don't think the problem is caused there.
