Bluetooth Smart (aka Bluetooth Low Energy – BLE) is not the same as Bluetooth.
Unfortunately PandwaRF cannot use normal Bluetooth.
We have added this message “The device does not have a Bluetooth feature” to indicate the lack of Bluetooth Smart HW support from your phone.
In doubt, please install System Info for Android or equivalent and check in System/Functionalities if you see android.hardware.bluetooth.le.
If you don’t, your phone doesn’t support Bluetooth Smart. Keep it preciously, it is a collector.
