Please tell me,
I have stock Sony, Orange branded 4.3 android version. Not rooted, clean. I read on Sony device papers that Xperia M supports Bluetooth 4.0. Android supports it since 4.3 . But it seems like it doesn't support Bluetooth Low Energy protocol I care about. Is it possible that another Android version (eg. CM) will support it? Does anybody used it with any BLE device for sure? How is this possible that my phone sees target device but cannot further communicate?
