Hello, I want to use Bluetooth 4.0 to connect the Vert device. The problem is,that I have android 4.4, but your official example is based on android 6.0. I rebuilded this example to work on my device, it starts with problems (I can connect and get BleService(s)/BleCharacteristic(s), but haracteristic.getValue("...") always null ). So can you say what is wrong, and what should I do to get Vert's values ?
