It is surprising how often the basics get missed, when embroiled in heat of battle of programmer vs hardware, operating system, complex apis and libraries, etc. I have found that whenever my BLE2...

Using BluetoothGatt, the way to set the Phy is via setPrefferedPhy and to read the Phy is to use readPhy. Both methods communicate their results using callbacks via the BluetoothGattCallback. This wish is to expose the callbacks onPhyRead and onPhyUpdate. This would round out (actually implement every callback in BluetoothGattCallback) the already excellent updated BLE2 library....

It is simpler to use and it is more powerful. Its API is based on B4i iBLE library which makes it easy to reuse B4i code. See the iBLE tutorial: https://www.b4x.com/android/forum/threads/ble-bluetooth-low-energy-library.46099/#content Tips & Notes - You can call Manager.Scan2 with AllowDuplicates set to True if you want to monitor the state...
