I am building an app that receives data from a custom built Bluetooth low energy device. Development info regarding BLE in Kivy is pretty scarce, but what I did find was this conversation in the Pyjinius development group which was very helpful (
https://groups.google.com/forum/#!topic/pyjnius-dev/yId8td6YZiI).
The conversation at one point states that there will never be a way to implement an abstract java classes using Pyjnius. The reason this matters is because the BluetoothGattCallback in Android is an abstract class, thus presenting a significant hurdle. The conversation is fairly old, so I am curious if this is still the case?
I saw that there is a lengthy work around to the problem but I wanted to check first.
