Question

I am working on a Bluetooth Low Energy (BLE) app. I have a BLE device (scale) which measures weight. I am able to connect with this device. But I am not getting how to read data

Answer 1

you have to differentiate the value is notification or indication, and set respective value using descriptor.setValue. if you set wrongly, you will not get the value.
