Reading characteristic user description in android

[MH]

Hi,

I have successfully add the characteristic user description into all of my characteristics.

I used master control panel to verify that my characteristics has characteristic user description such as: SWITCH-1 (a meaning full name for me) but I have problem getting this description from the android application.

In my android application I’m able to find the services and characteristics but I don’t know how to read the characteristic user description value, I search the web many time with no luck, but I can see that android master control panel from Nordic can read the characteristic user description.

Please give me suggestion to read characteristic user description on android device.

Hi MH,

You can use the getDescriptor() function from BluetoothGattCharacteristic to read the descriptor. To read User Description descriptor you would need to getDescriptor(UUID) with UUID = 00002901-0000-1000-8000-00805f9b34fb

You can refer to how we get the CCCD (00002902-0000-1000-8000-00805f9b34fb) in our examples, for example in enableTXNotification() function in nRFUART app example.
