Hi, 
 The handle is just a handle to the GATT table, and not standardized. In principle it can also change with a new versino of the device you are connecting to (it is normally automtically assigned). The normal way to get the handle is to perform a service discovery. I do not have any other methods to suggest. That said, there are some very specific use cases we have seen in the past where this may be usefull, and it is possible with the old SoftDevice and nRF5 SDK. If you are using that, you can refer to this thread .
